Hey everyone im new to the forum. Im helping a friend build a new ported enclosure for 2 L7 15's. As of right now he has 4 15's in the bed of his avalanche in a sealed box. The enormous box takes up the whole bed so he wants to make some room. I came up with a ported box using basic subwoofer calculators. I just want some input before i start building thanks in advance.View attachment 26554651
