[QUOTE="Deiimos, post: 8780233, member: 682903"] That PowerMax 100 amp looks like it would work well, though no experience with that brand. A cheaper option would be using an old server power supply or two. Maybe not this exact one, but something similar which can produce 74 amps at 12v with a line voltage of 120v. You can buy a pair of them and parallel them for over 140 amps, but you need a dedicated circuit breaker as they can pull up to 12a from the mains breaker, each fully loaded. Now a JX1000/1 is typically not going to pull 100a and one 75a power supply would probably suffice and not trip breakers or overload on music, but hard to say until tested. The key is to find one with documented info on wiring it up. The HP DL580 is fairly common and info on it readily available.
