A few weeks ago, I searched for and found some images of a factory amp and the connected wires. I thought Rob Edwards had supplied a couple of those pictures, but I cannot now find any of those pictures.

On my 89, I am reinstalling a factory amp. The PO cut the wires and the connectors. I sourced some connectors from Tom down in Austin and reinstalled those, but IIRC from the pictures not all the connections on the amp have wires connected.

Anybody have pictures of the wiring on a factory S4 amp?

Really?? No one has a picture of the factory amp wiring in situ?

Blau BQA 80 amplifier. Hope this helps.

found the DIN pin outs if that helps also. This was from a BQA 120, but I think DIN pin out the same.

For '89, I assume you're going back to the 6 channel amp for the 10 speaker system? Here's the description and wiring schematic from the '89 service info book.

And pics of the amp connections.

Thank you Bob and Rob.

I think that I can now figure it with these images.

Rob, any chance the pictures illustrations from this post can be put back in?
Thanks!

Can you explain why the DIN IO does not match in the posted picture?


Thanks,

Rob Edwards

I don't remember all the photos, but here are a couple of views:

Thanks Rob, good pictures. The one that shows the DIN at the amp appears to reveal there is no pin in the 2 locations nearest the key notch (1 to the left, 1 to the right). At the moment I can't see the amp, I have not committed to removing the seat yet. I was trying to drive the amp temporarily from the front console with an alternate head unit in an attempt to determine if my issue is the head or the amp so that if it came back to life with the alternate head I would know the amp is OK and not have to pull the seat.

My system is in the 1994 968 apparently having the 10 speaker system. So I don't even know for sure the equipment is the same. You post and mine plus other are just pieces of the puzzle I guess. This reverse engineering is tedious!

Is your head unit the CD-2? If it is then the odds the DIN connection is the same is much better, I guess!
