Product Spotlight: Rockford Fosgate PMX-1

Rockford Fosgate PMX-1

As much fun as it is to check out top-of-the-line products, sometimes the right solution is surprisingly affordable. The marine and powersport audio experts at Rockford Fosgate offer a full line of digital media receivers. In fact, there are five stand-alone units, plus an add-on multi-zone unit with several controller options. There is, indeed, a solution for every application. We will highlight the affordable but full-featured PMX-1 Punch-Series marine-grade receiver in this spotlight.

PMX-1 Physical Design

When we talk about source units, we usually discuss single or double DIN units designed for cars and trucks. The PMX-1 chassis, designed for marine and powersports applications, is intended to be flush-mounted on a flat panel. Rockford Fosgate has several vehicle-specific audio upgrade kits for side-by-sides that include mounting provisions for this unit.

Rockford Fosgate PMX-1
The RZR14-STG1 audio kit for Polaris RZR vehicles includes a PMX-1, speakers, and a mounting pod that fits on the top of the dash.

The face of the PMX-1 is 4.5 inches wide and 4.2 inches tall. It protrudes 1.5 inches forward of the mounting surface, and the chassis and heatsink extend 2.9 inches rearward. The kit includes a rubber mounting gasket to ensure the face seals perfectly against the mounting surface.

The radio can be installed in one of two ways. If you have a dash with a round three-inch mounting hole, your installer can mount the radio using the supplied aluminum U-bracket, just like a speedometer or tachometer in a boat. Alternatively, the kit includes a metal mounting bracket that can be positioned behind the mounting surface, and four screws secure the display to the plate and sandwich on either side of the mounting surface. An included trim ring conceals the mounting hardware once in place.

Two mounting options are provided to maximize installation options.

The radio is rated to have an IPX6 water intrusion rating, so you can blast it all day long with a hose or let it get hit by waves. This is crucial in Rockford Fosgate’s Element Ready™ marine, motorcycle, and powersport products. Further, the radio has been tested to exceed prolonged UV and salt fog exposure requirements. Few, if any, other brands talk about the durability of the overall design. Rockford Fosgate punishes their Element Ready™ products with impact and vibration testing to ensure you’ll always have tunes when on the trails or ripping the waves.

Whether on the water or the trails, the Element Ready™ PMX-1 is ready for anything you can throw its way.

User Interface Design

The first feature you will see when you look at the PMX-1 is its 2.3-inch dot-matrix monochrome display. While this looks simple, the display is constructed with a wet-bonded process that makes it easy to read in bright sunlight. The glass screen over the display has a 9H hardness rating, so it’s scratch-resistant. Many competing products use plastic over the display.

A sizable rotary encoder in the center of the front panel allows for volume adjustments or navigating through different menu settings. Four buttons on either side of the encoder provide direct access to source selection, track adjustment, play/pause, menu access, and a dimmer control. Bass heads will love that there are subwoofer + and – buttons on the front panel.

The layout of the front panel is intuitive and organized. Importantly, it’s durable.

Rockford Fosgate PMX-1 Source Options

You have four options for playing music from the PMX-1. The built-in terrestrial radio tuner includes AM and FM reception capabilities. It also has a weather band tuner for those near larger lakes or the ocean.

You can connect a 32GB or smaller USB memory stick to the USB port to play MP3 or WMA files. The system supports up to 255 folders with a maximum of 1,000 songs.

The radio has stereo RCA input jacks on the back as a third option. So, if you want your installer to connect it to a laptop, DVD player, or similar device, it’s ready to go.

Finally, the PMX-1 includes a Bluetooth receiver. The system uses Bluetooth 3.0+EDR and supports the Advanced Audio Distribution Profile (A2DP) version 1.3. You can connect almost any smartphone and play music stored on it or stream audio from Pandora, iHeartRadio, or Spotify. Album and artist information will scroll across the screen if your device supports sending this information over Bluetooth.

Power, Preamp, and Installation Considerations

The radio includes a four-channel amplifier rated to produce 25 watts of continuous power into four four-ohm speakers with less than 1% THD+N. It also has two sets of RCA jacks on pigtails, rated to produce up to 2 volts of output.

