I just bought this used off a guy on CA. He said it worked fine and I beleive him. Anyways I got it a couple days ago and I go to hook it up today and something isnt right. Im not getting hardly anything from the amp. I had to turn the gain all the way up,bass boost all the way up to get my sub barely moving. Now I know my wiring and RCAs,HU are good b/c I just had my JBL amp in there and it was fine. I dont have the bass knob/remote for the AQ amp,do you think thats why its not working right? I had an MB Quart amp that had to have the remote hooked up for it to work right and the Epicenter is the same way. Or do you think something is wrong with the amp itself? I dont know what it could be.
