The enclosure is built from 5\/8&#8243; MDF material for structural rigidity and sound quality. Enclosures are designed with a thicker face to recess the subwoofers and prevent baffle flex while incorporating internal corner bracing to reduce air turbulence. Internal airspace is further expanded using a calculated area of BlackHole stuffing. Threaded inserts are built into each enclosure on the sides and rear for using bolts for mounting and attaching accessories as opposed to screws. Enclosures are finished with gold hardware, gold terminals, and a 1\/4&#8243; layer of high density foam with upholstery that is nearly identical to the factory GTR interior. A rear centre console cover and rear deck cover is included to carry the OEM stitching from the front arm rest, through the rear console, and onto the subwoofer enclosure.<\/p>\n<p>Everything you need for the install is included, with the exception of tools. The install time takes approximately two hours depending on your install ability. Tools required for the install are a flat screwdriver, 10mm socket driver, 14mm socket driver, 4mm Allen key.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ngg src=\"galleries\" ids=\"31\" display=\"pro_sidescroll\" captions_enabled=\"0\" captions_display_sharing=\"1\" captions_display_title=\"1\" captions_display_description=\"1\" captions_animation=\"slideup\"]<strong>Highlights:<\/strong><\/p>\n<ul>\n<li>JL Audio 8w3 v3-4 subwoofers + curved enclosure<\/li>\n<li>500 RMS continuous power handling<\/li>\n<li>AudioControl premium line controller and bass control knob<\/li>\n<li>Complete subwoofer upgrade, no amplifier required&nbsp;<\/li>\n<\/ul>\n<p>This item is for a turn-key system designed for<strong> 2015+ R35 GT-Rs<\/strong> to upgrade from the factory Bose subwoofers.
