Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty .
.A thumbs up would be greatly appreciated if this answer is helpful to you

Have you tried new rca jacks????? If not try them...If the problem persists, it may be the preouts on your stereo.....I have ran into that problem with a few stereos, especially pioneer.....thumping sound with the sound turned down, weird sounds etc.....If it still does it maybe try one of those line level converters.....(i used one in my last car when my preouts were messing up....)I just spliced into my rear outs

The amp will go into protection mode when there is a short in the speaker wires or the amp was overloaded. Verify that none of the speaker wire connections are loose at the back of the receiver or at each speaker. And verify that none of the wires are making contact with each other.

If it is, then remove the speaker wires and connect them again properly. After disconnecting the speaker wires, unplug the amp for 10 to 15 minutes. This will make the overload protection back to normal

Try this and let me know. I hope this would solve the issue

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

Hi Hector, if all the wiring is connected properly, you then mite have a problem on the circuit board, or with the subwoofer itself. While its switched off try moving the switches one or two times just in case there is a dry contact. Next would be to take in the unit for an independant bench test before opening the unit. Cheers.

About all you can do if your really wanting to "fix" it, is tear it apart & completely recoil both voice coils.
Otherwise you can just run it on the one good side like a single voice coil sub.

If going sealed I would aim somewhere in the 1.5 to 2.0cuft area. That sub can go in a 1.0 cu ft box to 2.4 depending on the room you he the bigger is usually better for sound quality

First, that amp, has too much power for that sub. Even though it isn't really outputting 2500 watts, (realistically putting out 650 watts). That sub is only rated to handle 150 RMS, 300 Peak, 1000 watts will blow that sub very quickly.

First thing you need to do is find a sub which better matches the output of your amp.

The second thing, you need to make sure that your vehicle's electrical system is able to handle the additional current draw.

Address these things before you install your gear.
