look for a lanzar vibe 1200d. should be at or under 200 and will do rated power. they benched like right at 1200w on 13v and at least 1000w at 12v. solid amp that can take the abuse very well
I know $200 means $200 when you aren't rolling in dough, but I think if you save a few more bucks and bump that to $300 you'll open yourself up to a new world of used amps that are capable of putting the power down with some quality.
