which model are u getting, the dvc 2ohn or dvc 4ohm models?
if u get the dvc 2ohm and wire the 4 subs in series/parallel u will get 1ohm load.
if u get the dvc 4ohm and wire the 4 subs in series/parellel u will get 2ohm load
however these subs are 750W rms nominal power each, thats your minimum requirement, max power is 1500W, so if u can get 1000W per sub is better, that means u will need 4000W from the amp at 1 ohm or 2 ohm depending on your sub model. i guess better to buy 4 amps la....1000W per amp shouldnt be a problem with the brands u mentioned above.
u can buy from any audio shop that are kicker dealers, they would also be selling mohawk as well. prokick and stellar is different distributor so i guess up to the shop if they are dealers or not. u can also order from some zth members here they have mohawk lubang also...
