3. AMPLIFIER MOUNTING

Attention! For your own safety, disconnect the negative battery terminal (GND) before you

start any wiring work!

Before you proceed to install this AXTON amplifier, it is recommended to map out the

complete system and the respective wiring required. Consider all additional electrical

requirements and accessories, such as power cables, interconnect cables etc., to complete

the install. Please note that - because of possible interference problems with the existing car

electrics and electronics, especially the routing of the signal cables and the chassis ground

connection will have a profound impact on the trouble-free (noise free!) operation of the

amplifier.

The mounting location should be carefully selected and in the interest of passive driver and

passenger safety, the amplifier must be securely mounted. Make sure that there is no wiring

harness, fuel tank etc. behind or below the mounting surface that may be damaged by the

drilling of the holes for the amplifier mounting screws. After installation, there should be a

clearance of at least 5cm to all sides including the top of the amplifier heatsink. Make sure

the unit is not exposed to direct sunlight, humidity, water, oil or spill of other fluids that may

enter the amplifier.

Once the location where the amplifier will be mounted is determined, use the unit as a

template for the marking of the mounting holes with pencil or felt-tip marker. The mounting

holes should be pilot-drilled, using a 2,5 mm or 3 mm drill bit. Bolt the amp down.

Important! There must not be a direct contact of the amplifier heatsink, bottom panel

or any other metal part of the amplifier to the vehicle metal panel! Electrical ground-

loops will cause audible hum!

4. WIRE ROUTING

4.1 MAIN POWER WIRES

We recommend a minimum main power cable cross-section (5m total length) of 16 to

20 mm², for both the positive and the ground wires. Following these recommendations

guarantees a trouble-free operation of your amplifier, as well as full power output.

Run the positive main power cable („+12 V") directly from the positive terminal of the

car battery to the amplifier. For protection of your car audio system against electrical fire

hazards, resulting from a short-circuit of the main power cable to chassis ground a main

fuse holder must be inserted within the first 30 cm of the positive main power cable. The

applicable fuse value must be matched to the limitations of your main power cable and the

current draw of the amplifier – therefore choose an appropriate fuse value.

Attach the ground cable to the amplifier. In most cases it will be best to keep the ground

cable (GND) as short as possible, i.e. to find a chassis contact very close to the amplifier.

The ground power wire must have the same cross-section as the positive power cable. The

contact point where the ground wire is attached to, must be solid and clean, i.e. free from

rust or paint!

Tighten both power input terminals of the amplifier, and double check for perfect fit of both

main cable leads!

4.2 RCA & REMOTE WIRES

For best interference free transmission of the music signal, use double or triple shielded

RCA interconnects only. Twisted pair Interconnects offer excellent noise rejection as well.

Route the RCA interconnects away from potential sources of Interference, such as engine

computers, gas pumps, etc.

Carefully run the audio signal interconnects, the remote wire and – if applicable - the cable

of the bass level remote control (A100 and A500 only) from the head unit or dashboard

to the amplifier. As mentioned before, the audio signal cables should always be routed

completely separate from the power cables. Connect the remote (turn on/turn off) lead to the

respective input terminal of the amplifier and to the remote output of your head-unit. Now

you can connect the RCA interconnects to the respective outputs of your head-unit and to

the inputs of the amplifier by using the provided RCA input adapter. Pay attention to connect

the stereo interconnects correspondingly, left is 1CH, right is always 2CH a.s.o.

4.3 HIGH-LEVEL INPUT

For longer distances from the head unit to the input section, it is best to use 1.0 mm

1.5 mm

speaker cables to avoid a loss of power or risk degradation of the signal quality.

Once the speaker cables have been routed, connect them to the speaker cable input

adapter. Maintain correct polarity ("+" to "+" and "-" to "-"). When using the high-level input,

you can chose the Auto-Turn-On function "VOX" or "DC" instead of running a separate

remote wire to turn on the amplifier. "VOX" turns on the amplifier when it recognizes an

audio signal. "DC" is using the DC voltage of the head unit's internal speaker amplifier.

The Axton amp will then turn on/off according to the head unit's state automatically. We

recommend using the "DC" mode.

For best installation comfort you can purchase the optional plug & play connector N-A400-

ISO and the car-specific Axton adapter N-A480DSP-ISOxx. That way you are able to install

the amplifier very quickly and without any damage to the original head unit and speaker

wires. Ask your Axton dealer for further information.

4.4 LOUDSPEAKER WIRES

For longer distances to the speakers, it is best to use 1.5 mm

avoid a loss of power or risk degradation of the signal quality.

Once the speaker cables have been routed, turn loose the screws of the speaker terminal

binding posts and – after inserting the stripped and bare speaker cable ends – re-tighten the

screws. Maintain correct polarity ("+" to "+" and "-" to "-").

Close the electrical circuit by attaching the ground wire to the battery and switch on your

head unit. If the status LED does not illuminate, your installation is wrong! Immediately turn

off your head-unit and carefully recheck all installation and wiring steps!
