Additional Information

Connecting the units

Note:

This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recre- ational vehicle, truck or bus, check the battery volt- age.

To avoid shorts in the electrical system, be sure to disconnect the battery cable before beginning installation.

Refer to the owner’s manual for details on connect- ing the power amp and other units, then make con- nections correctly.

Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around them where they lie against metal parts.

Route and secure all wiring so it cannot touch any moving parts, such as the gear shift, handbrake and seat rails. Do not route wiring in places that get hot, such as near the heater outlet. If the insulation of the wiring melts or gets torn, there is a danger of the wiring short-circuiting to the vehicle body.

Don’t pass the yellow lead through a hole into the engine compartment to connect to the battery. This will damage the lead insulation and cause a very dangerous short.

Do not shorten any leads. If you do, the protection circuit may fail to work when it should.

Never feed power to other equipment by cutting the insulation of the power supply lead of the unit and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating.

When replacing fuse, be sure to use only fuse of the rating prescribed on the fuse holder.

Since a unique BPTL circuit is employed, never wire so the speaker leads are directly grounded or the left and right speaker leads are common.

The black lead is ground. Please ground this lead separately from the ground of high-current prod- ucts such as power amps.

If you ground the products together and the ground becomes detached, there is a risk of damage to the products or fire.

If the RCA pin jack on the unit will not be used, do not remove the caps attached to the end of the con- nector.

Speakers connected to this unit must be high- power types with minimum rating of 50 W and impedance of 4 to 8 ohms. Connecting speakers with output and/or impedance values other than those noted here may result in the speakers catch- ing fire, emitting smoke, or becoming damaged.

When an external power amp is being used with this system, be sure not to connect the blue/white lead to the amp’s power terminal. Likewise, do not connect the blue lead to the power terminal of the auto-antenna. Such connection could cause exces- sive current drain and malfunction.

To prevent incorrect connection, the input side of the IP-BUS connector is blue, and the output side is black. Connect the connectors of the same

colors correctly.
