Radio Wiring and Amp Bypass

[Miasma]

Just got done rewiring my 87 IS. Had a stock amp with premium sound WITH a fader. Sounded like shit, Took a while and had to run new wires for the front lows and highs, But sounds AMAZING now.

I have an 05/87 build date m3, i tried to follow the wiring to see if there were splits for the grounds... no juice... the po had a after market deck hooked up to the oem fader switch for some reason?

i tried to find a wiring manual but am having some issues finding the exact one by color codes of wires that i got... looking to bypass the amp in back and get all speakers grounded normally so no more whining...

even with the whining of the speakers, the luke box sure does wonders!!

Ok I figured I was just reading something wrong.

I did get mine figured out, I just found the grounds for each speaker using process of elimination, that was before looking to see if the proper speaker positives were twisted with a ground.. I dunno if they were, I read that part after I got mine going.
So yeah I bypassed the amp, Im back on this thread because I have a 90 Vert at the shop the guy wants a stereo, and I needed a refresher course on how this is done.


Thanks for all the info

If it has a fader in the dash it will be the "more hassle" version where you use the 4 positives to run the rear speakers and run new wires for the fronts...otherwise, you will have 4 twisted pairs in the dash that run back to the amp, where there are 4 more twisted pairs to connect to.

Just caught this post.

You are confused, and I am talking about 2 different stereo systems.

You are aware you caught 2 completely different installs being discussed, right?

You know you used those quotes completely out of context, right?

Both of those statements, when applied to the proper discussion/installation, are correct.


Either way, did you get your mess figured out?
