AMPLIFIER WIRING
Power Connections
● Fuse Size: (2) 30 AMP ATC
● Minimum eight-gauge power and ground cable is recommended for acceptable
performance.
● Fuse power wire prior to wire passing through panels or near sharp edges and less
than 18" from battery.
● Ground the amplifier to a good chassis ground as close as possible to the amplifier.
● Add extra ground wire (minimum eight-gauge) between the negative terminal of
the battery and the chassis.
NOTE: The addition of a ground wire from the battery to the chassis of the vehicle
improves the ability of the battery to supply power to the amplifier. This helps
especially in newer vehicles, where the current delivery of the factory electrical
system was designed only to accommodate electronics supplied by the auto man-
ufacturer.

● Crossover mode, output, and gain configurations are independently adjustable
between the front and rear channels.
● Two-channel or four-channel input can be used for this configuration. For source
unit fading, use the four-channel input mode.
● Front and rear outputs can be configured for high-pass, low-pass, or full range
operation.
