First disconnect the subwoofer wires from the amp, turn the car off and back on...is the amp on? If so your subs are shorting it out, either from a frayed wire, or blown subs.
If it is still in protection mode, check the fuses in the side of the amp.

Stuck in protection mode tried everything voltage good wires good ground good open/close button dosen,t help me at all love amp please help


everything you've tryed is useless(with respect) because amp has shorted output transistors one or more and amp is in protection mode to protect your amp from further damage.take it to repair shop or try to locate blown transistor yourself.good luck

Amp stuck in protect mode.


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. Double check all connections. Good Luck.A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

My amp is protecting unessacarily when ran at 2 ohms


are you factoring the ohm rating from running them parallel?

2 x 2o subs parallel = 0.5 ohm (lowers ohm's)

2x 2oh subs series = 4 ohm

IT is posable that you are calculating the ohm rating fine, BUT some SUBS can reach lower ohm rating while hitting bass- i didnt know this till i had a rather insane sub that would dip to 1ohm while hitting hard bass causing my amp to go into protect mode.

My red light on my amp is on and wont go out


Unfortunately I think you need to get it repaired or replaced .When a protection light will not turn off it is generally caused by an internal short and needs one or more replacement parts for it to come alive again.

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.
