level before distortion.
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-

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.
