I finally had the time to get my sub hooked up. It's a svs 12.1 driver (purchased on here) in a 48" x 16" sonotube. I have it hooked to an outlaw m200 amp (325w @ 4ohm). It sounds great. Not boomy and pulls much lower then my PSW 303. However, I was expecting it to have more volume (louder). Not sure if it's not enough power but SVS told me to use 300wpc. Any suggestions?
