for purchasing an Infinity Kappa Perfect subwoofer. Kappa Perfect subwoofers are engineered for extreme power handling in both sealed and vented boxes and constructed using state-of-the-art materials for unequaled performance and longevity. To ensure maximum subwoofer performance, we strongly recommend that installation be left to a qualified professional. Although these instructions and the enclosed data sheet explain how to install a Kappa Perfect subwoofer in a general sense, they do not show box construction details and exact installation methods for your particular vehicle.
