Here's my 2 cents...

I think its a heat realated issue OR a connection issue.
Trouble shooting tips:

1) Some morning when its nice and cool, turn yor ignition swich on without turning the car engine on. Turn the radio on and leave the volume in mid position. Leave it runing and monitor (by touch) the temperature of the amp in the trunk until it stops producing sound. The amp sould be warm to the touch BUT NOT HOT (this is normal). If it gets to hot within the time you have mention then a short in the amp or the next trouble shooting tip. Keep in mind that amps do have an overload/heat protection circuit built-in. If its not getting hot enough within the alloted time that you have mention, aid it by placing a heat gun or hair drier on the amp.

2) Losing sound to ALL the speakers can be narrowed down to wiring. Start by checking the wire harnest connected to the amp and work your way back. Remove the harnest and check the pins for corrosion or obstruction. Then look at the wires past the harnest for possible chaffing or cuts. If everything looks fine, then turn on the radio and place it in mid possition and shake the wire bundle and harnest by the amp.

If you're only losing sound to 1 side or 1 speaker, then that makes me think its the outputs of either the amp or the radio. The radio can still be the main problem, but these 2 quick tips can help issolate the problem and are easier to get to without opening up the dash.

P.S. If the overload/heat protection circuit is activated then the amp is on its way out. I would definately check for wiring that is causing this anomoly. Only you know your car and any changes its seen.

Hope this helps. Let me know if I can assist you any more.....
