Protection light comes on , was only coming on when i turned up the stereo , now it stays on , all the wires are good and i cracked the amp open and nothing looks burnt


check your gain on your amp. If it gets hot the shuts off into protection mode you are over working your amp. Check to see the way your subs are wired up and see if your amp can handel the load.

When my zr1000 amp kicks on it automaticaly averheats and shuts off it is also hot to the touch what should i do


One great amp !!! I would send it in to kicker. It looks like you may have one or more mosfets that are either shorted or on the way out. Does the amp have any protection lights that may give an indication of the source? Some thing that come to mind are: Shorted outputs, Speaker wires shorted or touching ground, power supply mosfet's

Cut out


rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck

My Amp Keeps shutting off


You need to get an amp with higher wattage. Obviously, your amp cannot handle those two 10" monsters. hehe Nice Subs though :D

Green light on but no sound from subwoofers or speakers


HI...IT COULD BE A BAD THERMAL FUSE NEAR THE OUTPUTS ....OR A COMPONENT HEATING UP TRIPPING THE THERMAL FUSE TO SHUT DOWN... OPEN IT UP SEE IF THE OUTPUTS ARE GETTING REALLY HOT.. IF IT IS NOT GETTING REALLY HOT... USE A JUMPER WIRE TO JUMP OUT THE THERMAL FUSE IF IT COMES RIGHT BACK ON.. GET A NEW THERMAL FUSE DON'T KEEP THE JUMPER ON (USE FOR TEST ONLY) GOOD LUCK

Rockford P550.2 going into protect mode


Does it shut off for a couple of minutes or a couple of seconds? Is the amp hot when it shuts off? Are you sure you have the speakers wired to an acceptable ohm load for the amp? Have you measured the voltage at the amp (across the B+ and ground terminals) to make sure it's not dropping too low on hard bass notes?
