The only thing to try would be to remove the sub wires form the amp and see if it still goes into protect. If it still goes into protect with the subs unhooked then the amp will require repair.. If it doesent go into protect then check to see if you have a shorted subwoofer. also make very sure that you have a good clean bare metal tight ground connection to the body of your car. People forget that step all the time.. Did you do your setup with the correct ohm load? Most of these amps will fail if the subs are hooked up incorrectly(too low of a ohm load). If the amp has a lowest possible ohm load rating of 4 ohms... but you have a pair of 4 ohm subs.. you hook them up togther at the amp.. both positives togther- two negatives togther.. because it "bumps harder" that way.. Then you now have a 2 ohm load on the amp... The lower the ohm load you put on a amplifier the more it will output. The problem when people do this is that the amp outputs more current then its internal parts are rated for and the output transistors (usually) fail.. most amps will not fail if installed correctly.

My thermal light on my 1000/1 amp comes on too often

This means your amp is in "protect mode" this light indicates that your amp is having a short circuit or loose of power.
Check your cables, if they are secured & no exposed wire And most important of all, check your voltage reading, it must be above 12v.
Loosing voltage in car audio is the number1 factor of heat/thermal problem & fire.
When an amp looses voltage, heat builds up inside it. Too much heat will make the amp be on "protect mode", excessive voltage drop will cause the amp's circuit board & other parts to be burned.
So, always watch your Voltage, either with a plug-in volt-meter or with a fuse holder & voltmeter.
Hope this helps.

I hooked up 2 capacitors into my amp and every time I put power to it the amp shuts off and 10 seconds later a red light comes on for 5 seconds and the amp don't turn on, basically it goes into protect...

Well, I have no idea why you would have two capacitors on a 500 watt amp but, did you charge the capacitors? Have you tried the amp without the capacitors? What size power wire are you using?

JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

AMp does not display any LED read out

Amps have a part inside that is made to keep the channels equal. The problem is that when there is nothing hooked up to the second channel, then this goes bad and goes into protect. It is really hard on an amp to use just one channel.

Light

The red light indicates that your amplifier is in protect mode. Amps go into this mode if there is something wrong with the setup of the system to prevent fatal damage to the amplifier circuitry. This is bad thing since the amplifier will not function until the problem is solve and it can remove itself from protection mode.

Amplifiers can go into protect mode for many reasons but one of the most common is incorrect mounting. Is your amp sitting on the metal of your vehicle? Is it bolted down and screwed into the metal of the vehicle or your seat? The amp should never be touching any sort of metal. Only the ground should touching the metal of your vehicle.

Speaking of grounds, many people often neglect proper grounding which can cause an amp to go into protect mode. Do you have a solid ground? Is the wire less than 3 feet long and directly connected to a non-painted metal part of your vehicle? Is the ground wire the same gauge as your power wire?

These are just a few reasons why an amp can go into protect mode. You can find more information here. Or simply google for why your amp is in protect mode.

Thumping speakers - no power light is on - wired correctly

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

This could cause from different issues.

1. Check if there's any voltage leading from your ignition to the remote cable on the AMP. If you have voltage on the ignition check the fuse that connect inseries on the remote cable.

If the fuse ok you might have other problem in the Audio Output stage.

Good luck.

Protect Mode

Is it doing this while you have it turned right up? Most systems have protect mode because you are trying to draw to much power or amps through them. Are you trying to run to many or to large of a speaker through them all systems have rate output if you try to exceed this they go into protect mode so you don't blow the amp.
