You have purchased the finest automotive subwoofer the industry has to offer. Installed correctly, the ProSeries subwoofers will offer unprecedented performance for many years to come.
Enclosure Recommendations The ProSeries and Competitor Series subwoofers are designed to deliver optimum performance in small sealed enclosures. The Generator Series subwoofers are designed for either sealed or ported enclosures. The following are the recommended enclosure volumes: ProSeries Competitor Series Sealed Enclosures 12.5LF 10.5LF 8.5LF Gross Internal Volume 1.0ft3 Generator Series 1500 1200 1000 800 GS1500 GS1200 GS1000 0.5ft3 0.3ft3 1.5ft3 1.0ft3 0.5ft3 0.3ft3 2.5ft3 1.5ft3 .
Calculating your enclosure volume: Internal dimensions Height (inches) x Width (inches) x Depth (inches) = Gross Internal Volume (cubic inches) Gross Internal Volume (cubic inches) 1728 = Gross Internal Volume (cubic feet) or: Height (cm) x Width (cm) x Depth (cm) 1000 = Gross Internal Volume (liters) Conversion Formulas 1" = 2.54cm 1ft3 = 28.32 liters 1ft3 = 1,728in3 W Remember to account for material thickness when determining external dimensions.
Building an Enclosure Use at least 3⁄4-inch MDF to build the enclosure (1-inch is preferable). The joints should be liberally glued with carpenter’s wood glue and screwed together with wood screws and sealed internally with a bead of silicone rubber or hot melt glue. Drill pilot holes to prevent the wood from splitting and tighten the screws as much as possible. Excess glue can be wiped off with a damp sponge or paper towel. Warning It is extremely important to completely seal the enclosure.
Locating Subwoofer Enclosure in Vehicle The placement of the enclosure is one of the most important factors concerning installation. As each vehicle’s interior acoustics are different, experimentation is the key to optimizing performance. Hatchbacks/Sport Utility Vehicles Locate the enclosure in a rear corner for maximum output. Experiment with the subwoofer’s placement.
Sedans Provide as clear a path as possible into the cabin by venting through a folded-down arm rest, venting through the rear deck, or venting through an unused speaker opening in the rear deck. Keep any restrictive materials such as wood, hard plastic or metal from directly blocking the subwoofer.
