okay well Ivv had a few post/questions about what type of setup I should go with in my truck and probley the cost. My freind has 3 kicker 15in 17's hooked up to 2 zx2500 amps. Now my question is would it be better to go with 4 kicker l7's 15in subs hooked up to 2 rockford forsgate amps. Or 2 fi btl 18in subs each with there own rockford forsgate amps.........should these systems be in ported or sealed boxes im looking for loud,just bumpin system. now how much would it be to get a coustom box made with these subs and amps and instaulled into my truck because I dont wanna mess with it because its brand new
