Any one have any info on the 2002 trailblazer wireing for the Bose system. I am trying to tap into the system to run some amps. I want to keep the stock unit. I cant use the outputs of the amp because all the outputs are crossed over and I need a full range output. The output coming from the deck is full range and is a fixed output so I dont have any volume control.

I tested the rear output of the amp. It seems like its still crossed over. I played a 40 hz tone through the system and got hardly anything out of it. as I raised the frequency the out put raised. this system is different than the Denails or esclades. It has decated channels for each speaker. and each channel is crossed over. Front doors are low pass the dash is high pass and the rear doors seem to be from about 80 up.
