RCA Input Jacks
Connect these jacks to the line out leads on your
head unit using RCA extension cables (sold
separately). Be sure to observe correct channel
connections; Left to Left and Right to Right.
NOTE:
• Use either RCA line level or speaker level
inputs. Do not connect both at the same time.
Pre-Out Jacks
These jacks provide a line level output. This is an
ideal output for driving a second subwoofer
amp. This output is full-range, and is not affected
by the crossover.
Remote Bass Control Jack
Connection Cable
Remote Bass Control Unit
The Remote Bass Control Unit adjusts the output
level remotely. This is not to replace appropriate

About Power supply wires
If the length of the power and ground cables
exceed 1 m, or if you connect more than one
amplifier, a distribution block should be used. See
below for wire gauge recommendations for
distribution block connection to battery and
ground (depends upon wire length necessary):
2 AWG (33 mm
2
) or 1/0 AWG (53 mm

)


 Connect all equipment to the same ground point while
keeping wire length as short as possible.
Ensure that you install a correctly-rated in-line fuse
on the power cable near the battery positive post.
Cautions on wire lead connections
When using third-party wire cables (power supply
wire), use the supplied screws to simplify the
connection. Refer to the description below for the
proper procedure. If you are in doubt about how to
make this connection, consult your dealer.
1. Check the wire size.
• Required Wire Size
– Battery Lead/Ground Lead ....4 AWG (21 mm
2
)
– Remote Turn-On Lead .............12 AWG (3 mm
2
)
– Speaker Output Lead ................8 AWG (8 mm
2
)
• If the wire gauge used is unknown, ask your
dealer.
