My amp worked fine for a year or so, and then one day the power started cottuing out and then randomly coming back on. I cleaned the battery terminals and the amp worked fine...until now. I had the same problem again, so I cleaned the battery terminals again, and the amp wont come on this time...please help!?!?!
make sure your fuse is 100% working by the battery. Mine started to get a weaker connection and one day, it shut off altogether and wouldn't come back on. Also, as Brett said, it could also be your ground.
Ok, I cleaned up my ground and my amp worked again. Then, this morning it didn't work anymore. I tried cleaning my ground up even more, and it still didn't work. Also, I have another amp grounded in the same spot, ad that amp is working fine. My fuse looks brand new.
