I can't believe how flipping switches back and forth and back and forth is good for the power circuits of an amp. Circuits, and allt he resistors and capacitors in them don't like surges or power, let alone multiple ones.... Home recievers get more wear from being turned on, then being used.

lol.......i dont sit there and flip it on and off on and off...its just for when i come home from work 2 blocks away i ike to listen to music a song or two...and if i run the subs my car doesnt start in the morning...so now i did it the other night and my car started...i was pretty happy...lol i might switch it back once i get more things i can use the switch for...!

It sounds like it could be several things. Possibly a current problem, but I doubt it for that long (got a cap?). Another thing is the heat, most probable source. Lastly it could literally be shorting because of the heat itself.

Thanks for the responses. 1st, I don't have dual voice coils. So it is pretty much either bad connection or heat. I didnt think it could heat up that bad only running one small sub and two components. Would dropping the gain down some help it some by not working as hard?

yes it would for sure. as far as heat goes u may want a bigger box. that would relive the back preasure on the speakers which means the amp wouldnt have to work as hard to move them mine ran a lot cooler when i did that

Yeah you should eaither add a fan or heat sink to your amp.... a very easy mod...and definatly check the dimentions on your box.

Overheating is a symptom of a wiring problem, unless you are driving your system to the limit as in a SPLcompetition, or it is in a tight space without ventilation.
Make sure you have a good solid ground connection and check your speakers & wires.
I once had a sub where the flex leads from the terminal to the cone would touch intermittantly and shut the amp down.

Silver my amp on my 6x9s overheats and its out in the middle of the trunk...and everywire is in good...its just a matter of if you play it too loud it overheats...im guessing there is no wiring problem since it does work good at the beginning...

All amps will get hot, but if it is constantly shutting down there is a problem. Could be that the amp is too small for the job.
