installation will vary from application
to application. Carefully consider as
many installation locations and
configurations as is practically
possible. DO NOT COVER the
powered subwoofer with carpet or
enclose it behind interior panels.
DO NOT mount inverted or upside
down. The amplifier may be
mounted vertically.
Connect the fused 12 Volt DC
power wire, chassis ground cable,
and remote wires. (SEE SECTION 3,
ELECTRICAL CONNECTIONS)
Turn on the car stereo. If the Power
Protection light is green, turn off the
stereo and proceed to the next
section. If the Power Protection light
is red, review all of the connections
and wires. You may have a loose
connection, a bad chassis ground, or
an inadequate size power wire. If the
problem persists after reviewing all
of the connections and wires, call
our toll-free help line for assistance.
Do not mount inverted or

STEP 1.
STEP 2.
STEP 3.
STEP 4 .
Attach the supplied brackets to the base of the Powered Subwoofer
using the 4 Phillips Pan Head Screws.
(FIG. 1)
1. Power Terminal
1.
Strip 1/2” of insulation from the end of the minimum 10 gauge power
wire. Connect the 10 gauge power wire to the battery terminal for the
LS-SUB-100.
2.
Loosen screw to open battery and ground connector plates on
rear of amplifier.
3.
Insert the 10 gauge wire between the connector plates. Turn screw until
power cable is tight.
2. Remote Terminal
The REMOTE wire connection automatically turns on your amplifier when
your stereo is tuned on. On most stereos, this wire is marked as the
REMOTE, ACCESSORY, or POWER ANTENNA.
1.
Locate the REMOTE, ACCESSORY, or POWER ANTENNA on the stereo.
(Refer to you stereo owner’s manual.)
2.
Splice the REMOTE, ACCESSORY or POWER ANTENNA wire from rear of
the stereo to a length of wire that will reach the rear of the amplifier.
3.
Loosen screw and open REMOTE connector plates on rear of amplifier.
4.
Insert wire end between the REMOTE connector plates.
5.
Tighten screw closing REMOTE connector plates on wire.
3. Ground Terminal
1.
The ground connection cable should be attached to clean, unpainted
chassis metal for a good electrical connection.
2.
Find good, no-rusted chassis metal, as close to the amplifier as possible.
3.
Drill a pilot hole with a 1/16” drill bit.
4.
Use sandpaper to expose an area of bare metal around the pilot hole
about the size of a dime.
5.
Tightly fasten the provided ground cable with self tapping sheet metal
screw to the chassis metal. A loose ground will cause distortion and
popping noises in the speakers.
Carpet Mount
Cut a piece of plywood 22” x 11”
and slide it under the carpet where
the Powered Subwoofer will be
mounted and proceed to step #4.
