I hooked up the alpine amp mentioned in the title and it turns on blue just fine. But I get no music, so I fiddled with all the controls on the amp just to see if I could get something, going from gain all the way down to just slightly on I get a sort of grumbling noise through the subs(not that uncommon for an amp to do anyway but I figured I would mention it). When I unplug one of the RCA's and leave the other connected it has a higher pitched whine that goes through the subs. This is the only types of noise I can get out of the amp. It isn't a matter of a connection issue outside the amp, as I have direct swapped to another amp that works twice to make sure nothing is wrong. All of the 30 amp fuses look fine, I opened up the amp and nothing looks burnt or anything like that. Nothing looks out of place or bent over, it actually is one of the better put together amps I've seen but I cant seem to figure out what is wrong with it. Any ideas no matter how far fetched is much appreciated.
