A little background on the issue: I have a 2006 Chevrolet Malibu 2LT and I had my first head unit installed in December 2009. The 2 radio stations (101.1 WRIF and 88.7 CIMX out of Windsor/Detoit) I listened to most came in perfectly. In January of this year I installed a Kenwood DNX6960 navigation system and the stations worked fine, a couple of days later I installed a 1200watt Pioneer amp and 2 12" subwoofers and then it was nothing but static. I tried just about everything and never got them to work while other stations that were closer to me in the Toledo, Ohio area came in just fine. The two stations I wanted to listen to still remained clear in my moms SUV and my dads truck. Today, I installed a Sony XVT-770BT navigation system and before hooking up the amp I tested the stations and they came in just fine. Then I hooked up the amp and put everything back together and they were static again. So I took it all apart and disconnected the amp wire (the blue one, not the RCA cables) and they suddenly worked. The question is, why can't I get these stations with my amp connected? I have sort of ghetto rigged it by bringing the blue amp wire out of the dash and just twisting them together when I want to listen to those stations.
