AMPLIFIER LOCATION
1
The mounting location of the power amplifier will have a large ef-
fect 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 mo-
unted 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 ampli-
fier.
2
The amplifier should be mounted to a solid surface that will en-
sure 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 final securing with the provided
screws is carried out.
3
Secure the amplifier using the four screws. Avoid to let the am-
plifier get into contact with metal parts of the vehicle. This helps
to eliminate 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.
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 tri-
ple shielded quality RCA cables.
2
Signal, speaker and power cables should always be kept as
short as possible:
™ Speaker and power cables may easily be cut to fit the actual
lengths required.
™ Shielded RCA/signal cables should never be cut and respliced, as
they will loose their protective shielding effect at those points whe-
re 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 crosssections are reducing the output power,
are causing distortions and may be triggering the overheat protection
of the amplifier.
