RCA Dummy Plugs, KX-200.4, Shorting Plugs

The use of twisted pair interconnects is recommended for all installations to minimize noise. When routing these cables through the automobile, try to keep them away from factory wiring harnesses and other power wiring. If you need to cross any of this wiring do so at a 90 degree angle to reduce the potential of noise problems.

When working with power connections it is always recommended that you disconnect the battery to prevent accidents.

The ground should be connected to the amplifier first before making any of the other connections. This wire should be as short as possible (24 inches or less) and connected to a paint/corrosion free solid metal area of the car’s chassis. Use the same gauge wire as recommended for the amplifier’s power connection to the battery. Adding an additional ground wire between the car battery’s negative post and the car

chassis of this same gauge (or larger) is also recommended.

RCA Dummy Plugs

When using both sets of High Level inputs, RCA dummy plugs must be inserted into the AMP 2 inputs in order for the fader to work properly. If the amplifier is being used in any other configuration do not use the RCA dummy plugs! If you do not have dummy plugs available, simply using raw RCA ends or cutting the ends off of existing cables will be sufficient. See the Amplifier Technical manual for more information. DO NOT USE

SHORTING PLUGS!

Installation

If you ever need to remove the amp from the vehicle after it has been installed, the ground wire should be the last wire disconnected from the amplifier, just the opposite as when you installed it.

A fuse must be installed within 18 inches of the battery to protect the power wire feeding your amplifier. This fuse should be of at least the same value used in the amplifier but no higher than the capacity of the wire. See the chart below for wire size and fusing recommendations.
