?
If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating.?Check that no unconnected cables or connectors are touching the car body. Do not remove caps from unconnected cables or connectors to prevent short circuits.
?Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail.?After installation, check that the brake lamps,winkers, and wipers work properly.

Speaker level input terminals (7)
When the genuine-accessory car stereo power is turned ON/OFF, check that the power to this unit has followed suit.
In some cases, the power control is not correctly operated by the genuine-accessory car stereo. If this is the case, connect the ACC or power control signal to the P.CON terminal.
?The genuine-accessory car stereo shall have a maximum power output of no more than 40 W.?Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage.
?Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage.
?Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF.
s Power terminal (234)
Connect to their respective terminals the power supply wire, and ground wire, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section.

Installation
Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver’s seat without any hindrances.
As generally accepted positions for its installation,places such as inside the trunk, etc. can be
considered.
?Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be damaged.?Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit.
?The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it.
?When making a hole under a seat, inside the trunk,or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage.?Do not install near the dashboard, rear tray, or air bag safety parts.
?The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct
driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident.
?After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.5-CHANNEL POWER AMPLIFIER

(?4 ′PROBLEM
POSSIBLE CAUSE
SOLUTION
No sound.
(No sound from one side.)(Blown fuse.)
The output level is too small (or too large).The sound quality is bad.(The sound is distorted.)
?Input (or output) cables are disconnected.
?Protection circuit may be activated.
?Volume is too high.
?The speaker cord is shorted.
The input sensitivity adjusting control is not set to the correct position.
?The speakers wire are
connected with wrong +/ -polarity.
?A speaker wire is pinched by a screw in the car body.?The switches may be set improperly.
?Connect the input (or output)cables.
?Check connections by referring to "Power indicator".
?Replace the fuse and use lower volume.
?After check the speaker cord and fixing the cause of the short,replace the fuse.
Adjust the control correctly referring to "Controls".
?Connect them properly checking the +/ -of the terminals and wires well.
?Connect the speaker wire again so that it is not pinched by anything.
?Set switches properly by
referring to "System examples".
System examples
The unit is a 5-channel amplifier incorporating 2stereo amplifiers and 1 monaural amplifier in a single body.
The stereo amplifier on one side is called amplifier A, while the one on the other side is amplifier B.The monaural amplifier is called the amplifier SUB.This unit is compatible with a large variety of
systems by combining the switches and functions described in the following.
1Fuse (25 A ′2)
2Power control terminal 3Battery terminal 4Ground terminal
5Amplifier A/B speaker output terminals
?Stereo Connections:
When you wish to use the unit as a stereo amplifier, stereo connections are used.
?Bridged Connections:
When you wish to use the unit as a high-output monaural amplifier, bridged
connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (-) SPEAKER OUTPUT terminals.)
6Amplifier SUB speaker output terminal
As this unit accepts speakers with a minimum impedance of 2 ohms, connect speakers with 2-ohm or higher impedance to these terminals.
7Speaker level input terminals
A center unit with no RCA output can still be
connected to the speaker output.
Again, even without a power control signal, the power is switched ON/OFF automatically by the speaker signal.
8HPF(High-Pass Filter) switch
When this switch is set to 80 Hz or 150 Hz,frequencies below the setting value will be cut.9INPUT SELECTOR (A/AB) switch This switch toggles the input signal of amplifier B.
?A position:
The input for terminal A is output from amplifiers A and B.
?AB position:
The input for terminal A is output from amplifier A, while the input for terminal B is output from amplifier B.
0INPUT SENSITIVITY control
Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuine-accessory car stereo.
Use the diagram on the right as a guide.
The sensitivities of amplifiers A, B and SUB can be adjusted independently regardless of the position of the input selector switch.
output, refer to the “Specifications” in the instruction manual of the center unit.
!RCA cable ground lead terminal
When using an RCA cable with a ground lead
attached, connect the ground lead to this terminal.
grounding. This unit will be damaged if the power source grounding wire is connected to this terminal.
@Amplifier A/B/SUB LINE IN terminal #SUB.CH LPF(Low-Pass Filter)FREQUENCY control
This control adjusts the frequency band output from this SUB channel.
$OPERATION switch This switch is used to select the operation mode of the amplifier.
?STEREO position:
The amplifier can be used as a stereo amplifier.
?MONO (Lch) position:
Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power monaural amplifier. (The input right signal is not output.)
%INPUT SELECTOR (AB/SUB) switch This switch toggles the input signal of amplifier SUB.
?AB position:
The input for terminals A and B input is mixed and output from amplifier SUB.
The input signal varies according to the setting
of the INPUT SELECTOR (A/AB) switch and the OPERATION switch.
?SUB position:
The input for the SUB terminal is output by amplifier SUB.
Power indicator
When the power is turned on, the Power indicator lights.
If the Power indicator does not light when the power is turned on, the protection function may be
activated. Check whether there is any indication of trouble.
s The protection function is activated in the following situations:
This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur.
When the protection function is triggered, the Power indicator goes off and the amplifier stops operating.
?When a speaker wire may be short-circuited.?When a speaker output contacts ground.
?When the unit malfunctions and a DC signal is sent to the speaker output.
?When the internal temperature is high and unit won’t operate.
?When a ground wire of the center unit (cassette receiver, CD receiver, etc.) or this unit is not
connected to a metal part serving as an electrical ground passing electricity to the battery's negative -terminal.
