More than likely, your speakers are wired up in such a manner that they are creating more resistance than what the amp can handle. That's usually what puts amps into protect mode.

Car speakers should be 8ohm's resistance, but if you're bridging and running a dual voice-coil sub or two subs in series... you could have inadvertedly wired it up so the amp is seeing 4 or 16 ohms of resistance? (depending on which way you went)

Try removing the speaker wire completely, then turn the amp/car on and see if it still goes into protect.

Trick to reset pb1217x when protect light comes on?


if the amp is shutting down and the protect light is coming on you just have to let it cool down because it is getting to hot, sounds like you are pulling to many OHMS for the amp. if you are running your speakers bridged you can try running them unbridged (parallel) and that will drop the OHMS letting it run cooler. or you might have to try a different speaker/amp combination speakers might be to many ohms for the amp.

Ok so my Nitro BMW - 481 2000w amp was working and then i came back the next day and the red protect light was on its been working for weeks but now it has the red light.


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.

Hi i bought an amp and sub package a few weeks ago and i was testing it out the other day and pumped it a bit and all of sudden the sound wentt there was no bass. so i checkd the amp and the protect light...


IT SOUNDS AS THOUGH THE AMPLIFIER MAY BE DAMAGED AND AS IT WAS DAMAGED, IT CONTINUED TO CHANGE AS IT WAS GOING OUT, HENCE THE DIFFERENT STAGES OF LIGHTS AND SYMPTOMS. WHAT YOU WANT TO DO IS TO SIMULATE A BENCHED CONDITION, INDEPENDENT OF YOUR INSTALLATION. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION AND YOU HAVE VERIFIED THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN THE AMPLIFIER WILL NEED TO BE SERVICED. ANOTHER PROBLEM WHICH IS A LITTLE RARE, IS THAT SOMETIMES THE RADIOS REMOTE OUTPUT WILL SAG BELOW 11 VOLTS AND THE AMPLIFIER WILL NOT TURN ON. IF YOU CANNOT MEASURE THE REMOTE LEADS VOLTAGE, SIMPLY DISCONNECT IT AND TEMPORARILY INSTALL A JUMPER BETWEEN THE POSITIVE TERMINAL AND THE REMOTE TERMINAL OF THE AMPLIFIER AND THIS SHOULD FORCE THE AMPLIFIER ON, BUT IF IT DOES NOT, IT WILL DEFINITELY NEED SERVICE, AS YOU HAVE TOTALLY SIMULATED A BENCHED CONDITION THAT IS TOTALLY INDEPENDENT OF YOUR INSTALLATION. ANOTHER NOTE OF CAUTION, IS THAT YOU MAY HAVE EITHER WIRED A TOO LOW IMPEDANCE LOAD OF SPEAKERS TO IT AND CAUSED IT TO FAIL OR EVEN THOUGH IT WAS THE CORRECT IMPEDANCE LOAD, THE SPEAKERS MAY HAVE BEEN DAMAGED AND WHEN THE VOICE-COILS START TO MELT, THEY WILL SOMETIMES TAKE OUT THE AMPLIFIER. SO AT ANY RATE, IF IT IS IN FACT THE AMPLIFIER, MAKE SURE TO CHECK THE SPEAKERS BEFORE REINSTALLING THE AMPLIFIER, AS YOU SURE WOULD NOT WANT TO REPEAT THE PROBLEM. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Vx4004 red protect light is on


Try disconnecting all power and reconnect and if prob. persists mosfet chips are bad on the heat sink. Usually from dropping the ohm load to low.

Protection light on Kicker ZX700.5


Considering you just bought it, the amplifier itself is probably not the issue. Small chance it is, but we'll go with that a last resort. Have you hooked it up without any speakers connected? Does the light still come on? Describe all the connections you have made to amp (what came from where, and what terminals it is connected to.)

There is no reset button. If you disconnect all of the speaker wires from the amplifier's speaker terminals and unplug the RCA cables, does the protect light still come on (I assume that you've already replaced the fuse)?

was the amp hooked directly to the box? You probably rattled the power connections from the circuit board like I did on a PT 800 watt amp.but check amp fuses first.
