SAFETY INSTRUCTIONS

1. This unit is designed to be used in a vehicle with a 12V battery and negative ground.

2. Before any wiring, always remove the negative terminal of the battery to prevent short-

circuiting.

3. Do not disassemble or alter the unit in any way, because that will 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 damage. Install the unit according to the mounting manual and

use only the supplied mounting accessories. The forces of acceleration for accidents are

sometimes huge. Heavy objects may pose a 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 product. A short circuit

or even fire could 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 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 not longer possible to start the engine.

8. The amplifier module employs a protection circuit to protect the woofer from amplifier

malfunction. The amplifier's protection circuitry will shut-off the amplifier in case of short-

circuit, overload DC offset and in case of overheat. In case the cause for protection

shut-off has been eliminated, the amplifier will operate normally again (green LED ON).

Otherwise the amplifier will continue to remain in protection mode.

9. Do not use the unit with a weak or old battery as its optimum performance depends on

a normal battery supply voltage of 12V.

10. Please pay attention to the music playback 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 loose your insurance coverage.

11. Do not operate the unit in any other way than described in this manual. Failure to follow

the instructions within this manual will void your warranty.

WIRING & INTERFERENCE

All advice on wiring, controls and adjustments are based on the assumption that

you are thouroughly acquainted with all the requirements and features of the entire

audio equipment connected to this powered subwoofer!

All cables are sources of interference. The RCA audio cables are prone to interference

pick-up. There is often interference caused by the alternator (buzzing or whining), ignition

(crackling) or other car electronics. Most of these problems can be eliminated by correct wire

routing. In doing so, read the following guidelines first:

Use only double- or triple shielded RCA interconnects for the wiring between RCA input of

the amplifier and line-outs of the head unit.

Lay the signal and power cables separately with enough distance from one another and

also from other wire harnesses in the car. The REM cable to the amp remote output of the

radio can be laid together with the signal cables. Avoid ground loops by laying the ground

wiring of all components to a center point in a star-like way.

You can find the best central point in measuring the voltage directly at the battery. Compare

this voltage value with the chosen ground point and the (+) terminal of the amplifier. lf the

measured voltage offers less than 0.1 V difference you've found the correct central, which

should be clean and uncorroded.
