Connecting the Unit

Connecting the Speaker wires

The speaker output mode can be four-channel, three-channel (stereo +

mono) or two-channel (stereo, mono). Connect the speaker leads to suit the

mode according to the figures shown below.

• When either the RCA input or the speaker input is connected, RCA output

becomes functional. Do not connect both the RCA input and the speaker input at

the same time.

liquids.

• 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.

To prevent malfunction

• To ensure proper heat dissipation of the amplifier,

be sure of the following during installation.

—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.
