[QUOTE="devin171moto, post: 8704270, member: 679009"] THX ONE gave you good suggestions. sorry if I just add something common sense, I don't mean to give dumb answers but sometimes I've found I brain fart and troubleshoot for hours because I missed something stupid. one time I almost returned an amp because I was getting power input but no output on the mono speaker wire connections. turns out my dumb ass had the sub turned off at the radio if you have power on remote and 12v I would remove the speaker wires from the amp and play with the gain and test if you're getting voltage out. If you aren't and you have an aftermarket deck hooked to RCA'S, double check your radio settings that sub woofer is on (depending how you wired your remote. you could still get remote power with RCA'S not putting out a signal. ) if that's good. check for voltage on the RCA'S if using high input then just check if those wires have voltage. try hooking a fresh set of rcas to your phone or another source with an adapter and see if you get voltage. make sure lpf is at 80 and ssf all the way down. if that doesn't fix it then you're gonna have to pull the sub and check the ohm readings of the coils. if the coils are far off of their intended resistance their blown. if the coils are good, the last guy could also have the box wired to a load that your amp doesn't support. look up how to wire your specific sub to the ohm load that your amplifier is rated for. and test again to see if you get sound. if none of that works I'm not qualified enough to help you. Don't know much about bad amps. never had one. [/QUOTE]
