Hi i am matt

On my amp the red protect light stays on and it wont let my amp work and when you take out the fuses the red light goes off

  • mmcvay911 Nov 08, 2008

    I just installed 2 older alpine amps in my truck. After trying to fire up my system for the first time, the power lights on the amps both are red. I have checked all my connections but cant get the lights to go green. They stay red whether the rca cords are plugged in or not

    my protection light also comes on, but it only happens when i have the Volume higher and no sound will come out at all.... as soon as i turn the volume to a lower level the sound comes back and the Red Protect light goes off. Seems like there is a short, but how can the short only come when the volume is higher... is it maybe that my battery just doesn't have enough juice?

If the protection LED lights only after the remote voltage is applied (head unit is switched on), the amplifier likely has shorted output transistors. If the protection LED remains lit without remote voltage applied, the amp may have other problems.

Does the protection LED light with no speaker wires connected to the amp and no RCAs plugged into the amp?

Kenwood kac 628 red light comes on and no audio output

The red light you describe on your amp, is the protection mode warning light. An amp goes into protect for many reasons. Here's a checklist.

1st check the fuse (s) on your amp and make sure they are not blown.

2nd check the inline fuse next to your car battery (if you have an inline fuse)

3rd, disconnect the speaker wires with amp on, does the light go off?

4th check your ground, this may be ok if you have tried another amp with the same wires.

5th.if none of these turns the protect mode off, it may be an internal fault.

you may have blown transistors and it is a tricky job to repair and costly.

The Ground wire is hooked up right but the red light wont go off and stay green so the amp will work. It is very frusterating all the cables are the right size its is a 1000 watt amp. I have two 500 watt...

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?

My vr3 amp light wont go green, it just stays red

It is in protection mode, it shuts down the amplifiers power supply so that it does not destroy itself. You may have a shorted output transistor.

What does it mean when the red protection light illuminates

Hi the protection light comes on when there is a problem within the amps. circuitry. Generally speaking the protection light normally comes on when powered up while the amp checks all of its voltage rails so that they all lie within a specific tolerance, when all have been verified to be in spec. then the protect light goes out & the power light comes on. If the protect light stays on then a fault exists within it's circuitry. Cheers, acbva.

Amp is going out.

Have you tried replacing all of your fuses? If that does'nt work check your ground........ I would check all your connections also could be a connection shorting out causing your red light to come on.

RED Port light on AMP?

are you sure its not PROT?
the amplifier is protecting itself from fire because of something.
Disconnect the subs. and turn on.
if it comes on normally, the subs are at fault and will need attention. If the light still stays on, you hafe probably blown an output on the amplifier and it will need repair.

My sony xplod 1000w xm-1652z doesnt work anymore

First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.

If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.

Overhaul light (red) stays on!

This is not a ovehaul light. It is called the protect indicator. It kicks in when the amp detects a fault on it's output. Disconnect the speaker / sub. Power up the amp and see if the light goes out. If it does you Sub is toast and needs to be replaced. If it stays on then the amp is done.

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.
