If it works OK when hooked up in stereo but not bridged, then you would look into the impedence as a problem. If it doesn't work when running stereo or bridged, then you may have a fried transistor/MOSFET in the output. If stereo is OK and bridged is nogo then try using an 8 ohm impedence when bridged.

If you're bridging the amplifier you can't use a speaker or speaker combination under 4 ohms. If you have 2 4-ohm subs, or a dual voice coil sub that you're trying to run with the bridged amp, that may be your problem. The screws aren't designed to come out of the holes; they're supposed to just loosen or tighten the terminals. A loose wire in a terminal won't cause a protect light on the amplifier unless the wire is shorting to another terminal or to the case of the amp.

Cyclone ca-594 amplifier

The protection system will come on if for example the speaker wires are touching, or there is an overload in the system. If you can't get it to clear, then suspect a power transitor has failed, causing a short circuit.

How do you reset nitro amp that is in protect mode?

If the amp is in protect mode, then there may be a speaker wire that is shorting out or you may have a bad speaker...you can test this by completely unhooking the speakers on the amplifier and then turning the amplifier on...if it comes out of protect mode then you will need to find out which speaker is bad...if the amplifier does not come out of protect mode when you turn it back on then there is a problem inside the amplifier and you will need to take it to a service shop for further diagnoses

I have a ma audio hk-602sx and my protect light wont go off and somthing is clicking inside and as it clicks the protect light blinks.

Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech

Installed lanzar 266 amp yesterday it went in protect mode on a song and now everytime i turn it on it is in protect mode

most commonly that means that somewhere there was an arc in the electrical either the pos or neg going into the amp or rcas or its the speaker wire from the amp to to the sub itself look especially for little wires touching opposit polarity wire (like a little +wire has moved and touched a - wire)

Xplod XM-554ZR Car Audio Amplifier: powr/protect light comes on red not green...

Hi, disconnect all speakers from unit and try again - if red light still shows then your amp has died.
If the light goes green, then start testing for shorted speaker/wiring. This includes speaker wiring to vehicle shorts - there should be an o/c reading on your meter

Protection light comes on

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. Dou .A thumbs up would be greatly appreciated if this answer is helpful to you. protection-light-comes-lv2kkrmxrai4iihdvw4m3np2-2-0.jpg

Protect light comes on, no power

Hello patrick_h_mi,

You'll also need a remote turn-on source for the amp to operate. Normally, this is a blue or blue/white wire from your head unit, but for test purposes, you just need 12V to the "remote" terminal on the amp. The amp should power up without speaker inputs or speaker connections, but it is not recommended.

Hope this helps.

Sony xplod amp(XM-1652Z ) power/protect light

if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.
