800.1 = 60A (2 x 30) I would use a 50 or 60 amp
Harpoon = 80A (2 x 40) I would use a 80A
SM600.1 = 50A (2 x 25) I would use a 40 or 50 amp
For the main circuit protection, I would use a 120A or 150A breaker or fuse. As noted, the amp's estimated current draw will depend on some variable factors such as battery level, volume and music type, but it also depends on how many chnls are running at 4 ohm and how many or running at 2 ohm. The load on the chnl dictates the amps output, thus the current draw.
Would a single 1/0 gauge input be enough for four 4 gauge outputs? Thinking about adding a fourth amp in the future.
If your running the harpoon at 2ohm would it increase the fuse rating from 80 to 160?
cool so i can use a 250 resetable breaker from the battery to the block, then match each amp rating from there on out assuming the cables are properly rated..
great info thanks.
With 12" of 1/0, you're with a 250A breaker. I think you could go with a 200A if you are going to run the 1500.1 @ 2 ohm as opposed to 1 ohm.
