Ok. I ran (4) pa subs with a x-max close to your car audio subs specs. Mine were 18" and 240oz magnets, but still "comparable". Look for a pro audio amp that has low pass and hi pass filters. I ran crown cdi 1000 amps. There's a comparable model for less cash. Mine, i could hook up a laptop and do anything i wanted to it. Super underrated units. Oh, by the way.... it was..... steller.
