When I measured it The Dimensions where 36 Wide by 18 High by 20 Deep with the back seats up If I did the math right that would come out to about 7.5 cuft (let me know if im wrong on this) will 4 tens fit in that area and I didnt even bother to look at the sizes the Q comes in... the smallest being 12 and I want to run 10's so it's between the SSA Icon, RE SX or the Fi BL Now if i run the Sundown saz 3000d what type of electrical upgrades would I have to do
