Wiring

Signal can be input into the amplifier using either the low level RCA input connections or the high level (speaker level) input connections. Using the low level RCA connections is the preferred method. Use the high level inputs only if your source unit does not have low level RCA type outputs. Connecting to the amp with either input connection will provide a low level signal at the output (PAST) RCA jacks.

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 alternator noise and electrical interference.

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- and 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.

If you ever need to remove the amplifier 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.
