First, the car this is going in....
97 A4 1.8T with sport package and premium sound (though I dont think its
bose - no logos anywhere on the casette deck or speakers etc....) I believe
the rear speakers are amplified by some crappy Nokia amps sitting under the
now on with the story...
alrite, after much trouble with a crappy install by professionals at a local
store, I got fed up and returned their POS back to them coz they were never
able to get it working properly.
So, I purchased an Alpine 9807 deck and I am going to install it myself...
I also bought the AUDI wiring harness consisting of 3 connectors - A (8
pin), B(8pin) and C (three rows, 20 pins) to plug directly into the factory
So far, so good. Now the confusing bits... on connector B (which has all
speaker connections), I can see only 4 terminals - FRT RR and FRT LFT +
Now for the Rears, I see on block C1 (pins 1 to 6) pin 1 is line out RR LFT
(pin1) and RR RGT (pin 2) but just one Line out ground (pin 3)
The replacement deck which I purchased has both + and - outputs for all four
I realize that I can't simply add those two -ve leads for the rr
together.... as the new unit outputs a "floating ground" signal...meaning
its not a constant ground
Now, whats the best way to do this? Should I just screw it and unplug the
factory amps and speakers and run new wires just to the speakers?
Howcome the frt speakers are not amplified?
thanks.... I realize that this post will prob result in 10,000 replies about
how I should do more research etc etc and its all been asked and answered
before...anyway I have been trying to find specific info but no luck other
than an audi world article which was a little confusing...all I am saying
is, if you can help, please be my guest...otherwise dont waste your time and
