Amp turning its self down?

Its  kind of hard to tell what the problem in your situation.

This has never happend to me in the past year that i have owned a sound system so i'm not sure what to tell you.

But you should go over your wires and make sure that your power wire is not hot,
or the plastic around is not hot where you can easily bend the wire.

go over your wiring. If everything is good. then do what fuseblower is advising.

Good LuCk!

Yes, you have one of those hard to find problems that could be anything from the very simple (like the decrease in SPL corresponding to the air conditioning coming on) to the not very pretty (like a voice coil gone or partially gone or the amplifier having thermal breakdown problems.)  First make sure there are no parasitic loads on the elctrical system like A/C that might be causing the problem.  Then try by process of elimination.  Are your power and ground wires getting hot?  If so, you need a higher gage.  This is an unlikely source for the problem, but it is possible the amplifier's power is being limited by cable resistance.  Disconnect your cap and see if the problem gets worse or better.  If better, you have a bad cap.  If worse, the cap was not the problem.  Try running only one sub for a while and then the other one and see if it is related to one of the subs.  If the amp was getting hot and then you cooled it, but the problem did not change, then it is most likely not the amplifier shutting down, but it still could be.  Try a different LOC as they are notorious for being shaky.

Having the amp bench tested will at least tell you if it is OK.  Mightrt be worth the expense in any case.

That's a hard question about repairing the tensel.  The tensel lead is probably hitting on the chasis of your sub causing it to go into partial protection causing it to play low.  Once the amp thinks everything is ok your amp returns to normal mode and plays loud again.  You will want to correct the tinsel lead problem because everytime it causes your amp to go into protection mode it weakens the amp.  You can try putting tape on you sub chasis to keep it from shorting if that is what cut the lead.  Other than that you might want to get a new sub or a new set of subs.  Sounds like the amp may be pushing the subs beyond there limit or you can be giving them to high levels of distortion causing them to lose control and bounce too much.

T.Hill I was doing a little research on MA Audio and I am not sure about the power ratings.  I tried to find out a little about the transistors used in the amps but couldn't find anything.  A good way sometimes to determine what your amp can actually do is by looking at the amount of fuses and there ampre ratings.  Your amp may say 1,000 watts but this may not be the case, you might be seeing 800 watts and the distortion level may be a little skewed.  I am thinking this because I remembered a company a while back that was comparable to pyramid.  This is the same company that makes your amplifier, I am not saying that it is not a good amp but I wanted just wanted you to be aware.  Just for anyone that does not know MA Audio is Mobile Authority under a different name.
