Sorting out the speaker situation Just got my 96 318ti a couple weeks ago and I'm slowly working through my ticket list of items, I'm finally tackling the audio and I'm running into a brick wall. All the sound coming out is clearly just pre-amp from the radio. Here are the facts as I know it: 1. There was at some point an aftermarket head unit on the car, the BMW harness has been cut out and re-spliced back on. 2. Whoever re-wired the harness and stock radio back in did not wire two wires, one a thin black wire, the other a thin yellow wire. 3. Rewiring those two did not help the situation 4. I found that the speakers in the back (the 4") were gone, so I replaced those with some clarions and a bit of ghetto rigging. Even after that sound is awful and after poking around I discover the factory amp, which is clearly not functioning at the moment. So.. Does anyone know if A. There is a fuse for this thing (the guide in the fusebox says there is a 20amp fuse somewhere in the trunk) and B. If there is a way to diagnose whether it is working or not? Is it possible that whoever put in the head unit fried the amp? Anyone know where I can get a wiring diagram for this monstrosity? Thanks, Brian Horton |
