do you have a capacitor? What is the rms wattage on the kole amp And the subs? what is the listening condition when this happens? does the subes start to clip or get distorted?

yes i have a 15 farad capacitor rms on amp is 3200 at 1ohm subs r ran at 1 ohm there 400rms i know way over powered but the gain is only maybe a quarter of the way up and it happens when i got the hu turned up they dont get distorted they just hit harder and it sounds like it should sound but when it goes back to normal there no where near as loud

Are the subs Dual Voice Coil? Are the coils wired in parallel? If yes to both questions, the wires between the terminal and the cone of the speakers do break. When they break they do intermittently work. You need to play each voice coil one at a time to make sure all 4 are working. Before trying that, play the amp with only the left RCA cable plugged into it. Then play it with only the right one. Let me know what happens.

As long as it plays with each one plugged in, that rules out the possibility of my thought.

ok i just figured out the problem its my amp went to a friends house he had a old lanzar vibe 800 watt amp i hooked it up all settings down all the way besides the bass boost which is a switch and turned it up and it banged prity good twice as loud as my amp at 4 ohms with gain half way and bass boost all the way up so if anybody has a power acoustik or kole amp sell it now before this happens to u thanks for the help guys will never buy another amp from pa they are junk wasted 300 bucks on a big paper weight lol
