SOURCE: Amp won't turn on

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp

SOURCE: kole amp in protect mode?

Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

SOURCE: Memphis PR300.2 Amp protect light on

If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

My Memphis Audio amps protect light will not shut off


Disconnect the speakers, power the system up, if the protection light goes off, there is problem with the speaker or speakers, if not check output transistors for leak or short.

Red light flashes on amp when you turn the ignition key.


It really sounds like a grounding problem. Recheck it make sure where it's attatched to the chassis is scraped to bare metal, an you used a clean, shiny bolt to attach it. Also us a voltmeter to check your power wire just to be sure it's not that, you should get 12-15 volts. Also just make sure none of your fuses are blown. And Use the voltmeter to check your REM wire, your should also be getting 12-15 volts there. If this doesn't fix your issue i'm at a loss to explain it..... Buy a new amp, and don't buy Boss, i've had lots, and lots of problems with them in the past.

Amp Issues


1800W peak output at 2 ohms

4 AWG power/ground inputs and RCA pass through

It is going into protect mode for a reason.
Disconnect the subs and turn everything on again. If the light comes on, the problem is internal and will need servicing by a technician.

Amp hook up


If you are referring to a warning light on a car, unless you knicked a wire that caused a warning light to come on. It shouldn't matter if you have an aftermarket amp. If you are referring to a warning light on the amp. Make sure that you are not under driving the impedence and not shorting any wires. If you dont have any shorts, then your amplifier is probably done for. Because you might have a short internally. Unless it is just in protect mode. I had a memphis amp that went into protect mode, I set it off to the side for a for a week or so and was bored so i hooked it back up and it worked. It still works and that was about 2 years ago. Good luck.
