Note about the current requirement
The GZDSP 4.60ISO amplifier has been developed to be installed using the factory wiring. For some vehicles however,
it might be necessary to connect the power wires of the GZDSP 4.60ISO directly to the car´s battery and the ground
wire to the car´s body.
- The factory´s wiring of the head unit should have a fuse with a value of at least 20A. Otherwise the power
supply might be insufficient for an accurate operation of the amplifier. (see fuses / car´s owner´s manual)
- If there are further aftermarket units like a handsfree, GPS system, charging cable or similar consumers
connected to the head unit´s factory wiring, the current might exceed the fuse value.
- It is not possible to install more than one GZDSP 4.60ISO using the factory´s head unit wiring. If further
amplifiers are to be installed, the power wire has to be connected directly the battery and ground wire
directly to the car´s body.
- For the best result, it is recommended to connect the power wire of the GZDSP 4.60ISO directly to the
battery and the ground wire to the car´s body. For this, the cable connectors of the harness have to be
dispatched and connected to separate wires (not included). Please, contact your car audio installer if
necessary.
