The Outlaw and the RF-7's are an excellent match. I drive my RF-7's with an ATI 1504 (150 x 4 into 8 ohms). The Outlaws based the their own badged amps on that design, at least in the beginning. In fact, ATI may still produce Outlaw's amps - I'm sure a forum member can confirm that one way ot the other. Just for the heck of it, several months ago I bridged the four channels into 2 giving me the potential to drive my RF-7s with over 350 watts per channel - not that I'd ever do something that extreme. But, it is so cool to see all four signal lights on the amp illuminate when I crank up the boys.
