Radio Shack XL-110 - Manual (Page 6)

6 Preparation
Cautions:
• For added safety and to protect your
amplifier and auto sound system, dis-
connect the cable from your vehicle’s
negative (
– ) battery terminal before you
begin.
• Be sure your speakers can handle as
much as 110 watts of power (55 watts
per channel). Each speaker must have
an impedance of at least 4 ohms. Your
local RadioShack store has a large vari-
ety of speakers.
To make it easier to gauge wire length and
connect the amplifier, temporarily place the
amplifier as close as possible to the selected
mounting location.
CONNECTING GROUND AND SWITCHED/PRIMARY POWER
Follow these steps to connect the amplifier to
ground, switched power, and primary power.
1. If you have not done so already, discon-
nect the cable from your vehicle’s nega-
tive (
– ) battery terminal.
2. Use a screwdriver to connect the spade
end of the supplied black ground wire to
the amplifier’s
GND (ground) terminal.
3. Connect the black ground wire’s other
end to a chassis ground, such as a
metal bolt attached to a metal part of the
vehicle’s frame. Be sure the bolt is not
insulated from the chassis by a plastic
part.
4. Use a screwdriver to connect the spade
end of the supplied blue/white wire to
the amplifier’s
REM (remote power) ter-
minal.
5. If your auto sound system has a
switched power lead, connect the blue/
white wire’s other end to your auto
sound system’s switched power lead
