Connecting the Power Terminal

Always use the special red battery and ground wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body.

1. Pass the battery wire from the

engine compartment to the interior

of the vehicle.

• After making all other connections to the

amplifier, connect the battery wire terminal of

the amplifier to the positive (+) terminal of

4.Connect the wires to the terminal.

Fix the wires securely with the terminal screws.

4. Push on the terminal cover.

Connecting the Speaker wires

The speaker output mode can be two-chan- nel (stereo), one-channel (mono), or three- channel (stereo + mono). Connect the speaker leads to suit the mode according to the figures shown below.

capacitance (C) will determine the frequency (fc)

that the speaker will reproduce. Refer to the chart

below to determine the components required.

• Use the capacitors specified. Non-polarized capac-

itors rated at over ±25 V should be used for C1

and C2 in the diagram. Because of the voltage

output of the amplifier, it is very important to use

non-polarized capacitors rated at or over 25 V.

This will prevent a safety hazard.

Three-channel mode (stereo + mono)

The power amplifier is basically a two- channel/one-channel bridgeable amplifier, but three channels can be achieved by combining the stereo and mono modes using inductors and capacitors.

Inductors (L1 and L2 in the diagrams) act as low-pass filters. Capacitors (C1 and C2 in the diagrams) act as high-pass filters. Inductors (L) are used for the woofer/subwoofer, and capacitors (C) are used for the high/mid-high.

Remember when bridging an amplifier it will see only half of the original speaker impedance. Therefore, you must use speakers that have ratings of 4 ohms or higher. If you use speakers that have lower impedance ratings it may cause damage to the amplifier.

When the inductors and capacitors are connected to the speaker wires, secure or solder them so they cannot be pulled loose. Tape or use heat shrink on the joints to prevent short circuits.
