Alright it's getting real old, and expensive! At first I thought it was probably my amp but bought another amp and I am having the same problem! The power to the amp is staying on but My sub just stops hitting,and it cuts in and out, It will work for as long as I'm driving I will park my car, and when I turn it back on every thing will be working just fine and, then a couple minutes later, amp cuts out and won't hit for a couple hours or a couple days.... I have checked the sub multiple times and I don't see it being the sub or the amp... I have never had this problem before, and I had been running the same sub and amp for a year and a half, and never had a problem till now(and now I have tried 4 different amps and still the same thing happens).... so my guesses are it's grounding somewhere, short in some of the wiring, might just need a new battery...Idk could use some help on this one! Thanks

Re: Amp staying on but cutting out?
Actually you answered your own question in your paragraph. I draw your attention to your statement of: "It will work for as long as I'm driving I will park my car, and when I
turn it back on every thing will be working just fine and, then a
couple minutes later, amp cuts out and won't hit for a couple hours or
a couple days.... I have checked the sub multiple times and I don't see
it being the sub or the amp"
You are correct it is neither the Sub nor the Amp. The problem is either your voltage regulator or your alternator. one and or the other is going bad.
Here is some advice check your ground wires, the buy a dual alternator kit, it contains the parts you will need to add an additional alternator to your car. This will provide the power you need.

Something is def. wrong. did you check the fuses on the amp after the light went out? probly have a bad connection somewhere. check ground wire and power make sure they have a good connection and arent cut up and shorting out.
probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.
Did some research and it sounds like a wicked lil amp with clean clean sound-its hard to say what subs to tell you to run because everyone has different taste- and without knowing what your setup is going to be theres no real way to actually say-the amp is made to run 3 channels -so focusing on the sub channel only i personally say get a pair of 10s or a good 12-your not throwing a ton of power so you dont have to go balls out on the subs- i personally like MTX subs and xtant is made by MTX so that wouldnt be far from home -good luck with that
disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro
The reason it used to cut-off at 60% volume as you said before, Is probably due to the "protection circuit mode" being tripped.
You can try resetting it by turning off your CD player ,removing the Batt( + ) and Gnd ( - ) terminals from the amp for a short period. Reconnect them Allow the amp to receive power but not switch on (keep cd player/remote power source off)
If you dont know how to wire the CD player to control the amps power status , the easiest way is to connect the 'power antenna' or similar low voltage throughput wire from the head-unit to the amp's Remote terminal.
My old amp did the same thing ,and would need to be powered off/on before resuming sound output, sometimes I had lots of trouble with the protect mode staying on , even with little or no sound output from headunit.
If the voltage is dropping to 8v, it sounds like there is a problem with either the B+ line or the ground connection. You should also check the voltage across the battery terminals to see if the voltage is dropping at the source.
The amp may be going into protect mode. Disconnect all speaker wires from the amplifier's terminals. Also disconnect the RCA cables from the amp. Does it still go into protect?
Insert a 20 amp fuse in the B+ line and try to power it up. If the fuse blows with no speakers connected to it, the amp probably has a blown channel.
