I have read alot of topics on the LOC adapter to change speaker wires from the stock HU into rca's. But would I need it if I used a good quality amp. I am considering the Infinity 7541 4 channel amp. Infinity states that I could hook up the 8 speaker wires from my stock HU to the amp and then out to my 4 speakers, but I am a little leary of introducing noise. I really really want to keep the stock HU. Am I being misled, will I get it all hooked up with high expectations only to find out it doesn't sound good, or will it sound great?
