FD stereo center amp

BigIslandSevens · 03-26-2008, 08:26 PM

Hello all,
I am trying to figure out why the center speaker doesn't work. I notice that i have 2 wires in the fsm diagram that go from the head unit to the center amp... A Grey wire and a light green/black.. Can anyone tell me if they are supposed to carry power? are thet signal wires for something? I can't tell from the wiring diagram.

Or, do you loose the center speaker when someone hardwires in a sony harness? I have 2 unused wires still on the sony harness still. i have to check to see if they carry power or not.

Anyways , just looking to see if anyone else had run into this with aftermarket head units.

thanks, Dave

No Non bose R2 with a sony MD originaly now a cd explode(cheapo)

Here is the type 1 diagram

Thanks for looking

And the grey wire on the radio end... i can not even find. I'll cut the harness wrap back somemore too see if is down there i guess. There are also a red/black, and a red/green that i do not see on the diagram,other than the connector pin breakdown?? Any ideas? not thinking these are related to the center amp.

I don't have any experience with the non bose system, but I know on the bose system you had to either wire it with pre-amp leads, or get the schoche adaptor which only allowed for two channels. Unfortunately that is not what is going on here. I would imagine that the head unit is not turning on the amp. I can't remember the name of the wire but usually there is a blue white wire coming out of aftermarket head units that is an amp controller that needs to plug into the amp feed.
