CAUTION
!!
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.
