I have an Orion XTRpro1000 that'll power your sub perfectly. Great old-school amp that is rated 1000w RMS @ 1 ohm, but probably more like 1200w @ 14.4v. I bought it for $275 off ebay as a refurbished item and never powered it up (changed my mind on setups). It includes a 6-month warranty, and I'm only asking $235 including shipping for it. Let me know if you're interested.
