 This unit is designed for use in a car having a 12 V 

negative ground battery system. 

 Be sure to insulate any exposed wires to prevent short 

circuiting with the car chassis. Bundle all cables, and 
prevent cable terminals from touching any metal parts. 

 Note that if your car has a driving computer or a 

navigation computer, disconnecting the cable from the 
battery may clear the memory. 

 Run the cords avoiding the spots where the 

temperature can be extremely high. 

 Continuous use of a system that exceeds the maximum 

permissible input levels may damage the speakers. 

 Since the power amplifi er has a very large output, the 

unit should be installed in the trunk of your car. 

 Do not install this unit under a carpet, otherwise the 

unit may fail because of immature heat dissipation.



 Follow an expert’s instruction for the use of the cord 

separately sold.

 For the power, make sure to use the battery lead (yellow) 

separately sold and specially designed for Panasonic 
car-audio/AV system, and to connect directly to the car 
battery. Use the cord having the fuse capacity larger 
than that of this unit. Connect the power cord and other 
cords corresponding to the power supply after all the 
connections to the speaker are completed.

 Keep the battery lead (yellow) away from the speaker 

cord.

 Make sure to use the ground lead (black) separately 

sold and specially designed for car audio system, and 
to connect it to the metal portion of the car chassis.

 Wire the battery lead (yellow), the ground lead (black), 

the speaker cords, and this unit with as much distance 
as possible from the antenna, the antenna cords and 
the car stereo (car radio).

 If the ground wire is common to both left/right and 

front/rear speaker wirings, this unit cannot be used. 
Always use the independent lead wire for the speakers 
to be used. In this case, redo the wiring.



 The speaker cords and the power amplifi er unit should 

be kept away from the antenna and antenna extension 
cord. 

 Do not directly ground the speaker cords; do not share 

the negative leads of multiple speakers. 

 When using the RCA cords, keep away from the 

speaker cords. 



 Use speakers with a suitable maximum input. 
 In case of 4-channel/3-channel connection 

  Use speakers with the impedance of 2

8 .

 In case of 2-channel/stereo connection:
  Use speakers with the impedance of 4

8 .

This terminal cover is for preventing short-circuit between adjacent terminals. Before connecting each lead, pass it through 
the terminal cover. After connecting the leads to the terminals, cover the speaker output terminals and power terminals 
with this cover. Make sure that the projections to prevent slipping out are facing down.

For power connection, use the optional battery lead 
(yellow) specially designed for car-audio system and 
connect it directly to the car battery.  
Use the cord having the fuse capacity larger than that of 
this unit. 
Securely tighten each lead with a terminal screw.
1  Unscrew the terminal screw.
2  Insert the screw into the terminal of the lead. Securely 

fasten the screw.

If the battery lead has to be routed through high 
temperature area, protect it with a corrugated tube 
(option).
