how high are your gains and what are the ohms of the drivers?

check your grounds, a loose or bad ground will caus the amp to cut off at high power demands.

What sub(s) are you hooking up to that 5th channel? Whats the ohms on it/them.

how much amperage does your alternator put out...

if it cuts out while you are moving slow or at a standstill in could very possibly be that the amp is drawing to much power from the alternator and is forced to turn into protect mode (red light usually) and it won't turn back it is shut off. this is a very common problem that happens.

try not too turn it up so high unless you are going 45+ mph, should help

I had a similar problem with my Alpine amp. It turned out there was a bad voice coil in one of my subs.

To each his own, but on my 04 Quad in some poorly lit conditions at night I have enough of a problem seeing to back up that I had to buy 55 watt backup lights. A car looks better to me all around with all windows tinted to match including windshield but the visibility problems aren't worth it to me.

Some people do it. Black out the car, it looks cool.. LOL (I don't do it though)

If nothing is hooked up to your amp, but your head unit RCA's and the power wires (speakers unhooked) and you turn the volume up past half and the amp is going into protect something is either wrong with the amp, or the head unit, or possibly even your head unit is putting out too much voltage in the RCA cables for your amps input circuit to handle, causing protect mode after the voltage reaches the pre-set threshold.
