Line out converter

[Pedro11]

Cool, too bad it isn't an 07+ I have a harness that could be cut and modified to do what I am bout to tell you how to do. I have never done this before so I cannot verify that it will work.
the things you need:
metra 70-2003 gm00-06 aftermarket radio harness (female)
metra 71-2003 gm00-06 factory radio harness (male)
(2) line out converters, three if you want separate sub control

Wire your 71-2003 and 70-2003 together leaving the speaker leads disconnected (I would verify both visually and via multimeter to make sure all wires are in their correct locations and all factory wires have a wire on the aftermarket harnesses). The line output converters will wire to the speaker leads of the 71-2003. The speaker leads on the 70-2003 will be for your leads coming from the amp out to all four speakers.
There is a harness directly behind your a/c controls attached to the back of the subdash. This harness is for bose. Disconnecting this harness and plugging in the 70-2003 will completely bypass the bose system. I believe (not 100%) that bose and non-bose use the same radio, I would verify before proceeding with this venture. Your onstar and auxiliary will be in the smaller harness of the two. I hope this helps and if I wasn't enough help, sorry in advance.

I'm tryin to figure out the same thing but 08 with on star and Bose system

In theory, the same method would work. However, I don't know of a quick and easy Bose bypass on 07+. You could essentially do the same thing using the harnesses under the cup holder if you could find the necessary harnesses.

All good ill have to look in to that. Thanks for the tips.

Any time. Sorry I don't know more about the 07+ trucks. I quit the stereo biz in mid-2008.

I think many people had to quit different industry's about then. Wish we could figure out this damn mess and get back to having fun instead of dealing wi this crapy economy. Still seems like you have a good knowledge base for being out of the game.

Thanks. I didn't quit because I had to really. I quit mostly because I found a more guaranteed paycheck with benefits and less hours. I actually made more take home pay in car stereo but working on other people's crappy cars 6 days a week made me not want to mess with my goat on my one day off. In bigger cities I'm sure the nice vehicle to crappy vehicle would be better, but here in Wichita Falls people wanted to put stuff in some of the dumpiest and nastiest vehicles.

Awesome, thanks for the PNs. I had been trying to do this exact thing for a while now, just could never find a harness side connector to plug into the radio. Seems pretty straight forward and simple to do. As far as the radios being the same, they aren't. I tried my brother's '06 deck(non-bose) in mine and it did not work. All the radio functions worked, but no sound. There may be a wire missing to turn the bose amp on or something. I may get an iPod interface and hack it up so I can have my iPod and keep my system with the stock deck. Now if I could figure out how to add USB input I would be golden!

Any time, I'm always happy to share any and all of my knowledge. I'm as eager to teach as I am to learn.That's good to know about the radios being different, keep that in mind if my method doesn't work on your bose radio, you might end up having to put RCA ends on your speaker leads out from the radio instead of using LOCs.
