When it comes to subwoofer amplifiers from Rockford Fosgate, a few models stand out in the annals of car audio history: the Power 1000, the Power T15kW and the T2500-1bdCP. The latter is currently the flagship of the Power Series and is the most powerful subwoofer amplifier available from our friends in Tempe, Arizona. It’s a workhorse capable of impressive performance, so let’s check it out!

Rockford Fosgate T2500-1bdCP Features

The T2500-1bdCP is a 2,500-watt subwoofer amplifier. It’s based on a large cast aluminum heatsink with a footprint of 8.14 inches in depth, 21.875 inches in width and a total height of 2.14 inches. All the power, signal and subwoofer connections are made along the front edge of the amplifier. A pair of massive 0-AWG terminals on the right side connect the amp to your battery bank, and two pair of speaker terminals on the left side will accept up to 8-AWG speaker wires.

The center panel on top of the amplifier is home to a pair of LED-based level meters. The left-hand meter shows output power in 11 steps from idle to +2 dB (well into clipping). The right-hand meter displays battery voltage from 9 to 16 volts in 11 steps.

In the center of the side panel are the configuration controls. The amp will accept up to 4 volts of input on the RCA terminals. Of course, Rockford Fosgate has included balanced differential inputs on the RCA jacks to eliminate noise that might have been picked up by the RCA interconnects. The low-pass crossover is non-defeatable and offers -24 dB/octave attenuation with frequencies adjustable between 35 and 250 hertz. A selectable infrasonic filter applies a high-pass filter to the audio signal with a 12 dB/octave filter set to 28 hertz.

Of course, the amp includes the famous Punch EQ circuit that allows your installer to dial in up to 18 dB of boost at 45 hertz. An optional Remote PEQ module can be added to let the driver adjust the Punch EQ circuit from the front of the vehicle.

The amp features Rockford Fosgate’s BD output configuration that delivers excellent efficiency and sound quality. The Constant Power design helps ensure that the amp makes as much power as possible into various load impedances.

T2500-1bdCP Power Ratings

In terms of power production capabilities, the T2500-1bdCP is rated to produce 1,500 watts of output into a 4-ohm load and 2,500 watts into 2- and 1-ohm loads. Given our lab experience with Rockford Fosgate products, these numbers are likely underrated by about 10%.

If that’s not enough, two of these amps can be strapped together using the optional bdSYNC2 cable to deliver 5,000 watts of power into a 4- or 2-ohm load. Voice coils, be warned! The amp also has a MasterSync mode that allows a single unit to drive an array of similar amplifiers with the same configuration settings. The RCA output jacks on the right side of the side panel are fundamental to making these features function. Uniquely, your installer can combine the bdSync and Master Sync modes to drive two subwoofers with 5,000 watts each using four amplifiers.

Smart car audio system designers will know that all amplifiers decrease in efficiency with decreases in load impedance. Rockford Fosgate rates the T2500-1bdCP as being 81.9% efficient at 4 ohms, 77.7% efficient at 2 ohms and 64.5% efficient when connected to a 1-ohm load. If you want to get the most bang for your buck in terms of battery and alternator capacity, a 2-ohm load makes these amps the happiest.

By way of sound quality specifications, Rockford Fosgate rates the amp as having a signal-to-noise ratio of at least 70 dB at a 1-watt output level. This is impressive for an amplifier with this much signal gain and capable of so much power. As with all amplifiers from Rockford Fosgate, all specifications comply with the ANSI/CTA-2006-C standard for car audio amplifier specifications.

You’ll find thousands of options when choosing upgraded speakers for your car audio system. Rockford Fosgate’s Power Series fits the bill perfectly for those looking for a solution that delivers great sound quality with impressive efficiency and output capability. In this spotlight, we’ll look at the T1650 and the T1693 speakers – two of the most popular sizes in the series.

Rockford Fosgate Power Series Features

The T1650 is a two-way 6.5-inch class speaker optimized for installation in North American, European and Asian vehicles, thanks to its FlexFit 2 basket design. The T1693 is a three-way 6×9 speaker that works in almost any application with at least 3.43 inches of mounting depth.

Both drivers are based on a sturdy stamp-cast aluminum frame. The woofer cones are made of carbon fiber-reinforced polypropylene to deliver excellent rigidity and thermal stability balance. The outer edge of the woofer cone is attached to the basket using a Santoprene rubber surround. The T1650 features Rockford Fosgate’s Vertical Attach Surround Technique design that optimizes the effective cone area of the woofer to increase bass output and efficiency.

At the base of the woofer cones are aluminum voice coil formers that help to draw heat away from the winding. The T1650 has a 1.1-inch voice coil former, and the T1693 features a 1.2-inch diameter former design for added power handling. Vents in the basket under the spider mounting ledge allow hot air to escape from the voice coil. These vents also improve linearity at high excursion levels. Finally, fatigue- and tear-resistant poly-cotton spiders return the woofer cones to rest once the audio signal stops.

The tweeters in the speakers feature a treated aluminum dome design for excellent power handling and high-frequency extension. The tweeter on the T1650 is mounted on a bridge that suspends it above the woofer. This design eliminates the need for a pole piece through the center of the woofer and further increases the radiating area of the woofer. Both drivers feature Rockford Fosgate’s Integrated Concealed Crossover design that hides the filter network within the basket to protect the components and simplify the installation process.

