Subs cutting out!

I just installed my system, its 2 Alpine 300 watt max, with 2 kicker comp c10's 300 watt maxx, both at 150 rms.
My gains are set full
Today i noticed that if i have the volume really loud, one or both the subs cut out for a second, then play on the next bass note, if i turn it down 1 notch it will play fine, could this just be the coonection on the back of the sub to the box that is rattling or something?
Thx
Sam

I'm no pro, and i'm sure someone else can give better information.
But one thing i'd note, is setting your gains all the way up is most likely sending a bad signal (not clean) to your subs which in the long run isn't gonna help the subs life expectancy (and probably not the amps).
As far as the subs cutting out, it could be a bad connection, although it shouldn't be assuming you had your eyes open when doing it all. It wouldn't disconnect enough for one note and then back for the rest of the time. It's more likely due to the fact that you're sending a "clipped" signal to the subs, and for one reason or another they can't handle it.
I'd do a search on this forum for setting gains. Essentially you want your amp to match your head unit is sending (thru the preouts) voltage wise. For realistic setting, use a test tone, and turn the headunit up to about 75% volume, disconnect all other rca's, and slowly turn the gain up until you hear the pitch of the test tone change or just sound different. Then turn it down a tad.
Anything past that point is going to be an unclean signal. There are more hightech and exact ways of doing this (using oscilloscope's - probably spelled wrong) but i'm guessing you don't have one of them laying around.

I think it's probably one of the following:
1) Your amp is overloading and is shutting off to protect itself (turn down gains!)
2) You have an insufficient ground connection. Wire might be too small/too long, hooked up to dirty/painted metal, or not securely connected.
I used to have the same problem. I'm pretty sure it was a bad ground all along...
