I have this hooked up to a planet audio P9692B head unit with a pair of 6×9 coaxial front doors and 6.5. 3way coaxial rear doors cerwin vegas in my 07 XTERRA. Instead of adding a pair of full range speakers to the 2ch amp I ran a splitter off the sub out and added a 8″ 600 watt 4ohm svc sub driver to one of the channels, with the sub remote volume connected. I love my vegas, powered by planet audio. This is the second time I’ve had planet audio powering my vegas. Great match up, old school and new school.
