This custom fiberglass subwoofer enclosure will fit under the strut tower bar in the 2003-2008 350Z coupe models and houses 2 X10" subwoofers. It is covered on both sides with black vinyl to match the oem black interior. The photos below are shown with my old subs.

Currently the box has 2 Diamond Audio D10 subs which give a deep bass. One the subs has a shallow dent but both drivers are working fine. Each sub brand new will cost $200.

SOLD!
