im going to be undergoing a new box build for my 99 explorer 2door and am looking for anyone thats done something similar. im using 2 dd 9518d1's on 2 m2a's. im looking for an everyday box that will do great with lows. alot of my friends are telling me to do a 6th order wall but me not having any personal experience with them i am a little scared to spend the time/money so im really looking to see if anyone has done such a build and what the musical quality of it was. i would like to meter high but that is not my main objective.
