Connections
Power
1. Connect the +12V BATT terminal, using 12 gauge wire,
to the positive side of the vehicle’s battery. Be sure to install
a fuse within 1 foot of the battery and that is the same rating
as the fuse on the subwoofer.
2.
Connect the ground terminal, using 12 gauge wire, to
the frame of the vehicle, with as short of a run as possible, at
a bare metal surface; preferably scraped body sheet metal.
Do not use factory ground locations, seat bolts, or brackets
that are spotwelded.
3.
For aftermarket use connect the REM terminal to the
source remote turn-on leads. The REM terminal is not used
when using a source from a stock radio connected to the Hi
Level input of the subwoofer (the subwoofer auto-senses
the presence of audio and turns on or off automatically).
Audio
The subwoofer has two audio drive options. These are
either from the preamplifier output terminals or the loud-
speaker output terminals (high level) of the car stereo equip-
ment.
