I have a pair of pioneer 10's just like those and love them, im giving them less then half the rms and they still pound. definetly gotta reccomend them, but the shipping charges are rediculous.
You can get good bass for cheap. You can go to crutchfield and get 2 infinity 10's for 90.00 shipped.Then just get a small 2 channel for like 110-125 and for about 200 you can sound 10x better. Thats what i would do...
