Bad or shorted voice coil on sub maybe. If you have two subs try them one at a time to see if it goes into protect mode. Whatever sub does it is bad.

SOURCE: amp in protection mode

like many other problems people have with amps it is usally a ground issue, grounds have to be in very good spots especially with high power amps, move your ground to a different spot, with zero guage wires really is all you need, double grounds would be inopropriate here. hope this helps

SOURCE: Amp goes into protect mode.

I would definately suspect wiring. If you can use a volt meter. Put it on the b+ to ground and see what the reading is should be 12+ then try the ground to remote wire should be 12+. If it drops below 12 volts when car starts. Recheck wires for loose connection. Also double check the wire you have the remote wire connected to. You might even want to disconnect from the amplifier and use a jumper wire from the positive terminal on the amp to remote on the amplifier and see if it stays on then. If it stays on you will have to find the loose connection or find a different wire to get remote power.

SOURCE: amp staying in protection mode

No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.

SOURCE: amp overload protection mode

it sounds like the ground is bad to begin with and check the positve cable for oxidisation on the battery terminal and at all other places that the power wire is connected to

Hey I have a rockford fosgate t2500bdcp-1 when ever the bass is about to hit the amp goes to protect mode and comes back on

If you can tell that it is about to hit and the amp goes into protect mode, the amp is being over driven on the input.

My bass cuts when playing but goes back on after a few seconds.

that because you have a loose ground to your amp or not the right size wire but check your ground on the amp it will overheat and turn off to protect itself .

My stereo went into protect mode after i was wiring a new speaker and may have touched two speaker wires together while the car was on...i reset the stereo as instructed in the manual and now my bass hits...

turn radio on and unplug speakers one at a time if the problem goes away once you unplug a particular speaker, then there lies the problem. it sounds like you have a short. Unplug the rca's going to your amp one at a time also.

JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.
