Hey I have tried to search for this, but doenst look like any topic answers this question. Ok so here is goes (sorry for hte long post already)
My uncle and I have been arguing about how to fuse your system. He tells me to fuse for the equipment and I tell him to fuse for the wire. I even sent him to bcae and he still is arguing. He tells me this: "If you put that 150A at the battery with 1/0 wire, and your load is only ~80A (2 amps at 50 and 30 + headunit + relay) you will burn up everything else long before the wire goes and the equipment down the line" He thinks that I should be a 80A fuse at the battery which has 1/0 wire coming out of it. Is there a problem with this, say with UNDER fusing (bcae says the MAX fuse is something like 400A for 1/0 wire)? What will happen if I put that 80A fuse at the battery instead of 150A? Does limiting your fuse in thsi case limit your amp's performance?
Any help is greatly appreciated.Thanks in advance!