Both systems include a pair of speakers, a set of steel mesh protective grilles and mounting hardware.

Rockford Fosgate T1650 Specifications

The T1650 has a continuous power handling rating of 75 watts and can handle up to 150 watts of peak power. The driver has a nominal impedance of 4 ohms, and its efficiency is specified as 88 dB when powered with 1 watt and measured at 1 meter. A moderately high Qts specification of 0.73 will give the driver a little extra warmth in the lower midrange, making it a perfect solution as a stand-alone option or for use in an audio system with a subwoofer.

Rockford Fosgate T1693 Specifications

The T1693 is a three-way 6×9 speaker with a 1-inch aluminum-dome tweeter and a ½-inch super tweeter. The driver has a nominal 4-ohm impedance and a rated efficiency of 91 dB at 1 watt/1 meter. Power handling is specified as 100 watts continuous and 200 watts peak. The Qts value of 0.6 still delivers a slightly warm sound but emphasizes the focus on excellent dynamics in the lower midrange.

All the dimensional and performance specifications provided for these speakers are compliant with the ANSI/CTA-2031-A standard for the Testing and Measurement of In-Vehicle Loudspeaker Systems. This means you can trust the provided information to be accurate and truthful. It’s also worth noting that Rockford Fosgate uses Klippel speaker analysis equipment to optimize the design of their loudspeakers and subwoofers to ensure that they operate linearly and deliver excellent sound quality.

Few upgrades make a more noticeable change or add more fun to your car audio system than adding a subwoofer system. The car audio fanatics at Rockford Fosgate have made it easy to choose a performance level with their P1, P2 and P3 dual 12-inch 2X12 Loaded Punch Series subwoofer enclosures. Let’s dig into what makes these bass upgrades deliver some of the best bang for the buck on the market.

Custom Enclosure Designed for Car Audio Systems

If you look back at our Test Drive Review of the P500-12P, you might remember that the folks at Rockford Fosgate have a unique approach to car audio subwoofer enclosure design. While most companies perform simulations exclusively in software, the product development team at Rockford Fosgate designs their enclosures to work with the acoustics of the vehicle. This results in physically smaller enclosure designs that offer impressive efficiency and extension without taking up vast amounts of space.

The footprint of the 2X12 series enclosures measures 33.875 by 15.75 inches. To optimize space, the angled rear panel fits up snugly against the rear seats in a coupe, hatchback or SUV. The enclosures are 15.125 inches tall, so they won’t block the view out of the back of your vehicle.

The cabinets are constructed from 5/8-inch MDF with inset side panels. They are finished in a durable high-density black carpet. The front panel features a large-surface-area vent optimized to prevent noise at high volume levels. A custom-tooled trim panel over the vent looks cool and keeps loose objects from entering the enclosure. A set of chromed spring-loaded binding posts on the left side end panel will accept 10-AWG wiring and make it easy to connect the subwoofer system to your amplifier.

Given that the Thiele/Small parameters of the P1, P2 and P3 Punch Series subwoofers are similar, the enclosure options offer similar overall tonal balance but with ever-increasing output capabilities.

Pick Your Poison: Mild to Wild Bass

Rockford Fosgate offers their 2X12-Series enclosures with your choice of Punch Series P1, P2 or P3 drivers. The P1-2X12 includes a pair of P1S4-12 subwoofers, each rated to handle 250 watts of power continuously and 500 watts maximum. Each driver has an Xmax spec of 9 mm, which is good for an affordable subwoofer solution. The system has a net load impedance of 2 ohms and weighs 70.9 pounds. Rockford Fosgate recommends the P300X1 as a great power solution for this enclosure.

If you want more output, step up to the P2-2X12, with its pair of P2D4-12 subwoofers. These subs can handle 300 watts continuously or 600 watts each. The P2 subwoofers have a one-way Xmax spec of 13.3 mm, so this will play louder if you feed it more power. The pair of dual-voice-coil drivers is wired to a net 1-ohm load. The P2-2X12 enclosure weighs in at 77.35 pounds. The P500X1 is suggested as a perfect match for this enclosure. The Punch P2 subwoofers use Rockford Fosgate Vertical Attach Surround Technique (VAST) to optimize cone area. The P2 and P3 12-inch subs have 4% more effective cone area than the P1 drivers.

Rockford Fosgate offers the P3-2X12, which includes a pair of P3D4-12 12-inch subs for the most jam from this enclosure design. These drivers are rated to handle 600 watts continuously or 1,200 watts maximum power per driver. They have an Xmax specification of 15.9 millimeters and are wired to present a 1-ohm load. Paired with an amplifier like the P1000X1bd, this enclosure will shake your behind and rattle your fillings. The P3-2X13 weighs a hefty 89.65 pounds, so you’ll want to get some help if you have to remove it from your vehicle.

You can pair these enclosures with Prime series amplifiers if you’re on a budget or Power series amplifiers if you want improved clarity and detail. Your local Rockford Fosgate retailer can help you create a package that will deliver the performance you want. Use the dealer locator on their website to find a shop near you. Of course, follow the Rockford Fosgate team on Facebook and Instagram to learn about their latest product releases. Also, check out the videos they post on YouTube; they are truly impressive!
