Do not run wiring underneath or outside the car since exposure to the elements may cause
the insulation to deteriorate rapidly, resulting in short-circuits and/or intermittent operation.
all cables should be run beneath carpets and inside trim pieces.
To help minimize interference, it is best to run the power cables along the opposite side
from the audio cables
Whenever wires pass through metal, rubber or plastic grommets must be used to prevent
the metal from wearing through the installation and causing a short.
Whenever possible, use cable ties, mounting clamps and similar wiring aids. (available
from an electrical supply or auto parts store) Adding stress relief loops to wiring is also
advisable to prevent straining or breakage.
