Nikitaaa Posted February 28, 2012 Report Share Posted February 28, 2012 So I reinstalled my amp yesterday and for some reason it's not working now. My amp turns on and stuff so it can't be ground/12v are fine. I checked it with a dmm and there was no output in the speaker inputs. So the problem has to be with either rca's or headunit. My headunit is Alpine CDA-105 and has no on/off for subwoofer output. It's always on, so that's not the problem. And my RCA are new. I'm lost.... Anything else I can check for?

SnowDrifter Posted February 28, 2012 Report Share Posted February 28, 2012 Check the RCAs with a DMM. Set it to AC volts, put the + probe on the pin in the middle, the - probe on the outside and turn it up.

TheNewbie Posted February 28, 2012 Report Share Posted February 28, 2012 (edited) Could it be the outputs?

SnowDrifter Posted February 28, 2012 Report Share Posted February 28, 2012 settings correct on the head unit ... maybe the balance / fader may have turned somehow ... That head unit also has a subwoofer on/off function. Perhaps you accidentally turned it off?
