Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.
If the fuses are good , this could still be a prob with amp, check spkrs with a ohmeter(cheap one from the Shack or anyplace) by touching both leads to spkr terminals, disconnect spkrs first.Have ohmeter set to ohms Rx1 and you Test amp out put by connecting two spkrs that you know are good. Good luck and please rate this answer,thanks.
it could have blown the speaker, a regular guitar amp is not meant to handle a bass, you should be able to look into the back of the amp and see if any of the speaker is damaged, or there may be a blown fuse inside the amp, if you check for this please MAKE SURE TO UNPLUG THE AMP FROM THE POWER SOURCE FIRST, and if needed replace the fuse with the exact same type
Check the physical condition of subwoofer to make sure that the surround has not rotted out or been blown away. If ok, then using an ohm meter check for the nominal speaker voice coil resistance to make sure it is within spec. If both of these areas are good then you have destroyed the output stages of the amp(s) driving them. Every 3 db of bass boost doubles the output power. So if you are blasting along at 100 watts and you jack up bass by just 3 db the amp now has to put out 200 at those lower frequencies; go up by just 6 db and you are now talking 400 watts! And what does that do to an amp when you over drive it? You guessed it!
