Heat! Thats what does it to mine.....if its hot out, and you are running them hard....they will shut down and go into a "Protection mode" so they dont over-heat. Shut off the system for a little while and let them chill. Try to let as much air get to the heat sinks as possible....im cuttin holes in my false floor for 2 12v fans to help them out. Theres my info for ya!lol

maybe you got it wired too low? alot of amps dont like being at 1ohm or 2ohm for too long check and see what ohm load your amp is stable at and re-wire your speakers to a better ohm load

I agree with 'Impalawannabe' - HEAT! My RM sedan is black, and before I decided to sell all my car audio, I had 3 MTX 12's, each with a Kicker IX1302 pushing 400 watts RMS to each sub. On hot days, they would cut off on my several times during the day, even if I wasn't pushing them hard. However, it is very possible that you could have it wired too low. If the amp is not 1 or 2 ohm stable, and you wire it that way anyway, it totally overworks your amp(s). What setup do you have, and how is it run/wired?

I have a kicker ZR240 running my insides and a DX700 on my sub (15"L7) you are correct about the ohm load on the amp for my inside speakers, but the amp for the sub hasn't been re-wired (4ohm,DVC=2ohm)
do you think my caps could cause the problems? maybe they may need to be recharged, they were out of the car for a minute.

Maybe the speaker wires are touching someplace. If the connections on your subs are really close together, you might want to make sure. Does the amp have a fuse in it somewhere?

yes, both amps have their own fuses. I'm going to trouble-shoot everything saturday.

How are your amps oriented. Are they enclosed in anything. The amps don't need to be running a really low load to overheat (but it helps). Did they shut down after a longer period of operation on a warmer day? The amps in my car are oriented vertically and they will shut down after about four hours on a 100+ day (summer road trip conditions). 12V fans like Impalawanabe said will solve the problem.
