SOURCE: amplifier problem
try this it may help do you have a frend that you could swap amps with just to test (put your amp in a working system to check yor amp) as it could be a number of things it could be no out put from the head unit or a break in the rca cables or dare i say it but the amp could be blown it may even be speaker cable from amp to sub or the remote not working have fun !

It's rare that 2 channels will fail simultaneously, are you sending 4 signals to the amp or just 2?
If you are sending just 2, perhaps the problem lies before the amp in the cabling to it, or the output from the headunit. If you are sending 4 signals then there may be a fuse in the amp that drives 2 channels out of the 4. Of course this may be the case should you just be sending 2 signals.

ok on most amps there are two sets of wire ports one for speakers & one for +12v,grd & 12v remote start if you look over each port it will say what port is for what wire if it is in a connector it gets slightly more complecated what you do is with a vm check from wire to chassis ground [like seat bolts] 12v with key off when you cet power isolate wire then turn key on till radio comes on then do the same test for 12v isolate that will be remote start then turn key off &check from the first wire to other wire for ground to find speaker wires connect a regular peace of wire to chassis grd & touch the wires you will here the speaker pop be sure not to hold the wire on long cause it will blow the speaker

Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.