The radio includes a three-zone crossover set to high or low-pass modes with 60, 80, or 120 hertz filter frequencies. The crossovers work on the built-in amplifier and the preamp signals. For the second set of RCA outputs, your installer can select between the rear and subwoofer output functions in a nearby menu.

The radio has a seven-band graphic equalizer with Flat, Rock, Classic, Acoustic, Dance, Electronic, and Hip-Hop presets. A custom EQ mode allows you to fine-tune the system to suit your audio system design or listening preferences. Of course, Rockford Fosgate includes their famous Punch EQ in the PMX-1. You can dial up to 18 dB of boost at 45 Hz and 12 dB at 12.5 kHz.

Power conservation can be a concern for marine and powersports vehicles, so the PMX-1 includes a battery voltage display, so you can keep track of things. The radio uses non-volatile memory to store all setting information. As such, it only requires an accessory and ground power connection. There is no clock, so your installer doesn’t have to hook up a wire likely to drain the vehicle battery. If you turn the radio off but leave it powered, it draws under two amps of current. At the other end of the spectrum, the radio has a 20-amp fuse, so ensure your installer uses large enough wiring to power it.

The PMX-1 was designed with a 12-pin Molex connector for speaker and power connections.

Compact and Durable Audio Solution

If you are looking for a reliable, easy-to-use radio for a boat, side-by-side, ATV, or jet ski, the Rockford Fosgate PMX-1 is an excellent solution. If you’ve had a craving to build a portable boombox from an old ammo can, the PMX-1 is perfect for that as well. You can pick up a PMX-1 at any authorized Rockford Fosgate dealer. You can find a dealer near you using the locator tool on their website. Be sure to follow our friends from Tempe on Facebook, Instagram, and YouTube to keep up with new product releases and the events they attend.

Revisiting The Rockford Fosgate T500-1bdCP Review

T500-1bdCP Review

In January of 2024, we had the privilege of reviewing the Rockford Fosgate T500-1bdCP amplifier. Based on our experiences with amplifiers from the company, it was no surprise that the amp sounded amazing, was impressively efficient, and exceeded all of its power ratings. The latter is the focus of the re-test. We’ve recently upgraded the power supplies in the BestCarAudio.com Test Drive Review lab. As such, we can supply the subjects with a full 14.4 volts to provide you with measurement numbers that comply with the ANSI/CTA-2006-D standard. So, let’s have another quick look at the highlights of this impressive amplifier, then dig into some new power measurements and efficiency calculations.

Rockford Fosgate T500-1bdCP Features

Here’s what you need to know without going into the same detail as the original Rockford Fosgate T500-1bdCP Review. Firstly, this is a dedicated subwoofer amplifier. It has an as-measured -3dB frequency response of 4.4 to 230 hertz. That bottom-end extension is pretty impressive.

The amp is rated to produce 300 watts of power when connected to a four-ohm load and 500 watts to two- and one-ohm loads. There are amplifiers that produce more power for less money. However, this amp also sounds fantastic. We measured an impressive 0.0213% THD+N at four ohms. Like many others, the amp didn’t fall on its face at lower impedances. Distortion numbers dropped to 0.0226% at two ohms and a still impressive 0.0294% when driving a one-ohm load. These measurements were taken at the ANSI/CTA-2006-D standard of 1-watt output. However, the graph you’ll see below shows the amp remains composed across the entire power output range.

Feature-wise, the amp includes an adjustable -24dB/octave low-pass filter that can be set anywhere between 35 and 250 hertz. It also has a selectable infrasonic filter fixed at 28 hertz with a -12dB/octave second-order slope. Lastly, and as you’d expect, the amp includes the Punch EQ control. Your installer can use this to dial in up to 18dB of boost at 45 hertz to add some extra slam to your audio system. The Punch EQ filter is nice and narrow, so turning it up doesn’t make your midbass sound terrible.

