RCA INTERCONNECT WIRING
Choose the correct length and style of RCA interconnects for your needs. The range of RCA gives you a wide
choice to suit your needs. These have multiple layers of shielding or are a twisted pair variety for better noise
rejection.
Be extra careful with your RCA interconnects. Car environments are notorious for poorly insulated wires. This
means that hiss, engine noise, and fan noise can easily be picked up through RCA cables if run incorrectly.
Make sure that the cables for power and audio signal are not on the same side of the vehicle and that they
do not cross each other; this will help reduce any noise that may radiate from the power cable and the signal
cable. If an audio cable is too close to a power cable, it may pick up the magnetic field generated by the
power cable, which could lead to a loss of quality in your signal.
If RCA interconnects must cross power cables, noise can best be avoided by crossing them
between 45° and 75°.
