thanks for the reply...i built the ones i have now but they are seperate and only measure .4cf ..i have tried to make one that held both subs but it didnt sound as good as my small ones..my brother has a pro box with 2 mtx 10'' subs in his chevy that i put in my truck and it blows mine away..it sounds louder and "deeper"..its made of hard plastic with like rino liner on it or something...we tried to make one like it from 3/4 mdf that fit under my seat but it didnt sound near as good as his or even the ones i have now so i scraped it..i did find the pro box made for 09-up f150 but its a single 10'' or 2- 8''s ...they are pricey tho...
