Audio info: VW Mk4 GTI OEM Monsoon Amp Sony headunit Polk audio speakers and tweeters I'm having an issue with my front driverside speakers. When the "left front negative" wire is unplugged from the headunit harness my speaker will play music but constantly buzz and pop. When I plug in the wire my headunit goes into failure mode. Speakers and tweeters are brand new and I had this issue before the install. My guess is that the wiring is bad. I bypassed the harness to check if the harness wiring was bad. Didn't fix anything. So the wiring between the speaker and harness is bad? I don't know where to go from here. Any help would be much appreciated.
