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 thoroughly 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. If the measured voltage offers less than 0.1 V difference you've found the correct central, which should be clean and uncorroded.

MOUNTING & CONNECTIONS

Add a main fuse holder with appropriate fuse value to the (+) power cable in a distance of not more than 30 cm from the positive battery pole.

• Keep the wire connections as short as possible, in order to minimize power losses and preserve full power output of the system.
  ■ To minimize damage to the cables, take care that they do not pass through sharp edged metal. Use rubber grommets were required.
  ■ Lay all cables as far away as possible from the ignition cables, modules in the boot and under the dashboard, as these create interference.
  ■ The power cable should have a cable cross section of 10 mm ² (8 Gauge AWG). Smaller cross sections are reducing the output power, are causing distortions and may be triggering the overheat protection of the amp-module.

WIRING & CONNECTIONS

IMPORTANT:

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

Connect this lead only after having completed and checked all other connections. The positive power cable (+12V) must be connected directly to the positive terminal of the vehicle battery to provide an adequate voltage source.

GROUND CONNECTION

The ground terminal (GND) connection is also critical to the correct operation of the amplifier. Use a wire of the same gauge as the +12V cable and connect it between the ground terminal (GND) of the amplifier and a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or rust at the grounding point should be scraped away to provide a clean metal surface to which the end of the ground wire can be screwed or bolted.

REMOTE TURN-ON CONNECTION

The amplifier is turned on by applying +12V to the remote turn-on terminal (REM). The wire lead to this terminal should be connected to the "Amp remote" lead from the car stereo which will provide the +12V only when the car stereo is turned on.

INPUT CONNECTIONS

This amplifier features both high level and low-level (RCA) input capability. Use either the low-level RCA or high-level inputs, not both. If the car stereo does not provide RCA outputs, the amplifier may be connected via the speaker (high-level) outputs from the car stereo. Wire the speaker leads from the car stereo to the 4-pin adaptor harness as shown in the diagram (shielded cables are not required for this application) and plug the connector into the high input connector on the amplifier.

Connect the wires to the loudspeaker leads in the vehicle, as indicated on the amp-module.

NOTE:

When using the high-level input of your OE factory radio set "Auto turn-on" to ON. The AXB25A will cause a slight turn-on and turn-off noise in this mode, which is completely normal.

NOTE: Both RCA inputs must receive input signal from the head unit. Use a Y-ter if your head unit only features a mono subwoofer lead.

DANGER: Use the specified 20A ATC fuse for replacement only. Higher ampera-day cause serious damage or even a fire.

ADJUSTMENTS

Turn-on your head-unit keeping your volume in a low setting. The green status LED on the front of the AXB25A amp-module should light up now. If not, turn-off your head-unit and re-check all wiring to and from the amplifier for missing or faulty connections.

PROTECTION INDICATOR

This active subwoofer is equipped with an overload protection. In case of internal short circuit or increased temperature, the overload protection is activated, and the red LED indicator comes on.

The lowpass cut-off frequency setting, marked as „Crossover" on the active subwoofer, depends on the dimension of the vehicle and the mounting location. As a rule of thumb, settings in a range between 80 to 100 Hz will render best sonic results. For an intermediate lowpass crossover setting to attempt input gain and phase-shift control adjustments, go for a VR-pot set to approx. 80 Hz – and after input gain has been adjusted, it is advisable to fine tune the lowpass crossover frequency for best possible sound quality.

INPUT GAIN

The input level control allows the AXB25A to be matched to almost any head unit, to work well within a wide range of output levels. The following procedure can be applied: Turn on the head unit and adjust the volume level to an elevated but still sane output. Now using a screwdriver, increase the GAIN potentiometer by turning it clockwise (on the AXB25A side panel) until the bass content is perceived as sufficient and balanced.

PHASE-SHIFT

Adjust the potentiometer of the Phase-Shift control from 0° to 180° and listen for changes in the bass reproduction quality. A particular setting within the available range of control will give you more or better bass (more precise) around 100 Hz.
