Product Spotlight: Compustar Q9 with LTE Remote Starter

Compustar Q9

Two-way remote car starters and security systems help to ensure that you always know what’s happening with your car or truck. Remote controls that include an LCD screen make it quick and easy to know whether the doors are locked or the engine is running. Compustar’s Q9 remote kit consists of a two-way LCD remote and their DroneMobile X1-LTE telematics interface to provide a complete control-from-anywhere remote starter or security solution for your vehicle.

What Is the Compustar Q9 with LTE Kit?

The Q9 remote and DroneMobile kit is known formally as the RFX-2WQ9-FM. It includes a two-way LCD remote and the DroneMobile X1-LTE interface. The remote features five control buttons to make locking, unlocking, remote start and trunk release functions instantly and intuitively accessible. The centrally located Engine Start/Stop button on the Q9 mimics the lock, unlock and remote start functions of a Compustar one-button remote. You can also access two auxiliary outputs to control power sliding doors on a minivan or hatch release on an SUV. The LCD screen has dedicated icons that display the door lock status and indicate whether the doors are open or the engine is running. If you opt for a temperature sensor when the Q9 is installed, you can also check the temperature in the vehicle.

Compustar sells its remote packages separate from its control modules, so the retailer you’re working with can pair the Q9 kit with a remote starter, security system or a hybrid unit that offers all the features you want. The Q9 remote is bundled in the CSX2WQ900-A security system with DroneMobile and the CS2WQ900-AS remote starter and security system.

The RF transceiver in the Q9 remote provides up to 3,000 feet of range to let you control your vehicle from inside a small apartment or a medium-sized office building. This is enough communication range to let you keep tabs on your vehicle and remote start it without going outside. Factory-installed keyless entry systems don’t provide this much range.

Control from Anywhere with DroneMobile

The Q9 remote kit includes the DroneMobile X1-LTE telematics system. DroneMobile consists of a communication interface that connects to your vehicle’s Compustar remote starter or security controller. The interface uses cell phone communication towers to relay commands from your smartphone to the vehicle and back. If you want to remote start your car or truck, launch the app on your phone and press the start button for a few seconds. The starting message from the app will travel through the internet and the cellular provider to the vehicle in a few seconds. Best of all, once the vehicle is running, you’ll get confirmation on your phone. There are no range limitations with Drone. You can be at home, at work or on vacation in Mexico – as long as you have internet access, you have control. If you have the FT-DAS-II sensor in your vehicle, the DroneMobile system also relays security alerts to your smartphone.

With a DroneMobile Premium service plan, you can also use the X1-LTE’s built-in GPS receiver to pinpoint the location of your car or truck. You can set location-based geofence or time-based alerts to keep tabs on your vehicle.

Product Spotlight: Rockford Fosgate P1/P2/P3-2X12 Loaded Subwoofer Enclosures

Rockford Fosgate Enclosures

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.

Robust MDF construction with reinforced corner joints ensures reliable performance.

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.

A terminal cup on the left-side end panel makes it easy for your installer to connect the enclosure 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.

Passive Vs Active Crossover Networks

Crossover NetworksTo optimize the performance capabilities of a speaker, it should operate within the frequency range for which it was designed. A woofer or subwoofer won’t be able to reproduce high frequencies accurately. A tweeter will self-destruct if you ask it to try to play bass frequencies. For this reason, we use three- and four-way speaker systems in most vehicles. That means using crossover networks.

The purpose of a crossover is to split up the frequencies that pass through it. We are going to delve waist-deep into the benefits and drawbacks of the crossovers commonly used in car audio system component speaker sets.

How a Passive Crossover Network Works

Crossover Networks
This inductor is one of the pieces used in a passive network

A passive crossover network is a component or group of components that is installed on the speaker wires between an amplifier and a speaker. The behavior of these components attenuates portions of the signal going to the speaker itself. Four components are commonly used in passive networks: capacitors, inductors, resistors and protection devices.

