My son wasn't happy with his factory Bose system so he has begun to build a new system.
The local 'Boomer Mcloud's' sold him a VW wiring harness and told him that the 20 pin connector on his system was just for the CD changer- and that this harness would work. So he dilligently soldered all the wires to his new deck, plugged things in and had a deck that lit up, appeared to work, but put out no sound.
The car would start at this point.
There were a bunch of speaker ground wires from the new deck that were not connected to anything- and he grounded them to the chassis to see if that would give him sound. It didn't -- but the car quit starting. It turns over fine, but doesn't fire. It's in the driveway & it's been raining for days so I haven't even popped to hood to see if it has fire or gas.
Shortly after we saw the pinout diagrams on the old deck that showed the speakers on the 20 pin plug-- went to Circuit City- got hooked up & now he has a stereo-- but he can only listen to it in the driveway.
Any thoughts on what we might have screwed up during the install of the stereo? It seems like an unlikely co-incidence that something else failed as we were working on it. [Though it was started and turned off several times in succession as he tried different things to try to get sound from his speakers.]
Thanks, Jim Son's Car;
