Im finally getting ready to order everything for my system. I just need some final help. I'm leaning more towards getting kickpanels in the front of my truck. (Mid/Tweeter on each side) The back will have a 15" XXX hooked up to a hifonics 1500 amp. I'm not sure whether to get a set of 3 ways in the 2 back doors, or just leave them be? Will the speakers up front be loud enough? I want a balanced system, but I also like it to get loud. Thanks for your help.
