head to cab conection?!

hi guys,
i recently blew up an Ampeg SVT-7 pro head and really do not want to do the same to my new Hartke Kilo!!!
the Hartke Kilo has a bridged output sending 1000 watts at 4ohm
my cab is a ABM 810 which is rated at 1200 watts at 4ohms so as far as i am aware this is a compatible match.
what im wanting to know is do i need a 2 or 4 pin speakon cable to connect these two together, i can not find wiring diagrams anywhere

is anybody familiar with these models?
