INSTALLING	THE SPEAKERS

1.Use the supplied template to mark the speaker opening and the mounting screw hole locations.

2.Cut out the marked speaker opening in the mounting surface.

NOTE: Steel door panels and the rear deck (behind the upholstery) might already have large cut-out areas for recessing the speaker

3.Drill the four mounting-screw holes.

CAUTION: Be careful not to drill into anything behind the mounting surface.

4.Mount the supplied speed clips directly onto the mounting screw holes that you drilled using the supplied template.

5.If necessary, route new speaker wire from the autosound system to the mounting area.

CAUTIONS: Avoid routing speaker wire where it can be pinched or stepped on. You can usually route it along the channel beneath the vehicle's door facings.

If you selected door locations, you might need to punch a small hole in the door edge (near the door hinges) to route the wires into the door. Leave enough slack wire to open the door all the way.

6.Insert the positive (+) and negative (-) stripped speaker wire ends through the corresponding speaker terminals, wrap them around the terminals, and either solder or crimp them in place.

CAUTIONS: Improper phasing can cause poor bass response. To ensure proper phasing, you need to match your autosound system's positive (+) and negative (-) speaker wires to the corres- ponding positive (+) and negative (-) speaker terminals.

Do not connect any of your speaker terminals to chassis ground.
