Installation Instructions
Step #3 Wiring Your Powered Subwoofer
Next, attach the main power lead (yellow wire) to a constant 12 volt power
source. It is best to connect it directly to the positive lead of your battery.
Then, connect the ground lead (black wire) to the chassis of your vehicle.
Make sure to remove any paint or residue at the ground point to achieve
good, consistent ground contact. Connect the remote turn-on wire (blue/
white) to the amplifier turn-on lead at the back of the radio. This will turn
the powered subwoofer on when the radio turns on, and turn the powered
subwoofer off when the radio turns off.
Finally, plug your radio’s low-level RCA outputs (dedicated subwoofer
output) into the RCA inputs (5) on the SUB8100. For radios that do not
have a dedicated subwoofer output, follow the instructions on the next
page to connect directly to the SUB8100’s high-level inputs.
Your powered subwoofer comes with a remote gain control that allows you
to remotely adjust the gain. To use this control, you must plug it into the
remote gain input on the front of the powered subwoofer (3). The remote
gain control can be mounted under the dash or any other convenient
location. Make sure you don’t mount it anywhere that could interfere with
driving.
CAUTION: DO NOT PLUG OR UNPLUG THE REMOTE GAIN
CONTROL WHILE THE AMPLIFIER IS POWERED ON.
