1. Mark two holes on the side of each Speaker box to drill the mounting holes. (Holes are not predrilled because there are many different ways that each speaker box can be mounted). (See figure 1).

3. Place each speaker box in the mounting position and mark the vehicle directly under the (2) 3/8” mounting holes drilled in the speaker box.

WARNING! Make sure that there is nothing under the vehicle that will be damaged by the drill bit when drilling.

6. Fasten each speaker box with (2) 5/16 x 1 ¼” bolts, (2) 5/16” nylock nuts, and (8) 5/16” washers. If you are mounting the speaker on its side you will need to use (4) of the washers for spacers. (See figure 2).

7. Place speaker cloth between speaker and grill then bolt speaker to grill.

8. Connect speaker wires to speaker. (Consult speaker installation manual for correct wire connections.)

9. Bolt the grill to the Speaker box using the ¼-20 x ½ screws and ¼” washers.
