FUSION amplifiers should be connected directly to the 12V battery terminal with an inline fuse or
circuit breaker as close to the battery as possible.
Ground
When grounding/earthing your amplifier ensure that the location is a good source of ground
(preferably the floor pan). Make sure the metal is clean of paint etc, as a poor earth could
damage your audio system.
