Important safety instructions This symbol alerts the user to the presence of important instructions. Failure to heed these instructions can result in injury or damage to the speakers.

Setting up the car audio subwoofer Setting up the car audio subwoofer The following are basic installation instructions. If you feel unsure about personally installing this speaker system, Dynex recommends using the services of a professional car audio installation center. Before installation, follow these guidelines: 1 Carefully read and understand the instructions before installing this product. 2 Disconnect the negative terminal from the battery before installing this product. 3 If additional wiring is needed, we recommend running all wires prior to mounting your speaker in place. 4 Use the highest quality connectors for a reliable installation and to minimize signal or power loss. 5 Use caution before you drill or cut. Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. 6 Never run speaker wires underneath your vehicle. Running speaker wires inside the vehicle provides the best protection from exhaust heat and environmental elements. 7 Avoid running wires over, near, or through sharp edged surfaces. Use rubber grommets to protect any wires routed through metal, especially the firewall. Installing the subwoofer To achieve the best possible sound from this subwoofer enclosure, Dynex recommends acquiring the services of a professional car audio installation center. If you feel confident in your ability to install this product without professional assistance, here are some placement recommendations and installation tips to assist you. This is a guide; you may find other placements provide better results. • All moving parts and factory electrical wires should be out of the way so they don’t interfere after installation. • Ensure the wire is of sufficient length to avoid pulling or stretching, especially if the wire will be run under or through the factory interior. • Use electrical tape and wire ties to properly secure all wires. • Avoid installing speakers or electronics where they can be subject to moisture. • Ensure the speaker wires are connected using correct polarity. The positive polarity is marked by a (+) sign. Incorrectly connected subwoofer will result in limited bass output. • Speaker wire should be isolated from the vehicle’s electrical system to avoid noise being picked up by the amplifiers. • Use 14 gauge or larger sized speaker wire to ensure your subwoofer receives the full power output of your amplifier. • Remember to listen responsibly and respect your ears. Being exposed to sounds over 125dB for even short periods of time can create permanent hearing loss. 4 Setting up the car audio subwoofer 4 Setting up the car audio subwoofer To work properly, the walls of your enclosure must be free from flexing during high sound pressure generated by your subwoofer(s). For best performance, always use MDF (Medium Density Fiberboard) to build your enclosure. We highly recommend that your wood be at least ." in thickness. The enclosure should be sealed internally with silicon or glue and secured with screws every 4". Assemble the box before cutting the subwoofer hole(s). If the box will be mounted in a vehicle, fasten it securely with metal "L" shaped brackets. To build an enclosure, calculations will need to be made using the information found on the following 3 pages. Remember: •Use ." MDF • Use silicon or glue in joints • Use screws every 4 inches We at Dynex are diligent in checking the dimensions provided. The engineers, staff and installers provide this information to make your installation go as smoothly as possible. Errors do occasionally occur. We highly recommend that you personally measure your subwoofer prior to installation to avoid any damage.
