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.
• 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 installing the speakers.
• When running speaker wires through sheet metal, be sure to use grommets to properly insulate the
wires from metal edges.
INSTALLATION PROCEDURES
• Since these speakers utilize a unique low profile tweeter housing that has minimal tweeter protrusion,
original factory mounting cutouts can still be used with the factory grills in many cases.
• These PowerBass Autosound speakers can be used above or below the mounting hole. Typically, your
vehicle factory’s speaker cutouts will accommodate these new speakers without any modifications. When
the speaker has been correctly installed, there should be no air leaks between the front and back of the
speaker.
• For door installations, check the clearance of the windows throughout the entire range of the window’s
travel.
• Mount your speakers securely! If the speaker has four or more mounting holes, it is best to use all of
them.
• Check the available mounting depth before installing the speaker. Use care when removing factory
grills, door panels and factory speakers.