The combination and configuration of these components are used to create a low-pass, high-pass or band-pass filter network. Resistors are used to attenuate the output of devices, or sometimes used as part of a frequency-dependent impedance correction circuit called a Zobel network. Some manufacturers include light bulbs, diodes or some form of positive temperature resistors to limit how much voltage a tweeter receives. Completely passive active networks have been available (but that was a long time ago).

How an Active Crossover Functions

Crossover NetworksAn active crossover is a device that modifies an audio signal before the amplifier. It works on line-level or preamp signals only. Active crossovers combine op-amps, resistors and capacitors to alter different frequency ranges of the signal. Unlike passive networks, active crossovers can be designed to increase the level of the signal, but only in the case of powered filters. Active networks are often include other functions, such as remote level controls and bass boost circuits.

Benefits of Passive Crossovers

Crossover Networks
The switches on this passive crossover allow for attenuation.

It is worth noting that each passive network is designed to work at a specific frequency for a specific speaker. If you change the speaker, the filter will not respond in the same way. In some cases, if the impedance of the speaker is significantly different from the one the network was designed for, the speaker may be damaged, or portions of the network may become damaged.

Passive networks are easy to use. You run a wire from your amplifier to the input of the network, then connect each speaker to the output. Other than mounting the network in a dry location that is free from vibration, that’s about all you have to consider.

Some passive networks include some form of output level attenuation. Most use a two- or three-position switch. Some use jumpers. An extremely high-end network may include a variable L-pad or potentiometer for extreme fine-tuning capabilities.

Passive crossovers allow you to split the power of a single amplifier channel to drive two different speakers. Fewer amplifier channels can dramatically reduce the system cost, since you only need a pair of amplifier channels to run a full set of speakers.

Limitations of Passive Crossovers

Since a passive crossover network is designed for a specific frequency, once the parts are chosen and assembled, there is no way to change that frequency without introducing new or additional parts.

Designing a passive crossover can be somewhat complex. The simplest of networks rely on some basic assumptions about the impedance of each speaker at the crossover frequency. Designing a network that compensates for the complex reactive load that speakers create as they move is difficult. It requires computerized modeling software and a way to measure the impedance and frequency response of the speaker at varying drive levels.

High-quality passive crossovers are designed for a specific distance and angle between the woofer and the tweeter. If the network is designed for the speakers to be far apart, moving the speakers close together will cause the signals to sum incorrectly. Even changing the angle of a speaker can have a dramatic effect on the frequency response at the crossover point.

Passive crossover networks have limitations in how much power they can handle. The magnetic fields created in an inductor have a limit. The voltage applied to a capacitor also has a limit. Crossover networks can and do overheat and fail if too much power is sent to them.

Passive crossover networks consume energy. Using a speaker system with a passive network is not quite as efficient as one using an active filter network. The overall efficiency of the crossover network depends on its complexity and the quality of the components used in the network.

Passive crossover networks are somewhat susceptible to noise. If you run a wire with an AC signal on it past the inductor in a passive network, the network can easily pick up that signal and add it to the audio signal. Choosing a safe location to mount passive crossover networks is important.

Benefits of Active Crossovers

Crossover NetworksMost active crossover networks are adjustable. That means by turning a knob or moving a switch, you can change the crossover frequency. This flexibility makes active crossovers suitable for use with almost any speaker system. Most active crossovers also include level controls, so you can easily fine-tune the level of the midrange and tweeter to compensate for different mounting locations.

Active crossovers don’t care how powerful your amplifiers are because they process the signal before it enters the amplifier. Active crossovers are also not very sensitive to temperature variations, so they can be very accurate, all the time. If one of the amplifiers channels in an active crossover system clips, the distortion only affects that single channel.

