Hi there, I have a 95 Range Rover 'Classic' with the factory Harmon/Kardon upgrade. The system has 6 speakers plus a factory amp, subwoofer and external CD changer.
I replaced the factory AM/FM/tape head unit with a Parrott RKi8400. I had to splice the wiring because I couldn't find a harness adapter. I did this very carefully since I know it's a bad idea. After I did that, NO sound whatsoever came out of the speakers.
I then took it to my local Al & Eds shop and he gave me a R+L (what looks like) RCA cable to plug into the (yet unused) RCA R+L jacks on the back of the head unit. Now I get sound but it won't fade front to back, and there is a lot of ground/RPM feedback, and a loud pop when the stereo starts up and shuts down.
Any help on how to remedy this would be very much appreciated!
