POWER CONNECTION

(WHITE WIRE)
(WHITE WIRE)
The White wire [#16] must be connected directly to a positive
terminal of the battery or to the fuse block to provide a power
source with a low voltage drop and low noise. If the power wire
must be extended, use only 18-gauge
a good splice.
It is best to use as short a wire run as possible. DO NOT run the
power wire next to the input cabling to the pre-amplifier: it will
induce
Avoid running the White power wire near the radio's antenna or
power leads, or near sensitive equipment or harnesses. The
White power wire could induce noise.
The White wire is provided with an in-line 3/4 ampere fuse. Do
not use a larger fuse or the pre-amplifier will not be adequately

GROUND CONNECTION

(BLACK WIRE) (BLACK WIRE)
The ground wire [#17] must be connected directly to the vehicle
chassis, near the pre-amplifier. Ground loops are aggravated
by the length of the ground wire or any resistance in the ground
path. For this reason we do not recommend extending the
ground wire in any installation.
The ground point in the car should be a piece of chassis metal
that is welded to the main body of the vehicle. Painted surfaces
should be scraped or sanded clean before the ground lug is
bolted down. (Cover the bare-metal area with paint or grease to
prevent rust .)
