Are the subs ported or sealed, if sealed, how big are both boxes. looks a little to big for sealed 12's. also since you got everything for **** near free, you should invest in a decent sub box. From looking at the video, and from my experience, i would say that the subs are two close to the top of the trunk as u always should leave enough room to let the bass roll of properly, or you'll have double bass or cancellations.. and i notice you have a jvc deck, what model? and how do u like it? i have the KD-AHD59 and i love mine
