Installation Notes

The amplifier is generally mounted in the rear trunk area but can be mounted in any convenient area such as
beneath a seat. Please be sure to locate this unit where you have reasonable air circulation and protection from
moisture. When considering the mounting location you should minimize the length of the power and speaker leads.
Minimizing both leads will yield a more reliable installation. It is also important to ensure that the heat sink fins are
not against a panel or a surface, preventing air circulation. Do not install the amplifier on a subwoofer box or on
vibrating parts of the vehicle, since the vibrations can cause damage to the amplifiers electrical components.
Installation of the amplifier
Mark the location for the mounting screw holes by using
the amplifier as a template. Drill holes at the marked locations
And firmly fasten the amplifier in place with the mounting screws
supplied in the accessory kit.
Before drilling or cutting any holes, investigate the layout
Of your automobile thoroughly: Take care when working
Near the gas lines or hydraulic lines and electrical wiring.
Electrical Connection
Ground (GND)
This wire is the electrical ground and must be fastened securely to the vehicle chassis. The best
method is to use a threading sheet metal screw since the threads cut into bare metal. Ensure that all paint or other
insulation is remove from around the hole area, and using self tapping screw, securely affix the bare wire ends to the
vehicle chassis. Use as short a piece of cable as possible - use the same gauge as was used for the +12V cable. Make
sure that the connection is safe, a loose connection may result in amplifier noise and fault condition.
Remote (REM)
Many radios or other music sources have an output terminal for connection of the remote turn-on of
the power amplifier. If a radio doesn't have a remote turn-on feature, then you can use the antenna
relay wire, which activates the antenna motor. Please note, if the power antenna retracts when the
radio is operating, then you cannot use the antenna relay wire to operate the remote turn-on.
Batterie Connection (+12V Power)
This wire is usually connected directly to the positive battery terminal. Ensure that the + power supply wire is fused via an
assigned fuse in line with the + power supply wire. Please use a sufficient gauge for the installed amplifiers (min. 10 mm²
for AX 1600D or min 16 mm² for AX 2400D / AX 3200D/ AX 4000D.This connection must be completed using spade lug
with insulating sleeve.
Fuses
The integrated amplifier fuses protect the units from short circuit and overload. The fuse rating is for
4 Ohm loads (impedance) of the speakers, for 2 Ohm loads the fuses may have to get increased by up to 50% in case of
higher power consumption.
