best cheap sub configuration

I've been looking at some cheap subs and amps and im trying to figure out what configuration would be the best. I'm looking at the Pioneer TS-W33C subs with either 1 Profile 600Wx1 amp powering just one sub, or the Profile 600Wx2 powering 2 subs. Whatever i'll decide on will go in a sealed inclosure box most likely. Which configuration would give me the best sound quality and overall bass? Can you recommend anything better for around $175-200?
