Connecting the Unit
Connecting the Speaker wires
The speaker output mode can be two-channel (stereo) or one-channel
(mono). Connect the speaker leads to suit the mode according to the figures
shown below.
• Do not connect both the RCA input and the speaker input at the same time.

• To ensure proper installation, use the supplied
parts in the manner specified. If any parts other
than the supplied ones are used, they may damage
internal parts of the amplifier, or they may
become loose causing the amplifier to shut down.
CAUTION:
To prevent malfunction and/or injury
• To ensure proper heat dissipation of the amplifier,
be sure of the following during installation.
Drill a 2.5 mm diameter hole
—Allow adequate space above the amplifier for
proper ventilation.
—Do not cover the amplifier with a floor mat or
carpet.
• Do not install the amplifier near a door where it
may get wet.
• Do not install the amplifier on unstable places
such as the spare tire board.
• The best location for installation differs with the
car model and installation location. Secure the
amplifier at a sufficiently rigid location.
• Make temporary connections first and check that
the amplifier and the system operate properly.
• After installing the amplifier, confirm that the
spare tire, jack and tools can be easily removed.
