I need some help, I know there may be some better options but best buy has alpine subs buy one get one free so that the plan. I have a kicker 750.1 amp and am trying to decide which sub to go with Alpine type r 12 1800w peak 600rms OR Alpine type e 12 750w peak 250 rms? I have a box for 2 12's in my truck now that I built for my old set up and would like to keep using it. I could also chop the box and just go with 1 sub and put the other in something else. Let me hear your thoughts. Thanks
