I need some details on both of these amps, they are made by the same manufacturer I believe. The REF seems like it would be better on SQ and has a much better crossover. The P900.4 on the other hand is class D so it's much more efficient, but doesn't have a great crossover so I don't think I'll be able to run active (which I want to) with it. I will be driving a JBL C608GTI MKII comp set.
My question is which one would be better for this? Should I get the REF and just run active or get the P900.4 and run passive until I can get an active processor?
