I have 2 of the above going in a sealed box. I was considering either the Kicker 600.1 or the JL 500/1. Any pros or cons to either of these? Also how about the wiring setup for the speakers? It's been awhile since I have done this so I thought I would ask here first.
I'd do the JL, I like the SQ of the amps better. with dual 4, wire the coils in series, then the subs parallel to the amp. that'll create a 4 ohm load and is your only option. That is another reason to go with the JL.
