JL Audio 8W3v3-4 8" Subwoofer - 4Ω

If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.

The 8W3v3-4 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

Safety Notice
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.
