For multiple amplifi er installations where distribution blocks are used, each amplifi er should have its
proper-rated fuse, or breaker, installed between the amplifi er and the distribution block within eighteen
inches of the block, or on the distribution block if it provides for fusing. The primary power wire should
also be fused between the battery and distribution block, within eighteen inches of the battery's positive
terminal, with a fuse or breaker rated at least to the sum of the individual amplifi er's fuse values, but
doesn't exceed the capacity of your wiring.
