Radio Wiring

[shay91]

I have a 89' 325i Convert.
Can anybody tell me the wire configuration?

Purple/White..... 12+ constant
Brown/Black...... Ground
White............... Power Antenna
Red/Green......... ???? (Makes the chime come on)
Blue................. ????
Yellow.............. ????
White............... + Front Speakers

No black wires or nothing with a black stripe to tell me the negative for the speakers. I've touch the wires to something and the system played but I couldn't figure it back out. The old connectors have been cut.

blue is power antenna
the two whites are for one of the speakers

[shay91]

my white is a power antenna. I put it to the constant and it rose up. I had it once before but when I took the radio out I forgot to label my wires :(

[shay91]

Can that guy StereoInstaller1 chime in here lol

White is the color on the car for the antenna. Blue is the color out of an aftermarket head unit. I just did this yesterday but can't remember the other colors. I did a search on the forum though and found them pretty easy.

So now you need to figure out if you wanna bypass the amp or not.

Is the factory amp worth bypassing? I got a Alpine CDA150 for a e34. Just curious which way i should go.

I wired the entire car fresh for my new stereo. 16ga wires for the speakers and for the power of which I only used what appeared purple to me as the 12 volt switched power... took the ground and power from the cig lighter. (course the left over bits of the harness was mangeled from a PO)

Their's too many whites mention, How do you figure out all of them?? How about some links for an accurate set up?
