Enclosures are finished with gold hardware, gold terminals, and a 1/4″ layer of high density foam with upholstery that is nearly identical to the factory GTR interior. Threaded inserts are built into each enclosure on the sides and rear for using bolts for mounting and attaching accessories as opposed to screws. Internal airspace is further expanded using a calculated area of BlackHole stuffing. Enclosures are designed with a thicker face to recess the subwoofers and prevent baffle flex while incorporating internal corner bracing to reduce air turbulence. The enclosure is built from 5/8″ MDF material for structural rigidity and sound quality. Housing the subwoofers is the highly regarded Gen5 twin 8 curved subwoofer enclosure. The Alpine S-W8D2 subwoofers are a high-performance subwoofer that produces bass that can truly be heard over any aftermarket exhaust. If you want a light setup that performs very well and doesn’t break the bank, this is the setup for you. An advantage of the S-Series subwoofers is that they perform well and are the lightest option available.

The S-series alpine subwoofers leverage many similar technologies as the other more expensive versions such as HAMR surround, dual voice coils, and multi-stacked magnet. This particular system is equipped with Alpine S-W8D2 subwoofers that produce significant bass output at an unbeatable price.


This is a direct plug and play replacement with no wires needing to be cut or holes drilled. This item is for a turn-key system designed for 2009-2014 R35 GT-Rs to upgrade from the factory Bose subwoofers.
