ISO harness connection
The GZDSP 4.60ISO will be connected directly to the wiring of the factory or after market head unit (power and
speaker cables) by integrating the included ISO harness as shown below. Cars with other than ISO connectors (e.g.
Quadlock) require an optional adapter available at your car audio dealer.
Note about the vehicle´s ISO plug pinout
Please note, that the pinout of the car specific ISO plug may vary in some cases. Amongst some others the cars of the
VAG group (VW, Audi, Seat, Skoda) the pins for constant and accessory power are inverted. This has to be noticed
previous to the installation of the GZDSP 4.60ISO. For this reason, the according wires (blue and yellow) can be
repositioned at the ISO harness (see above / chapter ISO harness connection).
Please note that the GZDSP 4.60ISO cannot be used in vehicles with a factory active system installed. That might lead
to serious defects of the amplifier as well as of the vehicle´s electronic system. In case of uncertainty contact your car
audio dealer or the car´s manufacturer.
