Ground Connection; Input Mode Switch - Rockford Fosgate POWER 1000 MOSFET Owner's Manual

voltage drop and low noise. If the power is connected to any
other point (the fuse block, for instance) the amplifier's power
output will be reduced and oscillations and noise may distort the
sound. If the power wire must be extended, use only 6-gauge or
larger wire and make 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 amplifier; it wil induce
noise.
Avoid running the Orange power wire near the radio's antenna
or power leads, or near sensitive equipment or harnesses. The
Orange power wire carries substantial currents and could
induce noise.
The Orange wire is provided with an in-line 100 ampere fuse. Do
not use a larger fuse or the amplifier will not be adequately
protected, and you risk damage to your car's electrical system.
GROUND CONNECTION (BLACK 6-GAUGE WIRES)
The ground wires must be connected directly to the car chassis,
near the amplifier. Connect the ground wires to separate spots
on the chassis at least one foot apart. Ground loops are
aggravated by the length of the ground wire orany resistance in
the ground path. For this reason we don't recommend extending
the ground wires in any installation.
The ground points in the car should be pieces of chassis metal
that are welded to the main body of the car. Painted surfaces
should be scraped or sanded clean before the ground lugs are
bolted down. (Cover the bare-metal areas with paint or grease to
prevent rust.) A dab of Panduit CMP-200-1 between the lugs and
the chassis will improve grounding performance.

INPUT MODE SWITCH

The input of the Power 1000 MOSFET normally comes from the
2-channel/4-channel
some cases where it is desirable to be able to drive the rear
channels independently. For instance, if one wanted to drive the
system as two completely independent stereo amplifiers, one
would need to drive the front channel with one stereo pair, and
the rear channel with another.
front RCA connectors. However, there are
