The black cable is ground. When installing

this unit or power amp (sold separately), make

sure to connect the ground wire first. Ensure

Secure the wiring with cable clamps or ad-

hesive tape. Wrap adhesive tape around

wiring that comes into contact with metal

parts to protect the wiring.

Place all cables away from moving parts,

such as the gear shift and seat rails.

Place all cables away from hot places,

such as near the heater outlet.

Do not connect the yellow cable to the bat-

tery by passing it through the hole to the

engine compartment.

Cover any disconnected cable connectors

with insulating tape.

Do not shorten any cables.

Never cut the insulation of the power cable

of this unit in order to share the power

with other devices. The current capacity of

the cable is limited.

Use a fuse of the rating prescribed.

Never wire the negative speaker cable di-

rectly to ground.

Never band together negative cables of

multiple speakers.

When this unit is on, control signals are sent

through the blue/white cable. Connect this

cable to the system remote control of an exter-

nal power amp or the vehicle s auto-antenna

relay control terminal (max. 300 mA 12 V DC).

If the vehicle is equipped with a glass anten-

na, connect it to the antenna booster power

supply terminal.

Never connect the blue/white cable to the

power terminal of an external power amp.

Also, never connect it to the power terminal of

the auto antenna. Doing so may result in bat-

tery drain or a malfunction.
