i'm currently looking to replace my stock system with something richer and fuller, i have already purchased a pair of 10" kicker xpl's but don't really know much about them and can't seem to find much info on them. i also have a fosgate punch 400.4 which i plan to run bridged to 200w x 2ch, the xpl's are rated at 350wrms/700wpk each. will this be enough power? i don't want to compete, but be able to bump out a little. also i have been looking at the fosgate punch 300x (37.5w x 4ch) to power the front and rear speakers. will these 2 amps compliment each other properly? and finally can anyone tell me which would be the best choice of 5" x 7"/6" x 8" s, the kicker k57's, the kenwood kfc-6808c's, the pioneer ts-a6867's or offer a good alterative. any info will be greatly appreciated, especially if anyone can tell me more about the xpl's.
