Best amp to power to Infinity Perfects?

I have one Infinity Perfect 12 (single voice coil) rated at 350w rms, and I want to get another one to run a pair of them. They will be in a dual chamber sealed box with about 1.25 cubic feet of space each. I would like to run each of them at 350-400 watts into a 2 ohm load (subs wired in parallel). What would be good amp to match up well with this setup? I'm assuming I need a mono amp that pushes at least 750 watts rms, so that when I split it between the two subs it will half the power to each..is this correct? Thanks....

Try an Orion 6002 amplifier. It runs true 600 x 1(mono) watt RMS, and would be more than enough to power the Perfects.

And yes,if you wire them in parallel, they will run at a 2 ohm load.

I'd use a Phoenix Gold X600.1 That's 300 to each, which with that much airspace for each sub, will push both to full excursion. Damn good subs.

If you want to run a full 300 - 400 watts a sub, that box design is too big. I put my pair in an *identically* sized enclosure and ran a JL 500/1 to it.

Really nasty and boomy... anything lower than like 40 - 50 hz would overextend the things licketly split.

On the other hand, I wired the same setup to 8-ohms.. about 125watts/woofer... and they did real well. Not nearly as loud, but they could handle the power much better and sounded great playing a range of music.

Still... truth be told I'm an 'aggressive user' and I really like rap music.. so.. I wired the same pair back to 4-ohms in a *much* smaller box.. about 1.9cft net, and they sounded as good playing jazz and classical and all that soft stuff.. but switching over to ODB was just as satisfying. Tight, loud bass.

From the Sounddomain.com description:
The Perfect is designed to deliver kick-butt bass in small sealed enclosures.
I would normally never use a quote like this to make a point, but I'm really serious when I tell you, they aren't kidding.
*small* sealed.

I had mine in a 1 cubic foot gross box. Powered it with 400 watts, and never had a problem with overexcursion, unless I just pushed the amp into clipping.

Yea that seemed to be the cut-off for great-sound/overextention... I built a half-dozen boxes for my pair before they were stolen and anything much larger than 1/ft/sub really didn't do well with the amp wired to 2-ohms..

I've heard of ppl having poor results in ported enclosures as well. Don't know anything about that though, didn't ever try one, didn't have the space.
