buy a new cd player that wont do that

because it takes 30 mins of full volume for it to turn off I'm gonna stick with the internal amp is overheating and shuitting off

think of an amp as a motor

do you ride @ redline for 30 mins? what do you think would happen? maybe there wont be a problem. Now imagine that if you were doing that voe hills and randomly adding a 50lb bag of sand to your trunk

what now? well the motor wouldnt be happy

now make it a really shitty motor, like an anemic 1.3 out of a geo with 100k on it

wont last long

stock cd players, 90 percent internal amps are the same way, not exactly meant to play loud and for long periods fo time.
