You have maxed out the amp! if your running one 4ga. pwr wire to all your amps, it's choking. Going to Wendy's buying a frosty and sucking it thru a straw!. Your amp is starving for more Voltage and current. That amps peak output is 1200w @ 1ohm, not too shabby! Now onto the next issue: Grounding!, just as important as power! Your amp MUST be grounded properly. Don't ground it to a seatbolt or side wall of the vehicle, go directly to the floor, hopefully less than 2-3ft tops. using the same gauge wire as power. If your power is longer than 12 feet, and in most cars it is, you loose alot of voltage and current flow to the amp the longer the run, the more you loose. That's just how DC power works. What's happening to your amp is it's working itself to death and creating massive amounts of heat. "enough to cook dinner" Run a 2ga or 1ot power wire to a distribution block at the amps. Wire in your other amps, then use the stiffening cap just for the sub amp. Not a cheap answer but it will solve most of your problem. Next, set the gain on the Sub amp NO HIGHER than 1 o'clock. Beyond this, and there's no help for it, there's no more gas pedal to push!. Enjoy your system but don't kill it! Hope this helps
