It's about 8mm more
O.0 i have 5.5 inches and 2.09 cf before displacement to work with . I was hoping to put 4 sa-8,s behind the seat of my 06 f350 harley edition . I just became a rep for sundown here in canada and i really want to build something impressive that in a sleeper kind of way the amp will be a saz-2500 . Any suggestions ?
