Upgrade Tahoe to Bose amp?

I have a 2002 Tahoe w/factory stereo (126 watt amp into 9 speakers) in deparate need of more power.   I see that the 2003 Tahoe comes with a Bose system, as did earlier Denalis and Escalades.

Can I replace my OEM amp with a Bose amp? Are the input and output wiring harnesses and plugs the same (or does someone make adapters?)  I'd love to find a plug and play solution instead of chopping up my truck.

Hi Tim,

I don't  know if anyone makes input/output harnesses for your system.

I just upgraded my system in the same vehicle by installing an audio contol EQS(preamp eq/xover with line driver), Rockford  550X 4 ch. amp wired to the factory speakers and a Rockford bd1000 powering a cstom built vented box.

A factory amp is located behind the glove box that uses GM standard color code, I just ran the output going to the factory speakers to the input of the EQS and connected the amp to the factory speakers.

This system really impressed me because I don't know what speakers the factory used but they are capable of handling the power of the bigger amp and  everyone who has heard it ask can't believe that I am still using factory speakers.

Hope this gives you some ideas.

Karl,

I knew you guys at PAC would have the answer.  thanks.

A quick follow up: what if I replace the headunit also?  Are the wiring harnesses/plugs the same, or am I going about this all wrong?  It seems like this would be the easiest and cleanest way to get more power, but I wonder if I'm just setting myself up for more headaches...
