PLANNING & INSTALLING
All cables create interference. The power cable and RCA cable are
very prone to interference; the remote cables are less prone. There
is often interference caused by the alternator or other car electronic
parts. Most of these problems can be eliminated by correct and
careful cabling. In doing so, here are some following tips:
• Use only shielded audio cable for the wiring between source unit
to amplifier.
• Lay the RCA, speaker and power cables separately from other
cables with enough distance from one another. If this is not
possible, you can lay the power and remote cable together. RCA
and speaker cables should be as far away from power cables as
possible.
• Avoid ground loops by laying the ground wiring of all components
to a center point in a star-like way. You can find the best central
point by measuring the voltage directly at the battery. Now
compare this voltage value with the chosen ground point and
the (+) terminal of the amplifier. If measured voltage is only
slightly different, you’ve found a good ground point. Otherwise
you have to look for another point.
• If there are humming noises, use thicker ground cables or add
further ground cables to the chassis.
• To reduce contact resistance and loose contacts please solder
the cable ends or use spade terminals that are free of corrosion
and have the lowest contact resistance.
NOTE: The addition of a ground wire from the battery to the chassis
of the vehicle improves the performance of the power supplied to
the amplifier. This is recommended because the current delivery
of the factory electrical system was designed only to accommodate
electronics supplied by the manufacturer.
WARNING!
* Use the specified amperage fuse. Use of a higher amperage fuse
may cause serious damage.
* Using the correct gauge power wire is imperative to the
performance of the amplifier. Using power wire that CAN
NOT deliver enough current can cause the amplifier to go into
protection mode or damage the amplifier or vehicle.
* DO NOT attempt to connect a loudspeaker below the ohm load
rated on the amplifier. Damage may occur to the amplifier or
loudspeaker.
