another notable would be the Crescendo 2200, it would give you what you need at 2ohms for $380....again, I have not heard this one either, but it is recommended because it does rated.

any recommendations for other woofers that are under 5.75" mounting depth?
Back in the day I rolled with all the RF gear, but many seem to think that only the Power Line of amps is good. I wouldn't know but they sure are expensive. I have heard a few P3's over the last weekend and they sounded mediocre at best. Are the new Sundown amps released yet? SSA is all out of stock.
