Bose CD player question.
I have a 94 C4 with the regular tape player (non-bose). I just purchased a Cd/tape player that is Bose. What do I have to do to make this CD player work? Do I need the amp and speakers, just the speakers, is there a way to rig it up to make it work without buying all this stuff, or did I just waste my money? Please help me.

Bogus could answer this better but I think you are gonna spend a lot of time and money making that work when you could install an aftermarket system that looks and sounds better for less money.

NO!! This should work.
Plug that head unit in.
Here is why I think this is the case - the head unit, on both the bose and the delco is a dummy. The receiver module is the different part!!!
I have been over the Helm Manual on this quite a few times to confirm my idea, and I am convinced it will work.
Do it.

Here we're looking at what goes into that box. Presumably we've got a line-level signal on both systems here. The other connections are powers, grounds, and a data line.

Exactly.
On the earlier units, the head unit was it. In 1990, when they redid the dash, they totally changed the audio system. It used different speaker locations in the front, new amps, new speakers, new head and, most unique, the receiver module.
If you check the schematics in the Helm Manual, you will find that the head unit to reciever circuitry is the same between the bose and the delco systems. The difference occurs on the outbound side of the reciever.

I will be curious to see how this test works out.

I don't know about the head unit, but when I went to get a (Bose) speaker replaced with a different speaker, I was told that the Bose speakers are 2 ohms impedance, while most others are 16 ohm impedance. There are also speaker units with 4 and 8 ohm impedance. He said that, while the speakers will probably work, they won't give optimum sound due to the impedance mismatch. He said that many people replace the Bose speakers with "better" speakers and get unhappy because they sound awful. They then trash the Bose unit and go with aftermarket. Just something that I was told at the sound guru place (TNT Audio).

Thanks BOGUS. OK - I may be confused a little. Head to control can be changed out - no problem. But (and this is where I may be confused) the OR in the diagram indicates that I can take out the amps and drive a 6 ohm speaker directly from the control unit. ???

Ok, the verdict is in....Bogus, you are the man. I hooked it up and it works perfect with no sound deterioration or any differences. Sounds exactly the same, and functions the same. So a Bose head unit can be switched into a non-Bose car. I totally agree with your theory. Thanks for all the help guys.
