I bought an alpine pdx-m12 to run my 2 kicker l7 from a guy on here and got it yesterday in perfect condition. I hooked it up and it worked perfectly. Drove around all yesterday and worked great. Turned them on today and the hit a few times then stopped working. The amp isn't turning on. I switched the remote wire and used the one from my other amp that was still working and still nothing. All the fuses are good on the amp along with the power wire. It is using the same ground spot as the other amp that is still working. What could it be? Did the power wire go bad? I didn't see any protect mode light on the amp to see if it was in protect mode.
