My radio in my 2007 Chevy HHR will only output sound through the tweeters on the columns by the windshield. I tried replacing the radio and still had the same problem. I was then told to replace the amplifier. I checked your wiring diagram and your schematic on this website and was told it was in the rear quarter panel. We had to remove most of the interior panel to get to it and there was not an amp in that location. Would they locate it elsewhere?? My 2007 Chevy HHR is the LS model, just a basic single cd radio without the satellite radio. Please respond with another location or maybe a fix for this problem. anyone know? Thanks, Mike Kerby.
I have a 12″ subwoofer and a 350 watt amp to hook up. I want to keep my factory radio so I bought a converter that hooks into the stock speaker wires. I hope this diagram is correct. Thanks foxxx.
