Failure to heed the instructions can result in injury or unit damage. CAUTION To prevent injury and damage to the unit, please read and follow the instructions in this manual. We want you to enjoy this system, not get a headache. If you feel unsure about installing this system yourself, have it installed by a qualified Rockford Fosgate technician. Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire adn/or possible injury. The enclosures recommended are designed for great overall performance. Larger boxes tend to be easy to tune to lower frequencies while medium and small boxes are easier to tune to higher frequencies. The vented design is less linear in response than the sealed box but with noticeably more output at the tuning frequency. Higher average output than sealed Tuning frequency can be easily adjusted by changing port length Deep bass response with lower power requirements Great for high output with limited power Continuous exposure to sound pressure levels over 100dB may cause permanent hearing loss. High powered auto sound systems may produce sound pressure levels well over 130dB. Use common sense and practice safe sound. To work properly, the walls of the enclosure must be rigid and not flex when subjected to the high pressures generated by the speaker's operation. for optimum performance , we recommend using 3/4" MDF (Medium Density Fiberboard) and internal bracing. The enclosure should be glued together and secured with nails or screws. These woofers were designed for use primarily in small ported enclosures. By utilizing the latest materials and construction techniques, we are able to offer a speaker with high output at low frequencies while requiring a minimum of operating space. Calculating volume is merely a matter of measuring the dimensions in inches and using the formula: H x W x D divided by 1728 (cubic feet). [. . . ] the removable impedance selection jumper also provides fused protection in severe overload conditions and should only be replaced by an authorized dealer. As per the illustration, by inverting the center plug the dual voice coil's are connected in either a "series of parallel" configuration allowing for convenient configuration for optimal amplifier loading. Please make sure that this center plug is securely fitted. [. . . ]
