Great price on that US Acoustics, man. Here's a couple others I found:

Boston Acoustics US)

Boston GT-4100. Get these amazing amps while Boston is still selling them. 100W per channel of A/B goodness. Don't worry that they put out less than your speaker's rating, either.

JL Audio XD400 4 4 Channel Car Amplifier Amp 01 B40801A 699440982610 | eBay

Phoenix Gold R8 0 4 4 Channel Amp Amplifier 800 Watts | eBay

I have the 5.0:4. Very well-powered amp and quite a stunner for its price

On the new side of the fence:

Precision Power PPI BK 800.4 800W RMS, 4-Ch Class A/B Black Ice Car Amp

Precision Power PPI P900.4 (p9004) 4-Channel Phantom Car Amplifier

 
I am actually looking at this amp, not sure if its too much power for you but price is around $135 and i am still looking for some reviews

Hifonics Zeus ZRX1000.4 4-Channel Class A/B Zeus Series Car Amplifier $135

RMS Power Output: 125 Watts x 4 Channels @ 4 ohms

RMS Power Output: 250 Watts x 4 Channels @ 2 ohms

Bridged RMS Power Output: 500 Watts x 2 Channels @ 4 ohms

fuse 30ax2

I wouldn't consider than amp worthy of carrying the full-range class d title it claims. Maxxsonix-owned Hifonics tends to be a bit on the underrated side of things, so realistically, it does 100x4, not 125x4

i am actually more for the 2ohm rating of 250w x4, dont you think this will produce close to that?

Close? Probably. I'd just assume 200@2. Why not lift the budget a bit and get something that actually does rated, like a MB quart DSC4125 (used) or PPI P900.4?

 
I just opened a thread on PPI 900.4 VS HIFONICS ZRX2000.4 both closely priced but hifonics looks beefier
Not a chance, man. The PPI is smaller, cleaner, has a higher noise floor, adapters to fit 0ga wire, and actually gets praise from folks on DIYMA (which, at this price range, is no small feat).

 
the boston acoustics listed above is the best amp easly for price 1 ohm stable and at 224

the links to bostons website doesent work but if you call them or hit refurbished products on the uper left then go to page 4 you will see the gt-4100

they also have a 5 channel gta-1105 which is really nice for 150 shipped and it would work perfectly with your speakers plus if you wanted to put a 400-500rms sub it would sound amazing later on
