[QUOTE="F150Matt, post: 93572, member: 543857"] Well I built a ported box for my L7's. First of all I never had it metered with them in the sealed box except in an outlaw competition and it did a 150.0 with the mic behind the seat. Well yesterday I took my ported box at 1.75ft^3 per woofer with the subs in their own separate chambers to a shop and got it metered. On the dash it did a 138.8, in the port it was around 155-156db's. I know there are people getting much higher numbers out of the L7's. I'm limited on room in my single cab truck and I can't get my parents to let me cut the bed. I cant get a bigger box, the only option I see is maybe more power, but thats not gonna increase my score very much. What can I do? What am I doing wrong? 138.8 was very dissapointing. My friend has an extra cab toyota with 3 pioneer IMPP 12's in a sealed box and does a 148-149 consistently. I should be hitting higher, what did I do wrong? [/QUOTE]
