Installation

Before Installation

 

Mount the unit either inside the trunk or under a 
seat.

 

Choose the mounting location carefully so 
the unit will not interfere with the normal 
movements of the driver and it will not be 
exposed to direct sunlight or hot air from the 
heater.

 

Do not install the unit under the fl oor carpet, 
where the heat dissipation from the unit will be 
considerably impaired.

 

Mount the unit as illustrated.

Screw

Ring rubber 

cushion 

Cautions

 

Before making any connections, disconnect the 
ground terminal of the car battery to avoid short 
circuits.

 

Be sure to use speakers with an adequate power 
rating. If you use small capacity speakers, they 
may be damaged.

 

Do not connect the 

3

 terminal of the speaker 

system to the car chassis, and do not connect 
the 

3

 terminal of the right speaker with that of 

the left speaker.

 

Install the input and output cords away from 
the power supply wire as running them close 
together can generate some interference noise.

 

This unit is a high powered amplifi er. Therefore, it 
may not perform to its full potential if used with 
the speaker cords supplied with the car.

 

If your car is equipped with a computer system 
for navigation or some other purpose, do not 
remove the ground wire from the car battery. If 
you disconnect the wire, the computer memory 
may be erased. To avoid short circuits when 
making connections, disconnect the + 12 V 
power supply wire until all the other wires have 
been connected.
