07 Tahoe LT w/Bose adding an amp with PAC-GM1416

MattyZ · Feb 28, 2012

So I am wanting to keep my factory HU and Bose amp for my OnStar and front 6"sub, but want to add a 4 channel amp and replace my factory speakers. I have the PAC-GM1416 and my center console torn apart and ready to hook it up. Where is the connection to the amp that I need to tap into? Or do I come off the back of the HU with the C cable?

I havent tried this harness yet, your my guinepig since I want to do the same thing with our 07 denali but when I had an 04 Sierra HD it plugged into the back of the headunit.

So I have the details on taking the bezel off, the stereo out and hooking up the PAC unit. Want details or pictures before I do it? I should have it done today.

I would just ditch the factory sub, I would think that once you get a new amp and decent speakers they will over power the factory sub anyways.

I already have an amp pushing 2 12" Rockford Fosgates, I am adding a 4 channel amp and replacing my front and rear speakers. I have the PAC unit in and everything still works fine. I will post some pictures here in a bit.

Ah yes then I wouldn't worry about the front sub working.

The entire process took about an hour, but that's me taking my time and checking everything still works before I put it all together. The back of the unit has 2 plugs that look a little different so there wasn't any issues on which A, B, or C cables to use like the instructions show. The RCA cables are in easy reach and I am just waiting on my front components to get here. The PAC unit was about $35 from Amazon.

I wonder if that pac unit will work on mine. I have bose with the nav and have been receiving conflicting reports about it working with the so called premium system. I am not sure if mine is considered premium or not. Looks like a easy install though.

Just figured this out today after calling PAC audio. pac1416 works with all bose systems except those with the Y91 premium code. There is a sticker in the glovebox that has the codes...If no Y91 then it will work.
