Protection Light My amp has a solid protection light.  I have tried disconnecting everything and reconnecting it.  Its not the wiring I have tested all the connection Power, Ground and Remote they all work.  I hooked the amp up directly to a test battery and ground connection and it still gives me the protection light.  Is there any way to reset the amp?? would that fix the problem or did i just break the dam thing and i need to buy a new one.  Either way I would be greatful for any help.

The amplifier probably was being overdriven and went into protection mode to prevent the output stage(s) from getting smoked. The amp will have to be opened up to make repairs and get it working again.

First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short.
If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec.
Please let me know if you have questions, and thanks for using Fixya.

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 . Please check speakers prior to connecting another amp. .A thumbs up would be greatly appreciated if this answer is helpful to you

sounds like the amp is in protection mode. try disconnecting the subs and see it the light changes to green. if it does then the subs are your problem. if the light was allways red while it was working then the subs may be disconnected inside the box or have gone bad. try using a diffrent speaker and connect to the amp.

Hopefully you have warranty . Send to Rockford Fosgate for repair .A thumbs up would be greatly appreciated if this answer is helpful to you.

disconnect the power wire from it for a minute then reconnect.

Make sure the speakers are wired to an ohm load the amp can handle to prevent protection mode again.

Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.

i had a similar problem with my amp (although a different brand). Check you ground connection and make sure it's not grounded to metal with paint covering it. This is NOT a solid ground connection. You must remove the paint then reconnect it. Without a solid connection to ground, it cant run for very long without going into protection mode. Hope this helps

Hello nfox1987,

First you need to determine if the amp is defective or if something else is causing it to go into protection, most often a short in the sub or amp wiring.

Disconnect the sub(s) from the speaker output terminals and the RCA inputs from the head unit, and test if the amp powers up OK. If it does, the problem is in the sub(s) wiring or voice coils, or in the RCA inputs to the amp. Reconnect each one-at-a-time to determine exactly where the short is and repair or replace the defective wiring or unit. If it doesn't power up with the inputs and sub(s) disconnected, the amp itself is most likely defective.

Hope this helps.

Disconnect all speakers, then turn the amp on. If there is no internal problem with the amp, it will go green. If it does go green, reconnect your speakers one at a time with the amp off then turn it on. when you connect the speaker that's causing the problem, the amp will go into protection. At this point, it's one of two things, a bad speaker wire (screw thru it or touching another terminal) or a bad speaker(burnt voice coil) to test that wire, disconnect the wire at the speaker and turn on the amp, if it's still green, all's well in the wire department. Meter the speaker with a multimeter on resistance, if it's blown the meter will read 1.... If you don't have a meter, connect the speaker that's having the problem to the other channel and test again, if it goes into protection, you've got your answer. Bad speaker. Hope this helps
