Operation Manual

3. AMPLIFIER MOUNTING

Attention! For your own safety, disconnect the positive battery terminal (+12V) or

remove the main fuse in the positive power cable near the car battery, before you

start any wiring work!

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

audio system and the respective wiring required. Consider all additional electrical requirements and

accessories, such as power cables, interconnect cables etc., to complete this 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 a trou-

ble-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 ampli-

fier mounting screws. After installation, there should be a clearance of at least 5cm on all sides includ-

ing 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 defined, 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-dril-

led, using a 2,5mm or 3mm drill bit. For the actual mounting, always use the supplied rubber washers

before attaching the amp to the panel with the supplied mounting screws.

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! Electrical ground-

loops can result in audible hum!

4. WIRE ROUTING

4.1 MAIN POWER WIRES

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 – the-

refore choose an appropriate fuse value.

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

(„-12V“) 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!
