Hi, I have a Kicker KX800.4 that has the power, ground, and remote all hocked to it. I have had this in the vehichle before, it was taken out and placed in another vehichle and now put back in the original. Every time I try to turn the amp on, the protection light comes on. It has never had a prob before and I rechecked all the wiring with a test light. Any ideas on what may be the problem or any test I can run to double check anything. Any help would be appreciated. Thanks!

you should have an output on the amp running the 4 6/8's connect to kicker inputs hope you got a cap(capacitor)to run this set up and a good wiring kit.if so just run all the power cables to the power block feed the amps,ground them and don't forget the remote wire and you should be fine
Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.
If it is the amplifier that is shutting on and off:
Check to make sure the power and ground wires for the amp are secure, with no fraying, knicks or exposed wire. Check your fuses and connections to make sure everything is correct.
Also look at the grounding location. be sure there is exposed metal around the grounding point (paint may cause intermittent power problems).
Lastly, the amplifier's remote wire may be improperly secured to the wiring harness. Check the harness for exposed wire grounding out connections.
If the amplifier is continuously on, the subwoofer may be to blame. Check and double check wiring schematics to ensure correct ohms rating.
1st check all of your wiring, make sure the remote wire is hooked up, check to see it the RCA's are hooked up. I know this sounds stupid, but i've done it a thousand times, check to see if you hooked up the speakers. If you checked all of those and still nothing, double check your ground. Make sure where you have it grounded, you have all the paint sanded away and its a good grounding point. The red light on the top of the amp, its not a protection light is it??
try hooking up only the power ground and remote see what happens if protection light is on then u have a problem with amp if it goes off then hook up rca if still off then hook up speaker wire if it turns on then u have a prob with speakers
TRY TO POWER THE AMPLIFIER UP WITH NO RCA INPUTS AND NO SPEAKERS CONNECTED. IF THIS PROBLEM IS STILL PRESENT, THEN THE AMPLIFIER WILL NEED SERVICE. KEEP IN MIND THAT YOU STILL NEED TO VERIFY THAT YOUR POWER CONNECTIONS ARE SOLID, NO LOOSE GROUNDS, ETC. ALSO, IF YOU HAVE A VOLTMETER, MAKE SURE THAT YOUT REMOTE LEAD HAS APPROX. 12 VOLTS MEASURED FROM GROUND. SOMETIMES A SAGGING REMOTE LEAD THAT HAS LESS THAN 11 VOLTS CAN CAUSE A GOOD AMPLIFIER TO EXHIBIT THESE SYMPTOMS. AFTER ALL, IF THE AMPLIFIER STILL DOES THIS, THEN THE PROTECTION CIRCUITRY IS SEEING ONE OF THE THREE TYPES OF FAULTS WITHIN THE AMPLIFIER AND IS SIMPLY SHUTTING IT DOWN. SOMETIME AFTER WHICH IT TRIES TO POWER UP AGAIN, ONLY TO SEE THE SAME FAULT, THUS REPEATING THE CYCLE CONTINUOUSLY, INDICATED BY THE POWER LIGHT GOING ON AND OFF. LET ME KNOW IF YOU NEED MORE ASSISTANCE....V
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
