Re: 2008 Sierra, No Bose!!!
Alright thanks, I tried to do it myself lastnight, I know for sure the power wire is correct, there is no 12volt ignition power in that harness, so I just put a togle switch from the 12volt lighter wire to the amp on wire, seams to be working ok, but would rather it turn on and off with the car( incase i forget it). Now I think I have the 2 front speakers wires figured out, now there is one speaker negative i'm not sure of....Can I just hook it up to the other speaker negative? will this work? I didnt hook it up yesterday and I had some sound coming from the sub,, but i dunno if I only had partial power to my amp inputs sence only one negative was hooked up..
