Well after a year of fiddling with TA's, X-overs and tweaking the EQ, I decided to rid of my box as well as my "active" setup and went back to stock (except for Head unit). I'm shocked to hear that my stock system which consists of a pair 6 1/2 coaxials up front and a pair of OEM 6x9's in back, sounds just as good IF not better that when I was running active and had 2 Kicker 10" L5's for bass, 6 1/2 front and tweeters in sail panels. I'm thinking that I made it too complex as far as speaker placement and aiming goes. I was never really able to dial-in a satisfying sound. Go figure!
