Each Infinity Beta Twelve.dvc 12" Dual Voice-Coil Subwoofer is covered by our limited parts and labor warranty (see the enclosed warranty card).

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.
