[QUOTE="nVRuckus, post: 2160636, member: 561806"] He is running a 18" BTL before someone asks. an IA 20.1 amp and currently his trunk it sealed off from the cab with a piece of factory metal behind the seat with MDF and 2 amps mounted to that metal. I say he need to cut that steal out to gain dB into the cab but someone told him it wont make that much of a difference. currently only air going from trunk to cab is the 2 6x 9 holes in the rear deck. Also he is tuned to like about 32Hz he says currently which i think needs to be changed. What range should we look for tuning for SPL on a BTL? 40-45hz tuning? [/QUOTE]
