I have a dub2502 amp with the red protection light on and will not go off. The amp is a 1100 watt peak amp @ 4 ohms and my sub is an Audiobahn 1100 watt peak, 4 ohm. wired perfectly. so how do I fix the...


The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.

The protection lite comes on when amp is given powerand sometimes it does not come on but it is still not getting any sound its not my wires they all work for any other amp tell me is my amp fried


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. Sounds like you are overloading the amp. Please check speakers impedance. .A thumbs up would be greatly appreciated if this answer is helpful to you

The indicator light on the amp is staying red in protection mode how do i get it out of protection mode?


Check your manual, sometimes you have to take it back in, depending on the protection. Sometimes you have to change up the fuse. Is there enough power going to the amp, or to much?

My amp lights up gives one note then powers down if you directly hook up the remote it comes on and emidiatly shits down


Sounds like you have overheated it one to many time and one of the mosfets is fried. The main cause to amp failure is over powering it. Turn it up to loud for to many times and it will prematurely fail ever time. Also check you speaker connections. If you have speaker wires grounding out it will cause you amp to go into protect mode. Also try disconnecting one side or the other. Maybe you have one speaker that is fried and causing your amp to shut down.

JBL Amp P80.2 - Random output failure


i had an amp that did that for a while before frying. its possible that it could be overheating causing it to go into protection mode which can be fixed with a cooling fan or remounting it somewhere else so it can get some air. it needs to be mounted in a way that it will have at least 1/2" clearance under it so it can have plenty of airflow. the other thing is you may be putting too much of a load on the amp causing it to go to protection mode. check and see how u have the sub wired and if the amp is stable. if u have the sub wired at 2ohm for more power output and the amp is only stable at 4ohm, then the amp will overload and cause the problem your experiencing. thats what happened to my amp. i had it wired for more than it was stable for and it fried

If the protection light is on, the amplifier likely has shorted output transistors. To eliminate other possible causes, read through the following page.

Amp stuck in protection mode.


check to make sure your ground wire is attached to a clean metal surface no more then 18" away from amp. check all wires to ensure none are touching other terminal. all else fails remove one sub and see how it play, if its works great switch subs. could be a defective amp. if it is the amp and you payed for it with a credit card or bank card you can do a charge back from the bank to get your money back if the store wont replace it. thell the bank "you want to do a charge back cause it wasnt as discribed).
