here is my setup: i have one set of audiobahn component speakers in the front doors, a pair of infinity kappa speakers in the rear deck and an elemental designs 15kd4 (might get a 15kd2 instead, not sure yet) for my sub. i have been looking around at different places and found two sets of amps that i like and that i think would work. it is either between the rockford fosgate punch 400s (powering the sub) and the 300x (powering the 4 speakers) OR the Visonik V2508 (powering the sub) and the V4208 (powering the 4 speakers). which would work the best and give me the best sound? do you prefer rockford or visonik? which one will last the longest? best quaility sound?
