I am having trouble with the correct wiring for a Kenwood Receiver (KR-9508), amplifier (KA-94), cassette deck (KX-71RB), CD player, and a Fisher graphic equalizer. Each piece is from the early 90's era, so I haven't been able to find a helpful website on setup or the correct manuals. If someone could suggest some sites on how-tos, that would be great. And, please do not recommend Kenwood, because I've tried with no success. Thanks
