RF 6x9's keep throwing amps into protect mode ?

I immediately turned the deck off, pulled over and popped the trunk. Touched the amp and it was warm to the touch but not hot by any means. I got back in the car and turned everything back on, backed the vlm on the deck down by about 15. Rode around for a little bit more then slowly started turning the vlm back up. At this point the speakers cut out all together. Checked the trunk and the amp had been thrown into protect mode. Turning the deck off and back on makes the speakers come back on immediately. Protect mode again. At this point I drove home and bumped the amps gain down from 4 to about 2. The system played until vlm on deck went all the way up then protect mode again. Bumped gain down to 1.5 and now they will play without cutting out. So the next day my friend brought me another Sony Explode Amp this time 500W. To save a lot of back story the amp immediately went into protect mode when the gain was raised above about 1.5. No smell this time just protect mode. So today I stop by the car st

Sorry, something i forgot to mention, Amps go into protect mode mostly because of low voltage. Meaning, you car should be at approx 14 volts while on and running, with the alternator and battery working properly. While the amp is on, it is drawing amps from your alternator, through your battery. You can see how many amps it uses by adding up the number on your fuses for the amp. If you had, for example, a 100amp alternator, and your amp needs 60 amps, there are only 40 amps left for your car, except it works the other way, your car takes what amps it needs to stay running, and whats left over from the 100 is to your extra electrical devices, when such devices draw more amps then available, thats when you see your lights dim, first sign your electrical system is weak. That, in turn, lowers the voltage provided through the battery, to your Amp. Amps internals cannot operate at low voltages, low being under 12. When they do operate under that, it will cause damage. When it hits 10 volts, thats when you would normally get whats called, clipping, and that is very bad for your amp and speakers. Your amp protects from such disaster. What you should do is look into upgrading your BIG 3, which you can google "Car audio big 3" to see what i mean. Also a bigger alternator is most likely needed, either because yours is to small output in amps, or is failing. A quick fix, which will help but not really solve or fix anything, is a Capacitor, which stores energy for when you need it, that energy is released and replenished quickly, mostly used with a deep bass hit, keep in mind, it is only a buffer, a weak electrical system, is still a weak electrical system, with or without a Capacitor. Something else that will help, is upgrading your cars battery. Yellow top Ultima batteries are a good deep cycle battery recommended for car audio.

First question. At what OHM's is your amp stable at. Then, tell me what OHM your speakers connected to the amp are set to. If those 6x9 are 2ohm and your amp is only 4 ohm stable, you will get your problem after a while. Also, check your grounding. Perhaps your ground wire isnt connected properly to the chassis, or is to small to be suffiecent. Check your power cable, is it fused? Is the connection becomming degraded at the battery terminal? Look up your amps specs, check what guage wire you should be using to power and ground it. Make sure all your speaker wiring arent backwards, meaning make sure a positive isnt touching a negative. Check the amp fuses, make sure none are blown. Replace any that are.
