I recently purchased 2 12in JL Subs. One is a 12W3 and the other is a 12W4. I don't know why they were set up like this in an enclosed box, but I got a great deal on them so I figured "why not?" I was hoping someone could reccomend a good Amp for me to power these subs. I'm not too familar with what the "channels" and the "ohms" mean so any help with that would be much appreciated as well. Thanks.
