if you amp is in the PROTECTION MODE its means that there some defective part , like for example the main ICs or TRANSISTORS output might be defective , and thats why its on the PROTECTION MODE , needs to be taken to a expert technician for repair.

There are 4 possible causes for the amp to go into protection mode. Kicker calls it SORT for Short, Overvoltage, Reverse polarity, and Thermal. If the amp has been in and working properly, it's probably not reverse polarity. And if it goes immediately into protection when power is connected, I'd rule out thermal. So it's probably either a short or overvoltage.
1) Start by removing the speaker wires and see if the amp powers up properly. If it does, one or more of the speakers is shorted or grounded.
2) Test each pair of wires with a multimeter set to the lowest resistance (ohms) scale. Measure across each pair and from each individual wire to ground. Across each pair, the meter should read about 3-4 ohms. From each individual wire to ground, it should read infinity. If the meter reads "0" ohms (shorted) in any test, you have located the problem.
3) If the speaker wires test OK, set the meter to read DC volts and measure the voltage at the amp positive terminal. If the voltage is higher than 16V or lower than 9V, you've located the problem.
4) If the voltage is OK, remove the RCA inputs and test for proper power up. If it powers up without going into protection, you have a shorted/grounded input. Replace them one at a time to determine which one(s) is/are defective and replace the cable.
If these tests show all the wiring is good and the voltage is OK, the amp is probably shorted internally (most likely an output MOSFET), and requires service at the component level. You need to take it to your local audio shop or send it to Kicker for repair.
Hope this helps.

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.

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.
