I was looking to run either the nine.4 and the nine.2x or a kicker zx3504 and a zx5502 or possible kx700.5. Is there a difference in the amps? I have run kicker before but they are having a sale on the nine.2x but its not a class d amp? Does that really matter on the subwoofer. I am not looking to upgrade battery, electrical etc etc. The kickers are refurb. from ubid but I got a kicker L7 that was refurb and it was great at 125.00. Possibly going to get a L7 12" and port it.
