I have a 1995 e34, I have the premium sound system with that crappy 45dB Signal-to-noise ratio and 25watts to each speaker BMW amplifier.

I have an amp here i'd like to wire to my 4 new pioneer speakers. So far i've found my remote power wire (white) and have the amp powered up. Here is my problem

I need a pinout for the two wiring harnesses for that thing. At least telling me what color wires go to what speakers, and what color wires go to what which speaker, and what color wires are my inputs for said speakers.

I'd like to avoid having to rewire my car for 4 speakers, Replacing the stock wiring seems like more trouble than its worth.

Ok, seeing that diagram its pretty clear i need to figure out how I want to do this. I was kind of hoping to keep the stock amplifier in the car and still have use of all 10 speakers, but that isnt going to happen the way the amplifier is set up.

What i've done so far is replace the front kickpanel speakers, and the rear midrange speakers with a couple of pioneer 2-way speakers.

I'm looking for some better sound quality on those speakers, especially on the bassline, which is causing all kinds of distortion and cloudy sound, which I believe to be caused by running 40w speakers on a 25w amp.

I'm considering bringing the leads out of the back of my head unit to my trunk via an rca cable I have, unless there is a way to keep the tweeters and whatnot providing sound.

The amplifier I have, when I attempted to hook up one of my RCA connectors, seems to have a little problem with powering anything. The head unit flickers along with the power switch on the amp, neither really turning off, and the head unit appears to play, but there is no sound whatsoever when I tap the wires for the stock amp and send them to the aftermarket amp. I think this might be either improper wiring, or possibly not enough power.

Any input or output from my speakers will be appreciated.

Ok, well so far i've succeeded in fucking up my BMW amp. I think its a fuse or something but i dont have the little screwdriver to open the thing up, stupid torx thing.

Anyway, I'm thinking about just buying the pioneer amp i want, and rewiring my speakers to work with it, should make life alot easier as I'll be able to just use some interconnect cables to hook it to the head unit and I can toss the stock amp in the pile of boxes I have containing various parts that have been removed through the ages.

That wiring harness is the DEVIL i tell you, the DEVIL. And for some reason the sound system wont work without it connected, even bypassing the amplifier entirley fails to work. Ah well, chalk up another cool set of parts I need...
