No, I was going to unplug the speaker wire harness at the amp, follow the colors, splice new wire in and run them to the hu. I'm not using an amp at this time. Will try the home run approach just thought it would be easier since all the wires are in one place. Will my PAC RP5GM11 still retain everything with home runs?
I'd contact PAC to be sure, but my presumption is no. I believe the output from the blue module is designed to send the appropriate signals to the BOSE amp - which you are intending to bypass.
You may end up leaving out over half the PAC kit or you may need to get creative with wire routing. I don't know how they would "inject" notifications (OnStar, Chimes, reverse radar, etc...) into the audio output if the output isn't going to be processed and amplified by the BOSE amp. You probably need a different kit or an optional harness.
Also, "wire color in" does not always equal "wire color out" when it comes to amplified systems. Quite often, they aren't even close.
If I started with a BOSE equipped vehicle and the amp was out or I wanted to remove it, I'd home run everything and give up OnStar, door chimes, etc... I'm not big on steering wheel controls for audio, but they're are solutions to retain just SWC and wire everything else direct. If you're putting in a NAV system - most manufacturers have solutions to get most of the inputs you need, simply. Park & reverse can be spliced into. I'm not sure about the VSS as I've not had to deal with that, yet, and a lot of them don't even need the VSS as it can get at the very least "good" data from GPS.
Let us know what PAC says - someone else might find the info useful. I also don't mind finding out I'm wrong.
