sounds like you got a loose wire, a crappy amp, or your amp's circuitry is overheating forcing a thermal shut down. amp getting enough air down there?
oif your amp were shorting out, you would be blowing fuses, and possibly damaging your trucks electrical system.
for added safe measure, apply some silicone to the screws that stick out under the truck to seal it up good.
