86 radio wiring

[SEdgell]

When I got my car (86 325es) the factory wiring harness for the radio was cut, does anyone know the color codes for the factory speakers?

premium sound or regular?

[SEdgell]

I'm not really sure, I know that it has the dome tweeters next to the mirrors, and then the front and rear speakers.

Sounds like Premium: http://www.verrill.com/car/e30_stere...gdiagram.shtml

Great, thanks...

None of this looks like my wiring, do you have one for the other stereo?

Thats because its for a late model e30. Yours probably has the fader in the dash correct?

Just Goooooooooooooogle it

Yeah, the es is gonna have a fader in the dash.

Here is the deal: you have 2 speaker wires coming out of your deck, plus 1 ground for both L+R. Normal power, switched power, dash lights, ground and power antenna/amp turn on.

The 2 speaker wires and the ground go to the fader, which makes the 2 into 4, and splits up the grounds, but only left and right, not 4 separate grounds. These 2 grounds are still actually the same ground, but no matter, because all 4 go into the amp, which runs the speakers.

So the real question is what are you trying to do?

[SEdgell]

Yeah, it has the fader. What I'm trying to do is just wire an aftermarket head unit in the car so I have some sound. The previous owner took the old one out and cut the harness. So I'm just trying to find which wire goes to which speaker.

[StereoInstaller1]

The wires in the dash do not go to the speakers.

Any wires in there that look aftermarket?

[SEdgell]

Nah, they look to be factory. There are a bunch of cut wires, and the wires from the fader have been cut also. I may just go a head and rewire it myself...seems to be the best way to do it.

[Mless5]

Just throw new speaker wire to all 4 corners and connect them to you HU. Color code should be the same as in the link I posted for 12v, switched power, ground and antenna.

X2 bubba.

Early car means all new wire.

You might want to catch the rears under the rear seat.
