    Hifonics..amp comes on, but no signal to subs??? HELP!

    Hey my buddy is a member over here his username is TTsquared100...anyways he has a hifonics bx1500d and one day he turned on his car and his subs would not play, the amp is on it is not in protect but the subs just were not playing, checked all wires everything was fine so we think it is something wrong with the RCA inputs on the amp...He got a new amp anyways so I took his Hifonics and put it in my car last night, same problem. Amp comes on fine, but the sub just does not get a signal...so Im guessing this has to be a problem with the RCA inputs on the amp? What do you reccomend? What should I do to get this amp working?
    thanks

    take off the cover and look at the PCB, if the inputs are burnt or lost connection, you should be able to tell.

    -or-

    Just take it to a local electronics shop, have it fixed, and sell it.

    What the f00k happened to this place?

    to test to see if the inputs are working... run rca's from radio... to input... then from the output... to the input on another amp... if that amp gets signal... nothing is wrong with the inputs...

    What type of electronics shop? I would rather take it somewhere to get fixed rather than looking at it myself, I wouldnt know what to do with it...do I have to find a car audio shop that does repairs? or a computer place? Or what?
    Thanks

    bump...anyone know what kind of shop I need to take this by to get it fixed? It has to either be the RCA inputs or the speaker wire terminals...

    Yes, everything is set fine like i said, the amp was working perfectly for about 5 months until now. Like i said, it comes on and is not in protect or anything, thats wut makes me think it must be the RCA inputs or speaker wire terminals, I just want to know where I should take it to get it fixed. thanks.
