WIRING
1.FUSE: A fuse of the proper size must be installed in line with the main power in
order to prevent damage to your wiring. It should be connected to the battery
positive terminal or as close to the battery as possible. Use the fuse holder and
fuse provided and replace only with the same size fuse. The LINEAR POWER™
401
uses a 5 amp AGC fuse.

WARNING: OVERFUSING WILL DAMAGE THE AMPLIFIER
2.MAIN POWER
The free end of the fuse holder wire should be connected to the large red wire
from the amplifier. IMPORTANT: Solder or crimp all connections. Connect the
other end of the fuse holder to the + terminal on the battery.
3.MAIN GROUND
Connect the large black wire to a solid frame member via a bolt or self-tapping
screw. If in doubt about the adequacy of the ground, extend the ground wire to
the negative battery terminal.
4.+12V FOR TURN-ON
The red and white wire is not a main power source for the amplifier, but acts as
an electrical switch to turn the amplifier on and off. It should be connected to the
power antenna lead from the radio. Where no power antenna lead exists, a
source of 12 volts connected through a toggle switch will do. DO NOT
CONNECT DIRECTLY TO A SOURCE THAT WILL LEAVE THE AMPLIFIER
PERMANENTLY ON, AS THIS WILL DRAIN THE BATTERY.
5.SIGNAL INPUT
The RCA (Phono) Jack inputs will accommodate either high or low level signals,
ranging from 200mv to 5 volts. For use with a high level source that is intended to
drive speakers directly, attach speaker leads to male RCA Plugs and insert into
the inputs. Make sure that the positive speaker leads are attached to the
striped wire of the high level adaptor.
6.SPEAKER OUTPUT
Connect the gray wire to the right speaker's (+) terminal. Connect the green wire
to the left speaker's (+) terminal. Connect one of the black wires to the right
speaker's (-) terminal. Connect the other black wire to the left speaker's (-)
terminal. (See wiring diagram next page)
