SPEAKERS NOT INCLUDED. Built for FOUR 6.5 inch subs (which is MORE area than two 8 inch subs and MUCH more than a single 10 inch sub). Built to fire DOWN directly behind the passengers on the leading edge of the parcel shelf because this method gives the best response in the miata.
Clears the soft top, clears four point rollbars such as the Autopower and M2 Sport. Note that what looks like a port in the middle is NOT a port...this is a sealed box and that item is the middle is called a "punch" and it is actually a strength tube through the center for yet more strength and rigidity.
Includes brackets to bolts to where the factory 94-97 brace is located behind the seat.
