Re: my amp goes into protection mode at high volume
Hi does the amp return to normal operation once the volume is lowered? If so it sounds like the amp is seeing too low an ohmage due to the way the subs are wired & they are drawing too much current so the protection circuit intervenes to prevent damage.The minimum ohmage this amp must be operated at is 2 ohms so if you are running at 1 ohm this will cause the problem you are experiencing. Cheers, acbva.

Do you have a capacitor????? If not, when its up loud and hitting hard it might be going into protection because of a voltage sag....If it goes below 11.8v they will usually do that.....Get a multi meter and put on the hot and ground of your amp when its playing loud and see what the voltage is dropping to.....If its going below 12v, thats your remedy...gd luck....
Sounds like it was playing? If it was your voltage dropped and the mosfet power supply got toasted. These amps are notorius for burning up at low voltage. Kicker did not put a low voltage shut off on it.,
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.
Protection LED on, no output? Amplifi er is very hot = thermal protection is engaged. Test for proper
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around
the amplifi er. Amplifi er shuts down only while vehicle is running = voltage protection circuitry is engaged.
Voltage to the amplifi er is not within the 10–16 volt operating range. Have the vehicle’s charging and electrical
system inspected. Amplifi er will only play at low volume levels = short circuit protection is engaged. Check
for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.
No or low output? Check the balance control on source unit Check the RCA (or speaker input) and
speaker output connections.
If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low when the amp goes into protect.
If the voltage is OK, you need to check the speaker wiring and the speaker(s). Try it with a known good speaker if possible to see if the amp works normally.
How long will the bass play before the amp kicks into protection mode and how loud are you listening to it? I've noticed with my amps that if they don't have enough air flow they will get hot and kick into protection mode. They will also kick into protection mode if you are running it at more than it can handle. Check your adjustments on both your amp and the head unit. Make sure you are not running more bass than the amp can handle.
