Hey guy's, I have the non-Bose in my Max, and I just installed a Sony HU. Now I get engine interference, as well as antenna interference(going up), and when I put a CD in and it's searching or changing tracks u can hear the interferance from that as well. I left the stock amp hooked up. Is that the problem and should I just bypass it by splicing the speaker wires in directly?

 

Check ur ground. Better to ask this in the stereo section tho.

 

what he said.........i had the same problem in my camaro after my freind installed a new head unit. turned out to be a bad ground wire. you just have to figure out which one.

 

That's what I was Thinking. Thanks.
