SAFETY INSTRUCTIONS
1. This unit is designed to be used in a vehicle with a 12 V battery and negative ground.
2. 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.
3. Do not disassemble or alter the unit in any way, because that will also void your warranty. Do not
attempt to repair or to service the unit yourself, but contact an authorized AXTON dealer instead.
4. Use only original accessories which are designed and manufactured for the unit, otherwise you will risk
to damage it. Install the unit according to the mounting manual and use only the supplied mounting
accessories. The forces of acceleration for accidents are sometimes huge. Incorrect mounted units are
a big risk for the driver and the passengers of the car, during an accident.
5. Protect the unit from water and other liquids, which can enter the casing. A short circuit or even fire
could be the result.
6. Before you replace a defective fuse, try to find the cause for the short circuit. Please pay attention
to the cables of the power supply! If the short circuit doesn‘t result from a failure of the power supply
or wiring, you can replace the defective fuse with a new one of identical value. If the short-circuit still
exists, please contact an authorized AXTON dealer.
7. Be careful not to drain the car battery while using the unit when the car engine is turned off. Because
the unit uses a considerable amount of energy and the battery will be charged only while the engine is
running, it might happen that the battery will discharge to a point where it‘s no longer possible to start
the engine.
8. If your car is parked in direct sunlight and there is a considerable rise in temperature inside the car,
allow the unit to cool off before operation.
9. Please pay attention to the volume inside your vehicle, because you are obliged to notice exterior
sounds like a police siren or you might face penalties in case of an accident or even lose your insurance
cover.
INSTALLATION
1. Use the supplied cable and wire harness and connect the outputs properly as shown in the High-
Level and Low-Level wiring diagram as following. Use only one of the audio inputs; otherwise, it
may lead to audio interference.
A) Take the wire side of the supplied connecting harness. Connect the white wire to the left (+),
white/black to the left (-) speaker wire; and the grey to right (+), grey/black to the right (-) speaker
wire. Finally connect this High-Level input adapter with the Plug&Play harness of the amplifier
panel of the ATB25RS
