It isn’t hard to notice that AudioControl hasn’t eased up on its delivery of amazing new mobile audio product solutions. The latest addition to the AudioControl family is the high-power LC-1.1500 subwoofer amplifier. Rated to produce 1,500 watts of continuous power and equipped with the integration and audio processing features you’ve come to expect from AudioControl, this new monoblock is sure to be a huge hit!
AudioControl LC-1.1500 Design
The LC-1.1500 shares the same cast aluminum heat sink as the LC-6.1200 with a total length of 12 inches. All of the connections are on the front edge of the amplifier, including the beefy 0-AWG power block and a hefty 8-AWG speaker terminal block. There are two positive and two negative speaker output terminals to facilitate connections to multiple subwoofers or multiple voice coils.
The left side of the end panel features no less than four 40-Amp ATC fuses. The center of the panel is home to the input connections. Your installer can choose from a pair of line-level RCA jacks or connect the amp to a factory-installed source unit or amplifier using the provided speaker-level input terminals. It’s well worth noting that the LC-1.1500 will accept speaker-level signals up to 40 volts RMS. This high-voltage compatibility eliminates the need for an external line-level converter. Last but certainly not least, an RJ-11 jack serves as the connection for the optional ACR-1 remote level control.
Audio Processing Features
It should come as no surprise that signal processing has always been one of AudioControl’s strengths. Starting with the basics, the 1.1500 includes an adjustable -24dB/octave electronic crossover with a Linkwitz-Riley alignment. The crossover is adjustable from 30 to 230 Hz. Beside the crossover is the amplifier sensitivity control. When using the line-level inputs, the amp will produce full power with an input signal between 500mV and 6 volts. When using the speaker-level inputs, the input voltage range increases from 3V to 40V. Input and output level optimization LEDs are included to increase the efficiency and accuracy of the level-setting process.
The 1.1500 includes AudioControl’s GTO (Great Turn On) signal sensing circuit. If you have the LC-1.1500 connected to a factory-installed radio or amplifier, this circuit will turn the 1.1500 on automatically when you start playing music.
Speaking of factory audio integration, the 1.1500 also includes the AccuBASS processing feature. This feature helps to restore low-frequency information that is often limited in factory-installed audio systems. Your installer can set the input threshold level and decide just how much extra output is required to restore impact and excitement to your music.
Amplifier Design
A look under the top cover of the AudioControl LC-1.1500 reveals a massive power transformer flanked by two large banks of filtering and stiffening caps. The output from the Class D circuitry features two large toroidal filters and two large caps. An internal shield keeps RF emissions away from the signal processing circuitry for improved sound quality. All the caps and transformers are secured in place with silicone to prevent damage from vibration. The majority of the signal processing and control components on the board are high-tolerance surface-mount devices.
A compact cooling fan in the center of the circuit board helps to circulate air across the heat sink and reduce the chances of thermal overload. AudioControl includes a microcontroller in the amp that monitors the system performance and can protect the amp if a short circuit, thermal overload or power supply voltage issue occurs. The Protection LED flashes a code that you can look up in the owner’s manual, so you’ll know what’s happening. The microcontroller also controls the fan speed.
Big Bass with Big Features
The 1.1500 is rated to produce 850 watts of power into a 4-ohm load and 1,500 watts into a 2-ohm load. The S/N ratio specifcation of -102 dBA referenced to full power and the bandwidth is 24Hz to 230Hz with the crossover at its maximum frequency. A 24dB/octave infrasonic filter that AudioControl calls the PFM Subsonic filter protects your vented subwoofer systems from damage.
This amplifier isn’t for the meek. If you are serious about big bass in your car, truck or SUV and you have the subwoofers to handle this sort of fun, this is an amazing option. You’ll need to be sure to feed the amp with proper wiring (0 AWG). With the ability to draw over 150 amps of current, beefing up your battery isn’t a bad idea either. If this sounds like your cup of tea, drop into your local authorized AudioControl dealer and check out the new LC-1.1500 amplifier.

Sony has been steadily increasing its share of the head unit market with the introduction of feature-packed solutions that continue to give consumers the connectivity and source options they want. The latest addition to Sony’s source unit offerings is the XAV-AX5000, a 6.95-inch multimedia receiver with Apple CarPlay, Android Auto and Bluetooth. The 
Sony calls the display on the AX5000 bezel-less. The trim panel around the display is only a few millimeters thick and gives the unit a very clean and tidy look once installed. The display has a resolution of 800 by 480 pixels and uses a capacitive touch panel. Unlike resistive touch panels that have a plastic texture, a capacitive display is the same as what we are used to on our smartphones — crystal-clear images with a very responsive touchscreen interface.
As mentioned, the XAV-AX5000 includes Android Auto and Apple CarPlay smartphone integration software. If you haven’t experienced these interfaces, they make it very easy to make phone calls, listen to and send replies to text messages, choose the music you want or get navigation directions to almost any address in North America. The interface uses Siri or Google Assistant voice recognition software to perform the majority of functions, so you can keep your eyes on the road and your hands on the wheel.
