Are the buttkickers going to sound good though? It sounds like they are designed for the 'shakers'.
People have been using them to drive subs even though it was made for shakers.
A recent review of three amps;
Crown XLS 402b
Behringer EP2500
Buttkicker BKA1000

The majority of amps don't even meet their power spec @ 20hz, low distortion,
even proamps suffer pretty bad. The reason you want a 2kw amp is to get a true 1kw operation.
Most people buying amps to drive subs are mislead about the true power vs. published specs.
