my 4-channel amp is not powering the rear speakers correctly and it seems to be getting really hot. it almost sounds as though the rear speakers are blown. i tried to swap rca's and it did no good. the front sounds fine. is there anyway to test an amp?

 

Maybe a short in the speaker wires?? You could stick a DMM on the amps outputs and see if you get a reading (on the AC volt setting).

How are are your gains?

 

gains are set at about half. what reading should i get at the outputs?

 

i just removed all speaker wire and tested each speaker with each rca. it apears that i have an rca problem! here goes nothing....

 

after all the checking the head unit is faulty. crutchfield is shipping a new one!

 

Thats good you got the problem figured out. So is the HU warrantied?
