Stereo & Electronics - need a new amp not sure what to get opinions

I have a pioneer amp i got a whole set up for free from a spoild rich kid. But the amp really under powers the subs. does anyone have suggestions for me, the subs are rockford fosgate. 10 inch subs, nothing special, they might handle 150-200 watts rms probably peak in the ball park of 400, i need to find an amp that i can best use these cause im getting maybe 90 watts to each sub right now. and that was after tweaking it. I dont want anything elaborate or with cooling fans and this and that, i dont need all that stuff. Ill probably use the system for about a month, take it out, then when i get bored again put it back in. any suggestions fellas?

Best buy has a deal on a Kenwood 800-wat Bridgeable 2 Channel Amplifier with 3 way power distribution model number KAC-7201

800 watt peak, 460 rms (cont.) x 1 @ 4 ohms
460 w peak, 230 rms (cont.) x 2 @ 2 ohms
300 w peak, 150 rms (cont) x 2 @ 4 ohms.

comes with a fan, cross over frequency range is 50-200 hz, continuous watts per channel (4 ohms) 150, signal to noise ratio 100db, pass through, bass boost selectable o db, 6 db, 12 db

I basically need something that will bump 2 10 inch subs with 150 watts rms capability without over poewring them. Im not looking for the sound system that everyone can hear, just i want to utilize the free subs and box to their best potential.
thanks for the help