The XAV-AX5000 includes two USB ports on the rear of the chassis. USB 1 is compatible with iPhone and Android smartphone devices for CarPlay and Android Auto. USB 2 takes care of connecting a USB memory stick to to play MP3, WMA and FLAC digital media files. USB 1 supports WAV, ACC, MPEG-4, WMV, MKV and Xvid files as well. Audio files can have a maximum sampling frequency of 96kHz and video files can have a maximum resolution of 1280×720 pixels.
The XAV-AX5000 includes a dedicated backup camera input with trigger wire to allow you to see objects or people behind your vehicle when parking or maneuvering. The system also includes an external Bluetooth microphone for excellent voice recognition and Bluetooth call quality. Finally, the system is compatible with the majority of factory-installed steering wheel mounted audio controls using a third-party interface, or by using the Custom Steering Wheel Control set-up on the radio itself.
Sony introduced their new 
The woofers from the set are based on a stamped steel basket. Mounting holes and tabs are provided for 6.5 and 6.75-inch bolt circles. The cones of the woofers are made from Sony’s proprietary MRC (Mica Reinforced Cellular) polypropylene. In this application they are reinforced with aramid fibers. The result is a low-mass design with rigidity more than ten times higher than competitor polypropylene cones, but just a fraction of the mass. Rubber surrounds and poly dust caps round out the moving component features. Sony includes trim rings and a set of grilles with the woofers.
The midrange drivers in the XS-GS1631C set also feature stamped steel baskets. Two mounting tabs are provided and serve as a direct fit for Toyota, Chrysler, Dodge, Ram as well as many GM and Ford vehicles without the need for modification. In some cases, the midrange drivers use the factory mounting bolts. Each midrange speaker uses a compact neodymium magnet that helps keep the overall mounting depth to a diminutive 1-7/16 inches.
The tweeters in the set include provisions for flush, surface and angled installations. Unlike the midrange, the tweeter design includes a grille that is optimized for installations where the unit will be visible. The tweeter has a 1-inch synthetic fiber design for smooth and detailed sound.
For a truly amazing listening experience, combine the XS-GS1631C with Sony’s new six-channel 
Did you know that about 25% of accidents take place while a vehicle is in reverse? To reduce the chances of injury or accidents, Firstech — maker of Momento in-car camera solutions — has recently introduced a complete backup safety solution. The heart of this solution is the 
The R1 is a 10.5 by 3.2-inch mirror designed to equal the quality, performance and reliability of a factory-installed mirror. During normal use, the mirror works just like the mirror that came with your car or truck. When the mirror detects a video signal from a camera, a 4.3-inch 480 x 272 pixel screen on the left side of the mirror displays the image. The screen is visible through the reflective coating, allowing you to see the camera image clearly, even in bright sunlight. The R1 includes a built-in light sensor that adjusts the display brightness to compensate for day and night operation.
Finally, the 
Sony introduced its new six-channel 
Most factory-installed source units only provide 18 to 20 watts of power. The XM-GS6DSP will serve up 45 watts of power from its four main channels to give your music an extra kick. This power level is the perfect complement to factory-installed speakers or an upgrade like the 
The XM-GS6DSP includes dedicated six-channel preamp and speaker level input connections on Molex plugs. The preamp input will accept up to 6V of signal and the speaker-level inputs will take as much as 12 volts. The tweeter/front channels include an optional high-pass filter that is adjustable from 500Hz to 4kHz. The mid/rear channels include a 50 to 500 Hz high-pass filter and a 500 to 4kHz low-pass filter. A three-position switch allows for full range, high-pass or high- plus low-pass operation. Finally, the woofer/subwoofer channels include an optional 50 to 500Hz low-pass filter and an adjustable bass-boost circuit that adds up to 10dB of boost. The woofer/subwoofer channel is rated to play from 20Hz to 10kHz.
The onboard DSP processor is accessible by a Bluetooth connection from your smartphone using the 
The Sony XM-GS6DSP measures a mere 11.6 by 7.85 inches and is 2 inches thick, which is perfect for installation under a seat or behind a panel in the trunk. All of the connections and controls are along a single side of the amp, making it easy to install and configure. The power terminals will accept 4 AWG spade connections, and the subwoofer channels can handle 12 AWG spades without any problem.
As mentioned, the XM-GS6DSP is an ideal amplifier for most OEM upgrade solutions. You can power a set of front and rear speakers from the main channels, then add a subwoofer to enhance low-frequency output. Alternatively, in a three-way configuration, the flexible crossovers afford you the choice of a two-way front stage using a set of woofers and tweeters, or you can build a three-way stage using passive filters between the midrange drivers and the tweeters. The latter is a nice upgrade that provides excellent musical clarity and stage height in your vehicle. If you don’t want a subwoofer, but still have room for a 3-way front stage, the extended frequency range capabilities of the woofer/subwoofer channels can be used to power six speakers in a fully active configuration. Adding a second amp, rear speakers and a subwoofer would make for a stunning listening experience.
