AMPLIFIER LOCATION & MOUNTING
1
The mounting location of the power amplifier will have a large
effect both on its ability to dissipate the heat generated during
normal operation through the heat sink and on the possible triggering
of its internal overheat protection shut-off circuit. Any mounting po-
sition allowing for a good air stream across the cooling fins of the
amplifiers heatsink will improve cooling and long-term stability
dramatically.
With the AXTON amplifier series the most efficient ventilation is
achieved when the units are installed standing up!
Therefore select a suitable location that is convenient for mounting and
accessible for wiring and offers sufficient ventilation for cooling. As your
amplifier features no controls for normal operation, it may be mounted
away from the dashboard, i.e. under a car seat or in the trunk. However,
make sure the unit is not exposed to excessive dust, direct sunlight,
humidity, water, oil or other fluids that may enter the amplifier.
2
The amplifier should be mounted to a solid surface that will ensure
a vibration-free mount. Once the location is selected, use the unit
as a template for the marking of the mounting holes which should also
be pilot-drilled before mounting of the amp is carried out.
3
Secure the amplifier using the four screws. Avoid to let the amp-
lifier get into contact with metal parts of the vehicle. This helps
to prevent unwanted ground loops.

WIRING TIPS
Please note: wrong power or signal connections may damage the am-
plifier and other components connected to it. Therefore, please read
this manual carefully before the connection of any power, signal and
speaker leads is done.
The wire routing is critical for noise-free performance. For best results,
please follow the general wiring guidelines listed below (for details see
section B, E, F and G of this manual).
1
For audio signal connections you should always use double or
triple shielded quality RCA cables.
2
Signal, speaker and power cables should always be kept as short
as possible:
™ Speaker and power cables may be cut to fit the actual length
required.
™ Shielded RCA/signal cables should never be cut and respliced,
as they will loose their protective shielding effect at those points
where they have been cut. If the signal cable is too long, make an
S-type loop (never a coil loop) in the centre of the cable to take-up
the excess length.
3
Never route any low level/signal cable near or parallel to speaker
outputs/speaker cables, amplifier power cables or high energy
ignition wires.
4
Use power cable with the recommended cross section (see
section E). Small cross sections are reducing the output power,
are causing distortions and may be triggering the overheat protection
of the amplifier.
