MOUNTING
Note that the amplifier generates heat, so a well ventilated mounting place
n
is necessary or it will easily overheat.
Keep the wire connections as short as possible, with sufficient length, in order to
n
minimize power losses and provide a higher audio output of the system.
For safety reasons route all power and speaker wiring by using the existing
n
wire channels.
To minimize damage to the cables, take care that they do not pass through sharp
n
edged metal. Use rubber grommets were required.
Lay all cables as far away as possible from the ignition cables, modules in the boot
n
and under the dashboard, as these create interference.
Keep the length of the power cable as short as possible.
n
The power cable should have at least a cable cross section of 10 mm
n
AWG). Smaller cross sections are reducing the output power, are causing
distortions and may be triggering the overheat protection of the amplifier.
Important:
Add a main fuse (60 A) to the (+) power cable in a distance of not more than
30 cm from the positive battery pole (fire hazard!)
1. Position the mounting brackets.
2. Use the tapping screws to fix them.

WIRING INSTRUCTIONS
Important:
Before any wiring, always remove the negative terminal of the battery to
prevent short-circuiting. This is also the last lead to be (re-)connected.
Connect this lead only after having completed and checked all other connections. The
battery terminal (+12V) must be connected directly to the positive terminal of the vehicle
battery to provide an adequate voltage source and minimize noise. Connecting the battery
terminal lead to any other point (such as the fuse block) will reduce the power output and
may cause noise and distortion. Connect it to the terminal of the battery after all other wir-
ing is completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation of the ampli-
fier. Use a wire of the same gauge as the power connection and connect it between
the ground terminal (GND) of the amplifier and a metal part of the vehicle close to the
mounting location. This wire should be as short as possible and any paint or rust at the
grounding point should be scraped away to provide a clean metal surface to which the
end of the ground wire can be screwed or bolted.
REMOTE TURN-ON CONNECTION
Using the RCA low level input, the amplifier is turned on by applying +12V to the remote
turn-on terminal (REM). The wire lead to this terminal should be connected to the „Amp
remote" lead from the car stereo which will provide the +12V only when the car stereo is
turned on. If the car stereo does not provide an „Amp remote" lead, the remote turn-on
lead may be wired to an „Accessory"or „Radio" terminal in the car's fuse block. This will
turn the amplifier on and off with the ignition key, regardless of whether the car stereo is
on or off. The remote turn-on lead does not carry large currents. So a thin wire may be
used for this application. The Auto-Turn-On feature is only available when using the high
level inputs.
INPUT CONNECTIONS
This amplifier features both high level and low-level input capability. Use either the
low-level or high-level inputs, not both. If the car stereo does not provide low-level outputs,
the amplifier may be connected via the speaker (high-level) outputs from the car stereo.
Wire the speaker leads from the car stereo to the 4-pin adaptor harness as shown in the
diagram (shielded cables are not required for this application) and plug the connector
into the high input connector on the amplifier.
