I want to add an amplifier to my factory HU.  There  is  NO onstar,  but it is a  Bose system,  Delco  6 disc in dash HU.   If someone could help me out,  I need the radio color code for a 2004 Chevy Avalanche.  Also,  will a  standard in-line converter work or will I need a special interface to work w/ the bose system.   I don't want to change  anything w/ my factory sound or speakers.   I am  just adding an amp  and  speaker  box in back.   Any  help  is appreciated.

Thanks

Use a good Line output converter (LOC) and connect it after the BOSE amp in the center console on the subwoofer outputs.

I use the PAC C2A-GM24  for customer's that want to add a 2 channel amplifier to their existing Bose system. Here is the product description:

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.
• User selectable to fade out when adjusting factory radio to front or to rear. Or select to be non-fading output.
• +12volt remote turn-on output.
• Plug & Play, no hard wiring required.
 
Vehicle application: 2003-2004 Escalade (all), Trail Blazer LT, Trail Blazer LTZ, Envoy SLT, Sierra Denali, Yukon Denali, Hummer H2 (2003 only), 2005 Escalade (all), Sierra Denali, Yukon Denali
Note: 2004 Hummer H2 and 2005 Envoy and Trailblazer, this interface will not work! Use the AOEM-GM24 to add a 4 channel amplifier.

Note: The C2A-GM24 does not replace the factory amplifier. If the factory amplifier is removed or disconnected, the C2A-GM24 will not function.
