• If you use RCA input jack A only, speaker output for channel A, channel B and the SUB channel is

output from channel A.

• If you use RCA input jacks A and B only, output from channel A and channel B is unchanged, but out-

put from the SUB channel is a mixture of the channel A and channel B signals.

• If you use RCA input jack A and SUB only, channel A and channel B signals are output from channel

A, but output from the SUB channel remains unchanged.

• When not using RCA input jack B or SUB, do not connect anything to them.

• 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

• Do not install the amplifier on unstable places

Drill a 2.5 mm diameter hole

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.

Note:

• Specifications and the design are subject to possible modification without notice

due to improvements.

*Average current drawn

• The average current drawn is nearly the maximum current drawn by this unit

when an audio signal is input. Use this value when working out total current

drawn by multiple power amplifiers.
