Rockford Fosgate punch speakers, alpine deck (this years model, brandy new), arc audio 4100se amp, 2- 10" JBL subs. Basically, rear subs and amp aren't on at all. Checked the wires going to the amp from the subs and vice versa, they're fine. There is no power at the amp, I can tell because the light isn't on at all. I installed the radio a few months ago, everything was fine.. Now as of a few weeks ago the subs and amp haven't worked, and randomly my rear speakers won't work but they're hooked up.. I checked the fuses on the amp, they're fine. Any fuses by the kickpanel that would maybe cause this if they're blown? I started to check but it started snowing so I had to stop and cover the car.. Any help would be great.
