C2A-GM24

The C2A-GM24 allows you to add a 2 channel aftermarket amplifier for GM vehicles with Class II data bus. What makes the C2A-GM24 unique is that is takes the fixed level audio signal from the factory head unit before it gets to the Bose amplifier and gives you a variable output. The C2A-GM24 outputs are digitally controlled by the headunit's volume knob. You get full range audio signal, not a Bose specific equalized output, highpassed or lowpassed output. 2 channel RCA outputs with left and right level adjustments for matching aftermarket amplifier/speaker audio signal to factory speakers.
