PLEASE READ BEFORE INSTALLATION
Thank you for selecting a Ground Zero amplifier.
We are providing a helpful hints list which should keep you from experiencing
unnecessary shut down.
Have fun with this high quality Hydrogen product.
Hydrogen amplifier
Due to their state- of- the- art technology and high efficiency, these Class-D mono amplifiers help your system to provide an impressive sound experience. The digital circuit technology of the power supply and the si gnal processing allows achieving maximum performance levels from the provided power. Due to the different filters and circuits a very high power output is achieved, therefore these amplifiers are made for low frequency information (Subwoofer). They can not be used for high- and midrange speakers.
The link mode enables to use to full power of two amplifiers for one speaker. This is first of all advantageous for a really powerful and lively music playback.

Tools and materials you need
Screwdriver
Electric drill, 3 mm / 0.12” carbide drill bit
Mounting screws

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 damage d 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.

With this controller you can adjust the input sensitivity.
6 Bass boost controlle
r
For adjusting of the bass boost level in the range from 0 to +9 dB.
7 Bass frequency controller
For adjusting of the bass boost frequency in a range from 30Hz to 80Hz.
8 Subsonic controller
This controller allows you to filter low frequencies in a range between 5 and 50 Hz. This function reduces the mechanical Xm ax and raises the capacity of the connected subwoofer.
9 Cinch Outputs For connection of additional amplifiers.
10 Low pass controller
A
djust the variable lowpass frequency to the desired frequency
between 30 and 250 Hz using the controller.
11 Phase shift controller
This controller allows you to fit the subwoofer channel in-phase to the front system.
12 Remote control input For connection of the bass remote control. 13 Slave In connection For connection of the slave amplifier in link mode. See page 10 14 Master Out connection For connection of the master amplifier in link mode. See page 10
15 Master / Slave Switch
For choosing the operation mode of each amplifier in link mode. See page 10
16 Capacitor connection For connection of a optional powercap.
Turning on the amplifier
The amplifier automatically turns on a few seconds afte r you turn on your radio. Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools (At about 80° / 176° F).
Adjusting the audio level
1. LEVEL (Min/Max): Turn fully counter- clockwise to MIN position
2. Turn the auto sound system's volume control to about two-third of its full range.
3. Adjust LEVEL to a comfortable listening level.
