In my new Z I am having an issue with my stereo. I did a search to see if anyone else has asked the same questions and I got more lost. Most of the threads were about completely replacing the speakers and HU. When I bought my Z06, I have planned on keeping it as close to original as possible because I do not want to have the same problems that I had with my 97 corvette as far as electrical problems. Well, all the original speakers and HU are still in place, which is nice, but there is an amp and sub in the trunk. It looks like it was a professional install, all the factory speakers work but the sub it didn't work. First thing I did was check the fuses. Under the hood, the power wire was hooked up and the in-line fuse was good as well as the fuses on the amp, so I am getting power to amp. The sub is hooked up properly, as I mentioned a very clean install. So I am at a loss. I have not and really don't want to take the factory HU out see how the amp is wired. I do know from removing the kick panel on the passenger side that the wire I believe is wired into the amp turn on switch is going into the passenger side door. Why would anyone wire into the door with the amp turn on? The only other thing I have not checked yet is the ground. I have not had any luck finding where that wire is grounded yet. Probably the seat post. Any troubleshooting Ideas?

Thanks

 

There is a plug under the passengers kick panel that has a pigtail attached that has a 12v switched wire. Common source for turn ons, relay activation etc.

 

I would post this question in the Audio and Electronic Forum. There are guys there that know about this kind of thing.

 

Thank you I will do that.
