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. 10-16 mm² for MXB-280/MXB-
2125/MXB-2200/MXB-480 or min 16-25 mm² for MXB-2250/MXB-4125/MXB-4175).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.
