Someone please help with audio!
Just installed a car pc in my 2003 tib gt. i have the infinity sound system. I have an external sound card that has 3 sound outputs for front, rear and sub. I have the adapters to run from the card's stereo output to rca to speaker wire all hooked up and the sound works, i checked it with other speakers. My problem is i followed the wiring diagram from behind the stock stereo. The only way i get sound to all my car speakers is to run ONLY the positive speaker wires to the corresponding wire in the harness. I always thought you needed both pos and neg but when I hook up the neg wires it cuts out the sound immediately. Also, while I have the pos wires hooked up i get extra noise in my speakers. If someone can help me hook this up I will pay you. I would rather pay someone on here that may have experience rather than in my hometown audio store possibly not knowing what they are doing because it is a small shop. If no one can help me than can someone please let me know of a place around the chicago area that will definitely do the job without any problems. I'm tearing my hair out, I've had the pc half assed installed for about 4 months now and finally finished molding my screen into my center fascia. Looks awesome by the way. I'll post pics when I'm completely done. Any help would be greatly appreciated.
Here is a little more detail-- The card has 3 outputs. One for front speakers,one for rears and one for subwoofer. They are all stereo out puts that have been converted to bare speaker wire at the ends. So at the end of each output there is bare speaker wire for left and right speakers. This is what I am hooking up to my stock stereo harness. I have the stock infinity amp but there are no rca's or anything, just the wiring harness that goes into that also.
