General Installation Notes; Installation Of The Amplifier, Electrical Connection - ESX SX-4120 Bedienungsanleitung

General 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)
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 16-25 mm².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.
