Hey Tom!
Yes, actually I called Axiom yesterday and talked to Brent. He recommended the 500 for the infamous "hit you in the chest feeling" and that I check the bolts in the subs' driver regarding what I was hearing as port noise. He felt that if tightening the bolts on the driver didn't help, I should call back and speak to someone in the service department... It didn't work, BTW.

I really have wondered about Bass Shakers and such. Maybe in the end, it'll be my only option. Of course then, "in the end" is the only way I'll experience bass.
