Tools and materials you need
• Screwdriver
• Electric drill, 3 mm / 0.12” carbide drill bit
• Mounting screws
• Power wire min. 35 mm² / 2 AWG
• Ground wire min. 35 mm² / 2 AWG
• Speaker wire min. 2 x 4 mm² / 11 AWG
Please note!
• As a precaution it is advisable to disconnect the vehicle’s battery before making
connection to the +12 Volts supply wiring (see owner’s manual of your car for further
information).
• Please use great caution drilling your trunk. Your gas tank and brake lines can be
damaged by puncturing with your drill bit – this could cause damage or failure of your
cars operating systems.
• Never pass wires over sharp angles. It is recommended to buffer the power supply of
the amplifier with an additional battery (GZBP 12.2500 or GZBP 12.3500) to
guarantee a stable operation voltage.
WARNING !
High powered audio systems in a vehicle are capable of generating "Live Concert" levels of sound
pressure. Continued exposure to excessively high volume sound levels may cause hearing loss or
damage. Also, operation of a motor vehicle while listening to audio equipment at high volume
levels may impair your ability to hear external sounds such as; horns, warning signals, or
emergency vehicles, thus constituting to a potential traffic hazard. In the interest of safety,
Consumer Electronics recommends listening at lower volume levels while driving.

Planning your system
Before beginning the installation, consider the following:
a. If you plan to expand your system by adding other components sometime in the
future, ensure adequate space is left, and cooling requirements are met.
b. If your radio is equipped with preamplifier outputs (RCA), it is advisable to use them.
Mounting your amplifier
a. Select a suitable location that is convenient for mounting, is accessible for wiring
and has ample room for air circulation and cooling.
b. Use the amplifier as a template to mark the mounting holes, remove the amplifier and
drill 4 holes. Then mount the amplifier with the mounting screws.
Warning
Chose a mounting position where all eclectic wires are protected from being damaged by sharp edges, heat or
other conditions. +12Volt DC electrical connections must be fused on the battery side. Make sure your radio and
all other devices will be turned off while connection your system.
The GZHA 1.1800DXII does not have an internal fuse. Therefore it is absolutely necessary to
connect the ANL- fuseholder (included in delivery) with its 180 A fuse. The cable length between
amplifier and fuseholder must not be longer than max 20 cm / 7.9”. Please see the connection
diagram on the following side for correct wiring.
