Re: Urgent stereo help needed
In my '88 90 Quattro, the rear speakers are powered - however, you
can easily bypass that in a couple of ways:
1. Find the line in pins on the connector - I don't have the diagram
around, as I threw it away (shame), but it should be pretty obvious
from looking at the circuit board. The other pins are power and
ground, maybe a sense pin to turn on the amp. Regardless of the
dealer's claim, it's no different from an ordinary line input -
you just have to find the appropriate connector.
2. Bypass the amplifier totally. This is what I did. My car has
separate woofer/midrange and tweeter, so initially I was worried
about building a crossover, but I discovered that the built-in amp
doesn't use an electronic crossover anyway - it's mechanical, with
the midrange rolling off at some frequency. I desoldered the
speakers' connections to the amp and jumped them directly to the
connector, which is hooked to the radio. The tweeters are wired
in parallel. (The built-in amp looked not very sophisticated anyway.)
3. Install better speakers. This is what I would have like to do,
except that the dimensions didn't allow for anything bigger without
some rear shelf surgery.
Setup #2 works fine for my non-golden ears. The receiver is a Sony
XR-something with about 4 watts per channel.