Challenges of Active Crossovers

Because active crossovers are universal in design, being able to set crossover frequencies accurately can be challenging. Labels on potentiometers are notoriously inaccurate. Most active crossovers have fixed attenuation slopes. You can’t change these slopes to compensate for response characteristics or placement variations. Unless the speaker manufacturer provides it, or you have extensive experience in measuring the electro-mechanical and acoustic response of the set of speakers, knowing what frequency to cross speakers over at can be difficult. Too low and you risk damage to the tweeter. Too high and you get distortion from the midrange. Many speaker combinations also require the over- or under-lap of the crossover frequencies to produce a flat response.

An active crossover requires a dedicated amplifier channel for each speaker. These extra channel requirements can increase the cost of designing a system.

The Perfect Solution

Crossover NetworksIf there is no limit to your budget, the ideal crossover solution for a set of speakers is an active crossover with a Digital Sound Processor performing the filtering. A DSP will offer adjustable crossover frequencies, and most offer adjustable crossover slopes and alignments.

No matter what you choose, it’s a good idea to spend some time with a high-resolution RTA to make sure your system is set up for the smoothest, flattest response possible at the crossover frequency.

Product Spotlight: Rockford Fosgate P1650 and P1694

Rockford Fosgate Speakers

Would you think it was possible to pack a whole slew of technologies into a pair of car audio speakers? For the fanatics at Rockford Fosgate, that tech translates to more output and better sound in your vehicle. In this product spotlight, we’ll take a deep dive into the Punch Series P1650 6.5-inch and the P1694 6×9-inch sets.

Rockford Fosgate P1650 Speakers

Rockford Fosgate Speakers

Perhaps the most popular speaker size today is the 6.5-inch coaxial. This size fits into hundreds of models of cars and trucks. The Punch Series P1650 set includes a pair of coaxial speakers that feature mineral-filled, injection-molded polypropylene woofer cones and ¾-inch treated PEI dome tweeters. The addition of minerals like mica helps damp resonances to reduce distortion while improving the thermal stability of the cones.

The cone is attached to the basket with a Santoprene rubber surround that will outlast conventional foam designs. The P1650 drivers use the Vertical Attach Surround Method (VAST) to increase the effective radiating area of the driver for more efficiency and bass output. To ensure smooth frequency response, the P1650 set uses -12 dB/octave crossovers concealed within the basket. Rockford Fosgate calls this its Integrated Concealed Crossover (ICC) design. In addition to being neat and tidy, there are no extra modules (external crossover enclosures) for your installer to deal with, so the installation will be quick and efficient.

Choosing speakers that fit your vehicle is as important as selecting ones that sound great. The P1650 speakers feature the FlexFit2 stamped basket design. This design provides eight mounting holes and eight elongated slots to ensure that the speaker can fit a variety of vehicle OEM mounting points. The mounting depth is specified at 2.24 inches. A set of steel mesh grilles is also included.

Wrapping up the specs on these drivers, we have a continuous power handling rating of 55 watts and a max rating of 110 watts. Their nominal impedance is 4 ohms, and they have a sensitivity rating of 88 dB SPL at 1 watt at 1 meter. Sensitivity at this level typically indicates that the suspension design is optimized for sound quality.

If you have a car or truck with 6×9 speaker locations in the doors or rear parcel shelf and you want to rock out, the four-way P1694 6×9 set is the perfect option. Once again, these speakers include the same mineral-doped polypropylene woofer material as their little brothers and use the VAST surround design for optimized efficiency. These drivers feature a pair of PEI dome tweeters that flank a compact titanium composite cone midrange driver that also includes a rubber surround.

The mounting depth on the P1694 speakers is 3.07 inches, and the drivers include steel mesh grilles and mounting hardware. They can handle 75 watts of power continuously and peaks of 150 watts. Their nominal impedance is 4 ohms, and they have an impressive 91 dB SPL 1W/1M efficiency rating.

It’s worth noting that all of Rockford Fosgate’s speaker and subwoofer specifications fully comply with the CTA-2031 standard for the Testing and Measurement of Mobile Loudspeaker Systems. What does this mean? The dimensions are accurate, and the specifications are entirely believable and uninflated. Not all car audio brands can make this statement.
