new deck = no sound

[King Luis]

got my new deck in and everything works except i get no sound.
the previous owner had a sony deck in there had did a hack job.
i have everything wired up and the deck works perfectly fine but no sound.

now i'm not going to rewire the whole car so don't say rewire it.
could it be this common ground issue??? where would i ground the deck to instead?

the deck is a new alpine 9856 with premium sound.

has anyone got an idea???

try reconfiguring the remote on, I had to do that to get the CD player to work in my e34...

just figured it out...it was the remote on for the amp....it was wierd, it was a violet to white wire that had to go together.
thanks for the help though.

for the record. i found this only today off of bimmer forums that could be of some help to lots.

The official e30 Aftermarket Radio Install Write up!
If you have the premium system ( tweeter on doors, plate speakers on rear deck )

* Yellow wire from new head 12v+ goes to Red/grn in dash
* Red wire from head ign goes to purple/wht in dash
* Black wire goes to brown wire in dash plus two extra brn/blks that were attached to old head. There will be three wires total hooked to the black from new head.
* Blue/wht from new head goes to both white wires in dash. If you don't have a blue/wht on new head, use the blue.
* That will leave three wires:
* If your new head has a dimmer lead ( usually orange ) it will attach to the red/grn lead in dash. If the new head does not, TAPE THIS OFF. No sense blowing fuses now when you are so close to sound.
* White wire from new head goes to yellow wire in dash
* Grey wire on new head goes to blue wire in dash.
* Tape off ALL REMAINING WIRES FROM NEW HEAD, don't allow them to touch each other or any metal in the dash.
* This uses the factory fader, and factory amp, without messy rewiring.
* Anyone who tells you that the new radio has more watts than the old amp needs to look at what it takes to make 40x4 rms. It sure ain't gonna fit inside a deck, and it will need at least 10ga power wire, which new radios don't have.
* I worked the install bay many many years. I did every e30 like this, and my 88 535is has had this wiring for 6 years, no problems. There is a common thread on these boards that says 'rewire' when it is not needed.
* If you have the std system without an amp, it is just as easy, there are two extra wires. Email me for details if so.
* If you are confused, take it to a reputable shop ( no Best or Circuit in the name ). 40 bucks and you will be in and out in 10-15 minutes.

its 12am here and I'm tired and bored. The proper illumination wire found in the dash of e30's is Red/GREY not Red/grn as I said. So shoot me, lol.

Whether or not rewiring is necessary is completely subjective, but to say the factory fader isn't a piece of shit would be lying.

Hey

Well that thing that you got from the other forum sounds right, but I have a 1986 325 es. It is in the E30 series, well at least I think, but some of those wires don't match; like when it says to hook the extra brown and black to the ground wire. I don't have extra browns and blacks. And then it says to hook 12 V to red/green in dash, I dont have red/green in dash. So I am really confused. I am not saying that is wrong what you posted, I am just confused how this can help me or where I can find the wiring for my car.

Thanks,

JV

the extra brown/black wires are the ground wires for the speakers.
as for the red green. it was kind of hard to find, i thought it was red and grey at first.
