how do you have the voice coils wired up? you do know that the gain is not a volume control right?

NEVER EVER EVER turn the gains all the way up. You will go through amps like a 5 year old goes through candy.

no amp will ever be worth its price if you don't have a clue on how to use it. the amp can "handle" things just fine, it's just that you are forcing it to shut down by using (well abusing) it

set your gain properly and you won't have a problem

basically things fail when they are pushed beyond their limits. what i suspect could be happening is the sub is wired in parallel and because the sub is only available in a dual 4 ohm VC you're trying to run the amps bridged at 2 ohms which its not rated for. go back to the store and test teh same amp with the voice coils wired in series so you've got an 8ohm load. the amp should be putting out roughly 400 watts and with teh gain set propetly the amp shouldnt go into protect mode. It shouldnt even get overly warm depending on the design, i have no experience with fosgate amps so i'm not sure.

You cannot bridge a RF amp into 2 ohms they can only do 4 ohm mono. You can either rewire the sub or simply run the sub off of one channel in 2 ohms to the sub

you can...but its not stable so it will overheat unless theres a protection circuit that senses the impedence of the speakers its gonna get really hot really fast.

exactly. which is why when he tested both of them they ran really hot until they shut off. I never recommended that he buy that amp and run it at 2 ohms bridged
