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 nor-
mal operation through the wide heat sink and on the possible trigge-
ring of its internal overheat protection shut-off circuit. Any mounting
position allowing for a good air stream across the cooling fins of
the amplifiers heatsink will improve cooling and long-term stabi-
lity 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 sun-
light, humidity, water, oil or other fluids that may enter the amplifier.
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 and the rubber grom-
mets provided. The rubber grommets are not also reducing possi-
ble vibrations, they are also intended to insulate the amplifier from
contact with the car’s body metal/chassis ground. This helps to elimi-
nate 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 spea-
ker leads.
The wire routing is critical for noise-free performance. For best re-
sults, please follow the general wiring guidelines listed below (for de-
tails 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 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
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 spea-
ker outputs/speaker cables, amplifier power cables or high ener-
gy ignition wires.
4
Use power cable with the recommended cross-section (see sec-
tion E). Small crosssections are reducing the output power, are cau-
sing distortions and may be triggering the overheat protection of the
amplifier.
