Chevrolet, GM & Holden Audio Interface for Vehicles with MOST-50 BOSE Audio

The M650-GM produces a completely flat audio output without any factory time delay or equalization, eliminating the need for summing devices, an audio correction DSP or the removal of the factory audio compensation microphones.

It is 100% plug-and-play, installing at the factory tuner in of GM vehicles fitted with the BOSE Audio System. Installation of the interface requires absolutely no modification to the vehicle or the removal of any factory equipment and can be used when completely replacing the factory speakers, or in any combination utilizing the factory audio components. Volume, Fade and Balance are supported through the factory radio and steering wheel controls.

Utilizing a 128 bit per channel floating point DSP and 192 kHz 32 bit DAC, the M650-GM produces a 6 channel analog output (Front L/R, Rear L/R, Sub and Center) with a peak voltage of 6.3V and a S/N Ratio of 112dB. All warning chimes and audible turn signal indications are attenuated to factory levels and, along with Onstar®, Navigation prompts and Bluetooth, are passed to the proper output channels, eliminating the need for an external speaker. The unit provides a 500mA output for controlling aftermarket devices and, additionally, retains the factory 3 band equalizer (high, mid and bass).

For use with 3rd party digital sound processors, the M650-GM includes a variable TosLink (optical) and S/PDIF (coaxial) digital output which may be used simultaneously with the analog outputs, or by themselves. The variable digital output allows for the system volume to be controlled via the factory radio and steering wheel controls without the need to access any 3rd party controller.
