Tools and materials you need
• Screwdriver
• Electric drill, 3 mm / 0.12” carbide drill bit
• Mounting screws
• Soldering gun
• Power wire min. 8 mm² / 8AWG
• Ground wire min. 8 mm² / 8AWG
• Speaker wire min. 2 x 2,5 mm² / 13AWG
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 in your car. Your gas tank, brake lines or cables 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 capacitor (power cap) min. 1 F to guarantee a stable operation voltage.
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 electric 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.
If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse
of different type or rating may result in damage to this system which isn’t covered by the warranty.
Controls and functions
1
Input level controller
With this controller you can adjust the input sensitivity.
2
Subsonic controller
This controller allows you to filter low frequencies in a range between
15 and 25 Hz. This function reduces the mechanical Xmax and raises
the capacity of the connected subwoofer.
3
Low pass controller
Adjust the variable lowpass frequency to the desired frequency
between 40 and 400 Hz using the controller.
4
Remote volume control
On – If the bass remote controller is connected
Off – If the bass remote controller is not connected
5
Bass boost controller
For adjusting of the bass boost level in the range from 0 to +12 dB.
6
Phase shift controller
This controller allows you to fit the subwoofer channel in-phase to
the front system.

Status indication
GREEN – OK
RED – Error
8
High / Low switch
Switch between high and low level (RCA) input.

Amplifier connection
• The GZRA MICRO ONE comes with a power and signal connector cable. For a reliable connection we
strongly recommend to use the delivered
spade connections or solder the joints.
• Make sure input connectors are making good contact with input jacks of the amplifier to avoid shortage or
interruption
• Never use any other connector instead of the original Ground Zero connector. In case of a defective
connector cable, please contact the Ground Zero service.
Turning on the amplifier
The amplifier automatically turns on a few seconds after 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.
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.
