I have the PDR 4 channel and it is working great for me. I also have that same sub along with a 500w at 2ohm alpine mono block waiting for a spring install. will be getting one of the ******** enclosures to go with it. the Sub I have had previously and it is a very good performer for me in the past though in previous application I had it underpowered a bit. this time I have it matched up better, can't wait to hear the lows out of it
