Hello. I'm having a issue with a stereo plug & play wiring harness I purchased off ebay. The harness I bought only had 4 speaker wire connections. Well come to find out it somewhat works, but I'm only able to get 2 of my 6 speakers working in my 2003 VW Beetle, and it sounds like the front left speaker in the door has only bass coming out of it. The harness is wrong for my beetle. My Beetle has 6 stock speakers, 2 up front in the dash, front door speakers and 2 rear speakers. Anyone know the correct harness I need to make everything work properly. Thanks for any feedback.
