amp to stock head unit prob

[bootsy900]

Please help...

i have an Xsite 800 watt, one channel at 4 ohms amp running an Xsite 12" sub. I wired bass blockers into the stock door speakers, and the amp is running off the stock head unit of an '06 Ford F-150. The amp has a built in high/low converter as well that's been wired into the rear door speakers. The problem is that after about 3 inutes of working fine it goes into "protect mode" and stops working. I've checked ground, and even tried running a constant power supply (instead of the remote from the stock head unit). I can't figure why it keeps going into "protect" consistently after about 3 minutes. I've also unplugged the high/low converter just to see if it would run under plain power without actually doing anything, but again, it trips after 3 minutes into "protect." Anybody have any clue? The amp is brand new and never before used. thanks.

Is the gain properly set? what's the sub wired to?

the sub isn't really the issue as it goes into protect even when the speaker wires are removed. it seems to be a problem in th e power supply or something.

how frequently do amps come messed up from the factory? I know xsite isn't exactly the best name on the market.
