Looking to Amp up.

So I have 2 brand RtiA9's and 2 RtiA8's from about 7 years ago plus a 10" Velodyne Sub what Amp should I purchase with $1000 in mind. Also home receiver is a Yamaha Rx-V581. I simply know there is no way an AVR receiver can power these intense speakers but I need big power and quick......party season is right around the corner in Canada here!
