So, i got two Sa-8s. Made a sealed box and all. It came out to be .7^3ft before sub displacement. I looked online and read the subs were .8 of displacement. Well, i put that in as .08 not .8. So i think my box is too small. I dont wanna rebuild it cause it was hard to build but it seems like i gotta. So, i need help designing a box. Its going under the seat of a 2011 F150. Id love ported but i cant design that. All help would be greatly appreciated.
