[QUOTE="Spkrman, post: 1566162, member: 548682"] The noises are because you have the gain up so high... its something you'll just have to deal with. Being able to hear those sounds indicates the amp is probably working fine. 4v doesnt sound right... i'd say something was wrong with your DMM, or you didnt have that setup properly. it coudl be a head unit issue... you can try turning up the sub level on the deck, if it even has a sub level. It sounds like you just cant get enough input voltage to the amp, it happens. New deck may solve some problems, I'd get a new one anyway.. that one you have now isn't up to par... at least get something with a set of sub outputs. [/QUOTE]
