Malfunction: Interferences
The cause are always the wires. Especially the power- and signal wires are vulnerable. In most of the cases the
inteferences will caused by the light generator of your car or other strong electrical devices. Avoid this by proper and
appropriate installation of all wires.
Please follow these instructions:
1. Use only shilded RCA-Wires, which are designed for Car Audio Systems.
2. Install and mount all loudspeaker, line-signal and power supply wires with a sufficient distance to each other, also
to other wires of the vehicle's electrical system. If this is not possible, install the power supply wires together with
the serial wires of the vehicle. The RCA wires should be installed with a sufficient distance to these. The remote
wire could be installed together with the RCA wires.
3. Avoid any ground loops, by installing all components with a starlike arrangement. This means every component of
your soundsystem needs a own separate ground wire.
If the malfunctions are still be on hand, consult your local Car Audio Retailer.
