2.3 SPEAKER IMPEDANCES & WIRE INFO

The heat dissipation capacity of this amplifier has been designed to cope with low impedance loads.

However, EMPHASER laboratories recommend to stay at or above the suggested impedance ratings

listed below:

➡

EA450-250

subwoofer channel 2 ohms / satellite channels 2 ohms stereo or 4 ohms bridged

Note: EMPHASER laboratory recommends a minimum main power cable cross-sec-

tion (5m total length) of 20 to 25 mm

These recommendations guarantee trouble-free operation of your amplifier, giving you full power out-

put.

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.
