oh def takin the back seats. is going to be walled off to get as much air space as i can get. thats why im not going with 4 15's cause i dont think there is enough air space for it even in a wall. plus im not one for sticking a bunch a subs in a small area and hoping for the best. subs need to breathe people, it takes air to push air. my only problem is this is going to be my first enclosure build and im building a damn wall. thats like wanting to climb your first mountain and picking mt. everest lol. oh well ill learn as i go i guess. ive read so many damn write ups on building them, and ive watched so many you tube vids on wood working and box building so im pretty confident i can do it.
