Sir
Get a Kenwood KAC 7202 or Sony GTR2002 for 9K, and Kenwood KAC5202 for speakers, 3.5K Rs.
Or Alternatively Mono Kenwood M615D, 300W @ 2 ohm for 9K, or Mono 8101D 500W@ 1 ohm for 10.5K.
The Kenwood 7202 and GTR2002 are tri way, means you can power your SUB and 2 speakers, if you can find the external triway adapter/passive crossover.
Regards
