I'm having a problem thats driving me crazy, hopefully someone out there can shed some light...

I'm running 2 Diamond Audio 10 inch subs to a Diamond D6 1500 watt class D amp at 2 ohms (so they are only getting 750 watts total). There is a 1 farad capacitor on this amp. I also have a 400 watt Eclipse 4 channel running to eclipse interior speakers. My head unit is an Alpine 9835. All power cables are 4 gauge, including two 4 gauge ground wires coming off of the battery (to compensate for two 4 gauge power wires going to the amps). Both of these amps get hot enough to cook an egg off of. The sub amp even goes into thermal protection, but will come back on after a minute or so of the music being turned down. I can't figure out what is causing this. All the amps are matched to the power requirements of the speakers, and the Diamond amp which is supposed to be insanely stable is only running at half power.

I've been deciding on whether replacing the battery, getting a second battery, or getting a more powerful alternator would help anything, but everyone I talk to tells me something else so the average response is none of those will work.

Any help or insight at all would be greatly appreciated...
