Looking to do the same thing on my 19 High Country. I was looking at PAC Audio and think they have a GM harness that might be plug and play with a little modification to use the existing factory speaker wires. Anyone have experience with these harnesses?
Yes, I have one of there T-harnesses from my previous 15 Yukon and it works good for adding a sub. Currently I have a 19 HC and really want to “Un Bose” and get a good clean flat signal. I have not figured out how to turn off the “speed regulated volume” on this one. Always seems counterintuitive for the volume to go up with speed and then the bass rolls off with that, really annoying.
So I have checked with PAC Audio and they don’t have an Amp Pro for these yet. I got 2 different answers., 1 nothing in the works and 2 should be 1st half of this year.
So are there any differences in the Zen Audio and the Amp Pro?
