PREPARING FOR INSTALLATION
NOTE: The tools listed below may be required for basic installation.
• An electric drill with bits
• Saber, circular and jig saw
• Phillips-head and standard screwdrivers
• Wire strippers
• Crimping tool and needle-nose pliers
• Silicone sealant (for enclosures), closed cell weather-stripping (for the speakers)
INSTALLATION PRECAUTIONS
NOTE: Proceed only if you are a qualified installer otherwise; let your dealer do it.
• Always wear protective eyewear when using tools.
• Turn off all stereo and other electrical devices before you begin.
• Disconnect the (-) negative lead from your vehicle’s battery.
• Keep the speakers in the package until final installation, and always rest it with the cone facing up.
Never use force when installing a speaker.
• Locate all fuel lines, brake lines, oil lines, and electrical cables when planning your installation.
• Check to see if there is enough clearance behind the mounting surface before drilling holes or install-
ing screws for proper speaker ventilation.
• Also make sure there’s enough front clearance for speaker cone excursion. Failure to do this could
cause the cone to vibrate against any obstructing object.
• Use a utility knife to trim away fabric from the speaker mounting hole location before drilling. It is
hard to get a good seal if you have both the carpet & subwoofer gasket between the speaker and
the enclosure.
• When running speaker wires through sheet metal, be sure to use grommets to properly insulate the
wires from metal edges.
