I have my dual 2 ohm CVR on a zx750.1 (2 ohm stable) at 1 ohm... has never gotten warm and does rated power. Talk to polecat, he'll give you info about any line of kicker amp.
I've always liked the looks of this amp for moderate 1 ohm power...http://www.hifisoundconnection.com/Shop/Control/Product/fp/vpid/2666859/vpcsid/0/SFV/30046/order/asc/order_by/sell_price
