Can anyone help me.  I would like to connect my amp and box up to my new Trailblazer.  I have a line-to-level convertor and require the following:

1.  Location of the remote line to turn the amp and crossover on.

2. Location of the powered Left and Right channels (outputs of the audio amplifier).  Front or Rear, doesn't matter.  Physical location of audio amplifier?

If anyone can help, it would be much appreciated.  Email me at aguerra@rogers.com

Thanks.

1. You must use a switched ignition power wire for the remote turn on lead. The new HU from Chevy do not have a switched ignition source as they are OBDII systems. Use the PINK wire in the ignition switch harness.

2. Have not worked on this model for audio yet.

Thanks man, I will give it a shot, by the way, it looks like the 2003 speaker outs are the same as the 2002.  I found the colour coding for the speaker outs on this forum at https://www.the12volt.com/installbay/forum_posts.asp?tid=4933&KW=trailblazer

Thanks again.
