<trying this again in the 100/A6 forum - no responses in the audio forum. >

Hello everyone,
I just got a 1994 100S Avant, with a stock gamma radio - it doesnt have CD Changer controls on it. it doesnt say BOSE either, just gamma.

Since I don't know the code for it yet, i installed my VW radio in there - same plugs. Well, there is no sound in the rear speakers at all.

Question: Which speakers are "Active" - why are the rears not sounding and how would I hook up an aftermarket stereo? Would I need to send the pre-amps to the rear speakers (or to all the speakers?)

Did anyone do this without re-wiring and without changing the stock speakers..

Also, what is the difference between Bose and Gamma radios other than the CD-changer controls that are missing from the gamma? My gamma says Blaupunkt, btw. (I had idea about that before)

Someone please help out. thank you.

Will a DELTA radio from 1996 A4 fit and work OK?

I, too, have a 94 100S wagon. I was having speaker problems a few years ago and looked into replacing w/aftermarket. Bottom line is that it would have been a total pain. I ended up getting a refurbished head unit from dealer for about $100. It worked fine for about 3 years and is now bad again.

My understanding is that it is only the rear speakers that have built-in amplifiers.

Good luck!
