This is for anyone else interested in radio replacement in the older cars
with dash fader, as much as it is for Shri.
The BMW HiFi system used some funky speaker wiring. The easiest and most
common way to install an aftermarket 4 speaker radio without an amp is to
run new front speaker wires from the radio to the speakers, and then use
the wires from the original radio for the rear speakers, placing the
factory fader on full rear.
The left speaker wires are always yellow, right is always blue.
Also, a hint to determine speakers by wires is to jump a 1.5V battery
across the two wires, the corresponding speaker will crackle.
