Wiring
Signal can be input into the amplifier using either the low level RCA input connections or the high level speaker level connections. Using the low level RCA connections is the preferred method. Use the high level inputs only if your head unit does not have low level RCA type outputs. Connecting to the amp with either input will provide a low level signal at the output (PAST) 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 possibility for noise problems.
When working with power connections it is always recommended that you disconnect the battery to prevent accidents.
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 highly recommended. Adding or upgrading the ground from the case of the alternator to the car chassis is also recommended.
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.
The supplied ANL fuse holder and fuse must be installed within 18 inches of the battery to protect the power wire feeding your amplifier.

Installation
The ground should be connected to the amplifier first before making any of the other connections. This wire should be as short as possible (36 inches or less) and connected to a paint and corrosion free solid metal area of the car’s chassis.
