that amp is atleast 2x the size of the rockford.The JL XD600/1 makes twice the power (and then some) but is only marginally larger at 8-1/2"W x 2"H x 7-3/8"D.I am sure the little RF will do rated plus alittle more too. Watched a video on Youtube from CES and got a great breakdown on the technology used in these little amps. Some really innovative stuff coming out right now from JL, RF, JBL, PPI and Kicker.
