I have this left over. Its pretty much the back half of a sub box enclosure for the passenger side in the g35. This would be perfect for the person looking to do it themselves and not getting that fiberglass smell in the car. Can be made to fit a 12 or 10. here are some pictures of it and how it can look when done. this is for the sedan. Only $40bucks and I'll even throw in some extra fiberglass mat. Shipping will be 15 bucks for the u.s.

 

interested, whats your location?