An essential feature of the amplifier that many overlook is its cast-aluminum heatsink. Unlike extruded designs, cast heatsinks offer significantly more surface area. When combined with expertly designed efficient circuitry, your amplifier will play longer without overheating. We tested the T500-1bdCP for over an hour at full power into a two-ohm load, and it never shut down. By comparison, we’ve had several amps go into thermal protection in under four minutes. Cast heatsinks are significantly more expensive to manufacture, but if you want to know why people are still using three-decade-old Rockford Fosgate gear, this is one of the reasons why. Think of it like comparing a Zippo lighter to a plastic BIC lighter. Both might light the candles on a cake, but only one is designed to last for your entire life.

Re-Testing the T500-1bdCP

The ANSI/CTA-2006-D Testing and Measurement Methods for In-Vehicle Audio Amplifiers standard has changed a bit from previous versions. Specifically related to continuous power testing, the sensitivity control should now be set to its minimum sensitivity setting. Looking at it from the opposite perspective, the amp should be set to make its maximum power from the highest amount of input signal. For the T500-1bdCP, that would be five volts, according to the owner’s manual. We’ll discuss why this matters in another article.

The next clarification is that the amp must be able to produce this power level for at least 15 seconds. Previous versions of the CTA-2006 standard required the amp to be capable of making this rated output for one minute. While the technician side of me thinks the longer the test, the better, one minute at full power is a long time. Many low-quality amplifiers would be close to overheating. Our testing runs for a little over 15 seconds, which makes it fully compliant with ANSI/CTA-2006-D.

Lastly is voltage. All the standards have stated that the primary continuous power rating be measured with the amplifier supplied with 14.4 volts with a tolerance of +0% to -5%. We fine-tune the adjustment on our new power supplies to be within a few hundredths of a volt of 14.4, which significantly exceeds the 13.68-volt minimum. When it comes to making power, more voltage is always better.

We set the T500-1bdCP up on the bench, turned the sensitivity and Punch EQ all the way, turned the infrasonic filter off, and set the crossover to its highest frequency. We started with the continuous four-ohm power test first. In the original review, we measured 334.9 watts at 1% THD+N with 14.47 volts. With the sensitivity control lower and, thus, less noise in the signal, we saw 339.1 watts at precisely 14.4 volts.

Next, we added our second bank of four-ohm load resistors to provide the amp with a two-ohm load. The original test showed 544.4 watts from 14.12 volts. In the new test at exactly 14.4 volts, the amp produced 583.4 watts. The observed additional 29.3 watts from 0.28 volts is impressive.

Finally, we get to the 1-ohm testing. The original test saw the amp produce 697 watts when fed with 13.9 volts. Now, with an extra half-volt on tap, we measured 766.2 watts. Ignoring the extra 69.2 watts, this means the amplifier produces 53.2% more power into a one-ohm load than it’s rated for. If you’ve ever wondered why the Power Series amplifiers seem to jam harder than they should, this is why.

T500-1bdCP Review

With this re-test, we are going to introduce a new way of presenting the power versus THD+N graph. Rather than having them in separate graphs, we’ve taken the time to overlay all the traces into a single chart. You can see how clean the amp is right from 100 milliwatts up to where it reaches clipping. The traces are color-coded to make things easy to compare. The red trace is the four-ohm measurement, the green shows the two-ohm performance, and the blue trace is the one-ohm information.

Interestingly, the amp isn’t plagued by noise at low power levels. This is another topic we will cover in a future article.

T500-1bdCP Review

Increased Efficiency

A secondary benefit of providing an amplifier with more voltage is, in this case, an improvement in efficiency. Based on the original power numbers and associated measurements, the amp was 86% at four ohms, 83% efficient at two ohms, and 63% efficient when driving a one-ohm load. Our new measurements show that these numbers have improved to 87%, 84%, and 74%, respectively. You can see these calculations in the power measurement chart above.

Improved efficiency is a big deal. First, it means the amp won’t heat up as quickly, translating to more playtime. Further, and what matters in the case of your vehicle, it means you get more output power from the limited power available from the charging system.

An Amazing Subwoofer Amplifier

The T500-1bdCP’s performance already blew us away. Having the chance to repeat the power tests with the proper supply voltage shows the value that Rockford Fosgate’s product presents. They could easily rate the amp capable of producing 750 watts into a one-ohm load. Even though they don’t, you now know it can.

