Connecting
Follow all mounting and wiring instructions to ensure the integrity of existing wiring after installation.
Before connecting:
Disconnect the vehicle's battery before making connection to the +12 volt supply wiring.
Power input terminal connecting
1. Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this
ground wire to less than 39" (100 cm) in length. Use 8 gauge (or heavier) wire.
2. Connect the remote terminal to the remote output of the head unit using 16 gauge (or
heavier) wire.
3. Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 8 gauge (or
heavier) cable from this fuse to the amplifier location. Check that the fuse holder is empty.
Then connect the fuse holder to the "BATT+" connection on the amplifier.
4. Connect all line inputs and outputs (if used) using high-quality cables. Connect all speakers,
following the diagrams in this manual. Be sure to observe proper polarity to avoid audio
phase problems.
5. Insert fuse into battery fuse holder.
6. Recheck all connections before powering up the subwoofer.
7. Set all level controls to minimum position, and set all crossover control/switches to the
desired frequency points.
8. Power up the head unit and the subwoofer. Then set the volume control on the head unit to
about 3/4 volume, and adjust the subwoofer's input level controls to just below the level of
distortion.
9. Further fine tuning of the various controls may be necessary to obtain best results.
Notes:
Separate audio and power wiring to avoid interference.
All wires and connections must be insulated with electrical tape, and filter with
protective connector shields where ever possible.
Before replacing blown fuse check and verify that there is no short cut at all connections.
Low level input connecting
Low-level (RCA) input wiring is preferred for best audio performance. most trunk
or hatchback installations will require a 15-20 foot RCA cable, while pickup
trucks and under-seat installations will require a 6-12 foot RCA cable. Always use
a high quality cable.
