[QUOTE="highhpsupra, post: 1915692, member: 569075"] I hooked up a new amp recently and when i was setting my gains using the tutorial i was getting 0 voltage on the speaker terminal regardless of how high/low my gain was set. The amp powers up fine and shows 14 volts when the car is running. I also tried to check what voltage was coming through the RCA's and it showed 0 volts as well. (The RCAs were connected to the rear preout and i was using a DMM on the other end of the RCA cable). I dont know if this is a good way to check because Im not sure if the deck (pioneer 4600MP) sends a voltage to the pre-outs regardless of whether or not its connected to an amp. PS. the amp is gonna be benched to see if its an amp problem or something else. any help will be appreciated, if i missed any info, just ask. thanks in advance! [/QUOTE]
