i looked around a little and found 2 amp I think are good buys. the first one is a Rockford Fosgate G160a2 from www.buyloud.com power ratings- 40x2 at 4 ohms and 160x1. The 160x1 figure might be at 2 ohms. i don't think it said. If so it probably puts out about 80 to 100 at 4 ohms bridged. The other is MTX RT2120 from www.crutchfield.com it's rated 30 x2 and 120x1. Both of these amps would produce sufficient power.
