Setting Bass Boost
1. Turn the gain and bass control all the way
down (counterclockwise).
2. Turn the vehicle on, and make sure the source
unit is turned on.
3. Insert a CD/DVD with undistorted music.
4. Start to increase the volume at the source unit
until you hear distortion (about 90%).
5. Turn the volume down at the source unit until
the distortion goes away.
6. At the amplifi er, slowly turn the Bass Boost
control up (clockwise) until you hear a slight
distortion from the speakers.
7. Turn the Bass Boost control back down until
the distortion goes away.
8. When the Bass Boost control is properly set,
you should be able to achieve the maximum
undistorted output with the volume turned all
the way up.
Warning!
Do not set or increase the amplifi er’s gain when setting
the Bass Boost control. Increasing the gain even slightly
will cause the amplifi er to heat up and amplifi er failure
could occur.

Wiring
• Before you begin routing and connecting the
power wires, disconnect the negative ground
cable from the vehicle’s battery.
• Install and connect the highest possible wire
gauge the amplifi er’s terminal will accept (1/0
GAUGE) for both power cables (+12V and GND).
• Install an in-line fuse into the positive (+) wire 18
inches away from the car battery. It should be
the same rating as the amplifi er’s internal fuse(s)
• Route all power and speaker wires inside the
vehicle toward the amplifi er prior to mounting it.
• Avoid routing electrical wires where they are at
risk of getting pinched.
• Use rubber or plastic grommets to protect any
wires when routing through metal.
• Route the power cables through one side of
the vehicle while routing the RCA audio cables
through the other side.
• The ground connections should be as short as
possible and always be connected to chassis
metal. Chassis ground connection should be
clean, rust free, unpainted and as close to the
amplifi er as possible.
WARNING!
• Disconnect the negative (-) battery terminal
before routing cables and wires to prevent
electrical shorts.
• Never route wires underneath the vehicle.
• Do not run wires through sharp edges.
• Always turn off amplifi er(s) before making any
type of connection.
