Thank you for purchasing an Infinity Beta Eight 8" Subwoofer. You�ve selected a premium product that offers superior performance and advanced materials, resulting from over 25 years of loudspeaker design. This Infinity product is made with our ongoing dedication to create the best consumer audio products possible. As a result, you can expect your new Beta Subwoofer to provide you with many years of listening enjoyment. We have included three enclosure types � sealed, vented, and single-reflex bandpass �with three different alignments (i.e., tuning preferences) for each box. Please refer to the discussion in Subwoofer Enclosure Trade-Offs and associated performance graphs (on the inside pages) to select a desired enclosure type and alignment. Each Infinity Beta Eight 8" Subwoofer is covered by our full three-year parts and labor warranty (see back page). Keep your original dated bill of sale in case warranty service is required. IMPORTANT: Installation of automotive stereo components can require extensive experience in dealing with a variety of electrical, and mechanical procedures, including subwoofer box building. Although these instructions explain how to install a Beta Subwoofer in a general sense, they do not show the exact installation methods for your particular vehicle. If you do not have the experience, do not attempt the installation yourself; instead ask your Authorized Infinity Car Audio Dealer about professional installation options.
