hey i kinda need or want some help on making a ported wall for my 4 12's when i bought them they told me they couldnt do a wall in a 4 door cavy. so the built a floor in my trunk. then like 3 days after they closed. but im really wanting to know how to make a wall. i have taking the box out and took my back seat out and set it up and attached a 4x4 to hold it up. but i still feel like there should be more. i want to feel it more if you know what i meen. but dont have 1200 for some one else to make a wall. tired of getting screwd by companies.