If you are shopping for a subwoofer amp that sounds amazing and makes lots of clean power, drop by a local authorized Rockford Fosgate retailer and ask about the T500-1bdCP. You can find a dealer near you using the locator tool on their website. As always, follow the gang from Tempe on Facebook, Instagram, and YouTube to stay up to date with all their car, marine, powersport, and motorcycle audio product releases.

Revisiting the Rockford Fosgate R2-1200X1 Test Drive Review

R2-1200X1 Test

In late October 2023, we had the opportunity to give the Rockford Fosgate R2-1200X1 subwoofer amplifier a thorough Test Drive Review (https://www.bestcaraudio.com/test-drive-review-rockford-fosgate-r2-1200×1/). We were very impressed that this entry-level amp had features and performance that dramatically outperformed entry-level and mid-level products from other brands.

Power Testing and the Importance of Supply Voltage

The original test had one hiccup. When running a 1-ohm load, the amp produced 1,155.3 watts, which is a few watts (44.7) shy of the rated 1,200 watts the amp should produce.

Why did this happen? Is the R2-1200X1 not a real 1,200-watt amplifier? The answer lies in the power supplies we used to feed the amplifier. The supplies, a pair of Stinger SPS80 units, don’t have an output voltage adjustment. We’ve used their high- and low-voltage settings to show how different amplifiers perform at different supply voltage levels. The problem is, amplifiers tested to the ANSI/CTA-2006-D specification must be supplied with 14.4 volts. We only fed the R2-1200X1 13.61 volts. So, making just 44 watts shy of the rating, with 0.79 volt less than is expected, is actually impressive.

We typically explain that minute differences in output power are inaudible. The difference in output level between 1,155.2 and 1,200 watts is only 0.16 dB. You can’t hear that difference. Nevertheless, car audio enthusiasts want to see the largest numbers possible regarding power ratings … for some reason.

R2-1200X1 Test

New Power Supplies Fix Everything

After months of research, we have purchased two new 100-amp, 15-volt power supplies for the BestCarAudio.com test bench. The new supplies have an adjustable output, so we can fine-tune them to produce precisely 14.4 volts to ensure that the measurements we provide fully comply with the ANSI/CTA-2006-D specification. We use our QuantAsylum QA403 audio analyzer to measure harmonic distortion and noise and adjust the output level to be within a tenth of 1% THD+N.

Repeating the Rockford Fosgate R2-1200X1 Test

With the new supplies wired up and a few wires re-terminated, it was time to repeat the power measurements. As you can see from the chart below, the impressive R2-1200X1 does indeed produce every bit of power that Rockford Fosgate claims – and more. If you’ve been paying attention to the other products we’ve tested from them, that should be no surprise.

R2-1200X1 Test

We picked up 27.3 watts at 4 ohms, 36.5 watts at 2 ohms and an impressive 109.9 watts when driving a 1-ohm load.

Distortion Versus Output Graphs

While the amp was back on the bench, we generated THD+N versus power output graphs for each load. The graphs show total harmonic distortion and noise on the vertical scale and power output on the horizontal scale.

R2-1200X1 Test

R2-1200X1 Test

R2-1200X1 Test

Different amplifier designs have different characteristics regarding how they add harmonic distortion to the signal. The R2-1200X1 behaves well, with moderate THD+N increases as output levels rise. There’s nothing bad or unexpected in any of the measurements.

Why Does More Power Supply Voltage Increase Maximum Power Output?

Before we close, we should discuss why increasing the supply voltage increases an amplifier’s maximum power. In the case of this amp, the power supply is unregulated – or, at the very least, loosely regulated. In terms of practical explanation, the voltage supplied to the amp is multiplied by a fixed amount to create the rail voltages that drive the output.

If we had to guess, the R2-1200X2 takes the supply voltage and multiplies it by roughly 2.25. This gives us positive and negative rail voltages of approximately +32V and -32V. The audio signal can swing between these voltages, giving us just over 44.3 volts RMS available to drive the subwoofer. At 4 ohms, that’s just under 500 watts.

At lower impedances, the limiting factor in how much power the amp can produce is the power supply’s current delivery capabilities. We measured 41.4 volts into a 2-ohm load and 35.57 volts into a 1-ohm load. Once again, this is entirely normal behavior for a high-quality amplifier.

