7.

 Route 10ga red power wire through grommet into the engine compart-

ment.

8.

 Route 10ga red power wire through engine compartment safely away 

from any moving or hot parts that could damage the wire.

9.

 Cut 10ga red power wire to length, connect the supplied fuse holder 

from the wire kit to the end of the wire.

Optional

- The EBC, or Electronic Bass Control, allows a remote bass 

control to be adjusted from the driver's seat.

Setting Crossover

You should set the crossover to your own personal listening taste. The 

crossover  is  adjustable  to  any  frequency  between  50Hz  (counterclock-
wise) to 150Hz (clockwise). As a guideline, the goal is to create the illu-
sion of bass up front. The higher the crossover point the more “audibly 
visible” your sub is going to be. Take your time and really listen to your 
system, grab a soda and a few of your favorite tunes and have fun.

TROUBLESHOOTING TIPS IF AMP DOES NOT TURN ON

Check all connections at battery and that fuse is installed
Check speaker wire connections
Check ground
Check fuse on pre-amp

18. 

Reinstall threshold trim. Locate and align holes in vehicle with pins on 

trim; secure with the phillips head screws removed earlier.

19. 

Mounting of enclosure: Pass lug holding spare tire into place through 

the hole in enclosure and then through a lug hole (not through the center 
hole) in the spare tire. Replace washer and secure all with wing nut. Zip 
cover.
