Here's the mono Profile California AP700 amp, it's rated to put out 220 rms @ 4ohms. I wasn't to kean on this brand but decided to give it a try anyway, considering it's only $119 and has great ratings on Crutchfield. It's feels very solid, so far I'm not disappointed with my choice. The CDT EF-80 sub is rated for 200 rms (great price, $59 at woofersetc.com).
Overall, the bass sounds great, nice and clean.