Check out the R2-1200X1 for Your Car Audio Subwoofers

If you’re shopping for an affordable subwoofer amplifier that sounds good, offers fantastic efficiency and includes all the features you need to make your car audio system sound great, drop by a local authorized Rockford Fosgate retailer and check out the R2-1200X1.

Product Spotlight: Rockford Fosgate M2-65 and M2-65B Marine Speakers

Rockford Fosgate M2-65

I remember when only one or two large car audio companies offered products designed specifically for marine applications. These days, there are dozens of brands in that market. From my extensive hands-on research, I can tell you that Rockford Fosgate is one of the brands you’ll want to check out for your boat. Their engineering-based marine speaker solutions are truly unique in the market. This Product Spotlight will examine the M2-Series M2-65 and M2-65B 6.5-inch Color Optix marine speakers.

Rockford Fosgate Marine Speaker Features

As is typical of Rockford Fosgate, they offer diverse speaker solutions to suit every application and budget. The Marine series starts with the affordable M0 line, which features white or black 6.5-inch coaxial drivers. From there, you step up to the M1 line, adding 6-, 6.5- and 8-inch drivers with Color Optix integrated RGB LED lighting. These speakers can handle even more power so that they can play louder. At the top of the marine speaker series are the M2 speakers. In this line, you have 6.5-, 8- and 10-inch coaxial drivers, with the two larger offerings available with a conventional tweeter or a small compression horn.

The M2-65 and M2-65B speakers are 6.5-inch coaxial drivers with your choice of white or black (the B at the end of the part number) grilles. The speaker system includes two drivers, stainless-steel grille inserts, mounting hardware and speaker wire pigtails with high-quality Deutsch connectors.

They are rated to handle 150 watts of power continuously with peaks of 300 watts. Efficiency is specified as 91.8 dB at 1 watt/1 meter. The drivers have a nominal impedance of 4 ohms and require 2.49 inches of mounting depth in a 5.36-inch cutout in your boat.

Speaker Component Features

The mineral-filled polypropylene woofer cones feature a co-molded thermoplastic elastomer synthetic rubber surround. The surround uses the Vertical Attach Surround Technique mounting geometry where it attaches to the chassis. This feature increases cone area, which improves sensitivity and bass output. A 1-inch diameter, high-temperature Kapton voice coil former is at the base of the cone. The large diameter of the voice coil is the key reason these speakers are rated to handle 150 watts of power continuously. A linear aramid-polyester spider provides good cone control and high excursion levels. The tinsel leads, attached to gold-plated brass terminals in the chassis, are encased in rubber to protect them from water damage.

The 1-inch tweeter in the speaker’s center features a design that Rockford Fosgate calls PXNX. It uses a pair of compact neodymium slugs for excellent efficiency.

Element Ready Design Ensures Reliable Performance

Rockford Fosgate doesn’t pull any punches when it comes to ensuring that their marine audio products can withstand whatever Mother Nature throws their way. Their Element Ready design covers water resistance and UV and salt exposure. In terms of waterproofing, these speakers carry an IPX6 rating. Ultraviolet exposure testing passes the ASTM G154 500-hour accelerated UV test. Salt exposure is evaluated using the ASTM B117 500-hour salt-fog test. Finally, many marine and powersports speaker manufacturers overlook vibration and impact testing. Rockford Fosgate uses the ISO60068-2-64 Vibration testing standard to ensure that the speakers can take a beating as your boat hits even the gnarliest waves. Rockford Fosgate backs the M2 speakers with a two-year warranty against manufacturing defects.

Product Spotlight: Rockford Fosgate M2D2-10I and M2D4-10I Marine Subwoofers

Rockford Fosgate M2D2-10I

When choosing subwoofers for a boat audio system, having the correct drivers for the application is crucial to designing a system that sounds good and will last for years. The marine audio fanatics at Rockford Fosgate have a subwoofer solution for every application. We will examine the 10-inch M2-Series M2D2-10I and M2D4-10I subwoofers in this spotlight.

