Sir get the VTREK PS2000 for SUB and Kenwood 5204 for 2 6 X 9.
Kenwood - KAC-5204
Will get the job done and cost you around 11K for both AMPS minus what you get for your AudioBank.
or You can get a single Sony GTR 2002 and run it for SUB and speakers, provided you can keep it cool, the output will be slightly less but sound will be better.
