Wiring Connection - Ground Zero GZRA 2100XII Anleitung

DO NOT enclose the amplifier in a small box or cover it so that air cannot flow
around fins.
Temperatures in car trunks have been measured as high as 175'F (80° C) in the
summer time, since the thermal shut down point for the amplifier is 185'F (85° C) it
is easy to see that it must be mounted for maximum cooling capability. To achieve
maximum advantage of convection air flow in an enclosed trunk, mount the amplifier
in a vertical position, on a vertical surface.
Cooling requirements are considerably relaxed when mounting inside the passenger
compartment since the driver will not often allow temperatures to reach a critical
point. Floor mounting under the seat is usually satisfactory as long as there is at least
1 inch (2,5cm) above the amplifier's fins for ventilation.
• Select a suitable location that is convenient for mounting, is accessible for wiring
and has ample room for air circulation and cooling.
• Use the amplifier a template to mark the mounting holes, remote the amplifier
and drill 4 holes (use extreme caution, inspect underneath surface before
drilling!)
•
Secure the amplifier using the screws provided

Wiring connection

A. Connecting the power
CAUTION
As a precaution, it is advisable to disconnect the vehicle's battery before making
connection to the +12 (24) volts supply wiring (see your cars instruction for that
matter).
4 Gauge (min 16mm² / 0.63", thicker if planning for additional amplifiers) wire is
recommended both the power and ground wires. 12 gauge for the remote turn- on
wire. Both types are available at most mobile audio dealers or installation shops.

(1) GROUND: to vehicle chassis
To avoid unwanted ignition noise caused by ground loops, it is essential that the
amplifier be grounded to a clean, bare metal surface of the vehicles chassis.
NOTE: Ground wire should not be extended more than 3 ft. (1 m).
(2) +12 Volt (fused) constant power: to battery (+)
Due to the power requirements of the amplifier, this connection should be
made directly to the positive (+) terminal of battery. For safety measure,
install an in-line fuse holder (not included) as close to the battery positive
(+) terminal as possible with an ampere rating: not to exceed total value of
fuses in amp.
(3) Remote turn- on input: to power antenna output of car stereo
This amplifier is turned "ON" remotely when the vehicle's stereo is turned
"ON".
NOTE: If your radio does not have +12 Volt output lead when the radio is
turned on, the "REM" terminal of the amplifier can be connected to
vehicle's accessory circuit that is live when the key is "ON".
