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 amp isn't fried more than likely... if you have a 2 ohm load going to it it will kick the amp into protection right away no doubt... you need to check it out what you are presenting to the amp go to and to the subwoofer wiring diagram section and you'll fix your issues easiy.

Power winow wiring diagram for 2004 venture

Click on the link.
Check the wire harness on hinge side of driver door. Probably has a protective rubber boot, see if you can pull boot back far enough to get at yellow wire, key on, use a test lite and probe yellow wire, see if there is voltage.
At the lower part of diagram, see black wire, terminal G, that is ground, find that in wire harness and check it. You can use a test lite connected to battery voltage, probe the black wire, if the lite comes on, at least the ground is good enough to turn on the test lite. Because you open and close the driver door so much, sometimes those wires break.
When probing any wires, cover the hole with fingernail polish or something, when your done.

I can only help by telling you to check voltage and ground circuits. You check voltage by using a test lite, see the fuse in diagram, not only check the fuse, check the fuse circuit for voltage.
To check ground, you can still use the test lite, one end comes from voltage, the other end you touch to ground wire, the actual wire not the insulation, if the lite comes on, at least you know the ground is good enough to turn on the lite.
You can see voltage wire color coming from fuse. The ground wire not in the picture, black with yellow tracer.
on the hinge side of driver door is usually a wiring harness going into the driver door, probably has a protective covering, move cover back far enough to find the wire colors you want to check.
You open/shut driver door so much, sometimes those wires may break?

I turn on the powerand then it says status for a couple of flashes and then it say protect once and automaticlly shuts down

A precise make and model might yield more-specific answer.

Generally speaking, an amp protects itself from heat, shorts and overloads.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

When the protect lite comes on and the sound cuts out , what is it protecting ? the speakers or itself? thank you.

"Protect" is saving both really - but primarily the amplifier. The protector guards against shorted speaker wires, damaged and mismatched speakers, etc. If the amp is allowed to operate for a long enough time in this condition, permanent damage may result.

Usually, the lower the volume the amp is operated at will allow it to be played longer before the protect indicator comes on again. If played at a high level of volume, the protector will likely activate very quickly. Sometimes, damage to one or more output transistors seems to prevent the balance control from working correctly. You may find that you can only play the right channel at normal volume and the left is significantly softer - or not audible at all. This can be a fairly expensive repair - depending on the number of transistors to be replaced. Some factory service centers offer a flat rate repairs for this indication. Shipping these devices can be fairly costly however.

I hope this helps.

On this advice given by skinnman 33, it says "check your ground." How do you do that? I am experiencing the same problem with the led protector light coming on. It will play for about 3 minutes or so and...

When we say, "check your ground" all we mean is to look at the ground wire that connects to the amp and make sure it's adequately grounded. What I do is bolt it to a car seat bolt, that is the best ground you can get(called chasis ground). Try that and if you're still experiencing issues, troubleshoot it by removing one signal wire at a time. signal wires are the speaker and auxillary wires. Sometimes a short on these wires will cause the amp to go into protect mode. If you removed all your signal wires and all you have left on the amp is the remote, power(12volt battery) and the ground and your amp still goes into protect mode, then there's a short in your amp. good luck

Protection lite and over current lite stay on

Sounds like a problem with the coils. Coils are known to short-out during periods of high-use. This happens when the insulation between wires break down and allow for a path of lower resistance for the current to travel. If this is the problem, you'll have to replace the coils in the amp which is a weekend job, but completely do-able. Hope this helps
