lites front and rear component or coaxial systems) with an impedance of at
least 2 ohms and one subwoofer channel for the bass reproduction at a mi-
nimum load impedance of 2 ohms. The front- and rear- speaker outputs of
the EA490-200 are not bridgeable. For speaker connecting reference
see fig.3 or the system configurations overleaf. Should you intend to use only
one pair of satellites (plus subwoofer) with this amplifier, they have to be
connected to the „Front Speakers" terminals with the amplifier switched to
„4-CH INPUT MODE".

2.5 Mounting the Amplifier
Once the location for the amplifier is defined, use the unit as a template for
GND
the marking of the mounting holes with a pencil or felt-tip. The mounting ho-
les should be pilot-drilled using a 2,5mm or 3mm drill. For the actual mo-
unting the supplied rubber washers have to be pressed into the mounting ho-
les from the top before inserting the supplied mounting screws. The rubber
washers protect the amplifier from electrical ground-loops that can easily re-
sult in audible hum!

2.6.1 Wiring / Electrical Connection

IMPORTANT NOTICE: Disconnect the positive battery terminal
(+12V) or remove the main fuse near the car battery before
any wiring work! Please note that the power supply of the
car must remain disconnected, until the entire wiring instal-
lation is completed.
Speaker Impedance Specifications
The heat dissipation capacity of this 5-channel amplifier has been designed
to operate with two pairs of satellites with a minimum impedance of 2 ohms
(per satellite) and a subwoofer channel with a minimum impedance of 2
ohms. These minimum impedances must not be decreased any further, as
