so tonight i was up in the mountains and i noticed my amp had died.... if the radio is on the subs make a clicking sound about every 5 or 10 seconds the sound is the same if the volume is at 4 or 40 and does it even when you turn the the sub output from the head unit. only stops if i turn off the radio. the power lights on the amp say protected (its light) and the power and othe light go on and off like every 5 or 10 seconds. i tried unplugging the wires and putting them back in, all my fuses are fine so i do not know what it could be, my next idea is to unplug the wires going to the subs because i think the amp may have fried the subs and its causing a short.
does anyone have any ideas of what could be wrong?

sounds like the amp might have toasted the subs. either that or your amp may be overheating, but if that were the case the amp should just shut off and you wouldn't be seeing the power lights on. suggest you find a buddy with an amp and drop his in real quick to see if it's your amp. if you're still getting the same prob, try wiring in another set of subs and see if you have sound. hopefully you've got a bud who's willing to let you do a little troubleshooting with their subs/amp

Sounds like an overheating amp.
Could 'possibly' be a bad ground.

well, i tried another amp same thing.... my ground is def good i think the speakers are fried, when i turned it up real high they used to start smelling like burning electrical stuff so i figured they were gonna burn out eventually

There's a real easy way to test your voice coils to see if they are fried. I have found that simply pushing on the dust cover of the speaker to make the speaker throw can tell you a lot. If there is any resistance felt (physically) then your voice coils are going significant resistance means they are already gone. You will also hear a sound similiar to that of playing with a straw in your soft drink at taco bell.
In my experience popping noises have been a symptom of a fried speaker. I never had subs pop, but smaller 6.5" speakers have been toasted and popped here and there with no real sound coming from them.
Usually when you fry a sub it just stops working because it siezes up similar to a piston siezing.
I would just get a cheap speaker of any kind and hook it to the amp. If another speaker works at all, then you can call your current subs cooked.

usually if you have a protection light it means either the amp is fried or you have a loose wire somewhere and it is touching or a bad ground good luck and hope its a easyfix

im starting to think i have a loose wire somewhere because both amps had the same problem and i did a pmcs (lol) on my subs and they are moving freely with no weird noises the ground should be good because its right to the body (seat mount, worked for the past 5 months) i checked the connection at the battery (cleaned it) the only thing i haven't unplugged and put back in is the signal remote wire that turns the amp on

pressing the dust cover is the best way to check the voice coils.
(I once actually MELTED the voice coil on a JL Audio 10w6 which was at the time one of the best subs money could buy -- they replaced the whole thing free of charge)

If it were the subs making the amp go crazy, simply unplugging the subs from the amp and then powering the amp on would show you if that was where the fault was or not. If the lights on the amp still go crazy, then yeah- It's got to be a wiring issue or an issue internally with the amp.
Test your remote wire by just cutting a small piece of wire and connecting the remote and power terminals on your amp (bypass the remote wire from your radio). If everything works fine when bypassing the remote lead from your radio then you know the connection problem lies between the radio and the amp on the remote circuit.
If its still messed up when you have the remote and battery terminals connected and you are sure that your battery and ground wires are good and connected properly, then it's the amp.
Verify these conditions by disconnecting the subs from the amp (at the amp so no wires touch), supply power and ground to the amp, connect the remote and battery terminals on the amp. If the amp powers on as normal, then it's fine and the problem lies elsewhere. If the amp still goes crazy then you will know with out a doubt that the amp is crapped out.

connect the remote and battery terminals on the amp to each other.
(To each other) - not sure if I made that clear. In this test, you are not using the remote lead that runs to the radio.
