Tools and materials you need
•Screwdriver
•Electric drill, 3 mm / 0.12” carbide drill bit
•Mounting screws
•Power wire min. 25 mm² / 4AWG
•Ground wire min. 25 mm² / 4AWG
•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 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
capacitor (power cap) min. 1 F 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 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.

Speaker terminals
For connection of the subwoofer
2
Power terminals
GND -> Ground connection
REM -> Remote antenna terminal
BATT -> +12 Volt
3
Satus indication
GREEN – OK
RED – Error
4
Cinch inputs
Terminal for connection of the RCA wires.
To avoid failure, please use high quality RCA wires.
5
Input level controller
With this controller you can adjust the input sensitivity.
6
Bass boost controller
For adjusting of the bass boost level in the range from 0 to +12 dB.
7
Low pass controller
Adjust the variable lowpass frequency to the desired frequency between 30
and 250 Hz using the controller.
8
Master / Slave Switch
For choosing the operation mode of each amplifier in link mode.
9
Cinch Outputs
For connection of additional amplifiers in fullrange operation.
10
Remote control input
For connection of the bass remote control.
11
Phase shift controller
This controller allows you to fit the subwoofer channel in-phase to the front
system.
12
Subsonic controller
This controller allows you to filter low frequencies in a range between 10
and 50 Hz. This function reduces the mechanical Xmax and raises the
capacity of the connected subwoofer.
13
Master/Slave
Cinch-In-/Output
Cinch In- / Output for operation of two same amplifiers (2x GZTA
1.800DX or 2x GZTA 1.1200DX) in linkmode.
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.
