Dont think Im a moron, but I am curious how to hook up a amp and subs to my factory deck in my 90 legend. I just bought a 1200 watt Kenwood mono amp for my JL audio 10w0 10 inch subs. I had a friend with a 90 boniville who had subs and an amp hooked up to the factory deck in his car last year, He used a portable Cd player with the tape deck adapter for a CD player. how would he do that if it had no RCA pre outs? Could a car of that year have RCA pre outs? The only reason I am askinf this is becuause my JVC cd player is being fixed, And I am in need of some bass! Can this be done in a 90 legend?