Subwoofer Solutions for Every Application

Before we discuss the M2D2-10I and M2D4-10I subwoofers, we should discuss all available options. The M2-Series includes subwoofers for relatively small sealed or ported enclosures and the I-series for infinite baffle applications. You can choose from 10- or 12-inch woofers with dual 2- or dual 4-ohm voice coils. You can also choose from black or white “sport” grilles. All 16 different M2-Series subwoofers also include a stainless-steel grille insert so you can pick your style before installation.

The M2D2-10I is a 10-inch subwoofer with a white grille and dual 2-ohm voice coils. Its brother is the M2D4-10I, which has dual 4-ohm coils. The same drivers are available with black grilles in the M2D2-10IB and M2D4-10IB.

You can choose black or white grilles with either dual 2-ohm or 4-ohm voice coils in the 10-inch M2-Series marine subwoofers.

10-inch Infinite Baffle Subwoofer Specifications

The Rockford Fosgate M2D2-10I and M2D4-10I are rated to handle 400 watts of continuous power with peak power rated at 1,600 watts. The drivers have an efficiency of 90.3 dB and an Xmax specification of 11 millimeters of excursion in each direction. These subwoofers have a stiff aramid-polyester spider with a linear rate to control cone motion without an enclosure. The result is a driver that plays loudly without concerns about the woofer cone bottoming out.

Marine Subwoofer Features

These subwoofers are based around a 30% fiberglass-reinforced PA66 nylon basket. The mixture includes UV inhibitors, so the plastics won’t chalk, fade, crack or discolor when exposed to the sun. The electrical connections are made via Deutsch/Amphenol connectors with gold-plated brass terminals molded into the basket. The basket also has integrated cooling vents protected with nano-coated mesh to keep water out.

The woofer cone is made from mineral-filled polypropylene. The mineral powder adds thermal stability and improves the damping characteristics. A large 2-inch Kapton voice coil serves as the heart of the subwoofer. The tinsel leads from the voice coil to the terminals are encased in silicone to protect them from damage. Rockford Fosgate includes a VERSA switch that lets your installer quickly select between series and parallel wiring to simplify the installation. For dual 2-ohm models, the VERSA switch allows you to select between 1-ohm (parallel) or 4-ohm (series). On dual 4-ohm models, you can select 2-ohm or 8-ohm.

Rockford Fosgate M2D2-10I
The VERSA switch allows your installer to select series or parallel wiring to speed up installation.

The top of the cone is bonded to a UV-stable, injection-molded foam surround. The surround mounts vertically to the edge of the basket. Rockford Fosgate calls this their Vertical Attach Surround Technique, a design that increases the effective cone area while maintaining standard mounting dimensions. The effective surface area of the M2D2-10I subwoofer is 363 square centimeters or 56.72 square inches. Popular competing products have 320 to 340 square centimeters. When it comes to optimizing efficiency, cone area matters.

Designed for Durability

The Rockford Fosgate engineering team takes reliability seriously. Their marine speakers and subwoofers pass torture tests to earn their Element Ready label. These include 500 hours of accelerated UV and salt fog testing, an IPX6 water intrusion rating and durability testing that meets the ISO60068-2-64 standard. A two-year warranty backs the M2-Series marine subwoofers against manufacturing defects.

Color Optix Integrated Lighting

Nobody can think of a wakeboard boat without thinking about style. As mentioned, you can choose from white or black sport grilles and decide whether you want the stainless inserts installed. Rockford Fosgate has integrated RGB LED lighting under the grille in a design they call Color Optix to take things a step further. You can choose from thousands of illumination colors using the RF Connect smartphone app with the optional PMX-RGB lighting controller. You can also configure color-shifting patterns if you want. Of course, the wiring for the lighting, along with the circuit boards, also meets the Element Ready requirements.

Infinite Baffle Installation Simplicity

We should clarify the definition of an “infinite baffle” subwoofer installation. This refers to mounting the subwoofer in a location where the sound coming from the back of the driver can’t mix with the sound from the front. In short, it’s like mounting the subwoofer in a wall that extends forever. In a boat, a storage locker under a seat is one of the most common installation locations. Many infinite baffle subwoofers are mounted in the podium in a center-console boat.
