I am running 1/0 through my whole system and i have a 1/0 ANL fuse/holder... and right now i have a 100 amp fuse in their, but anyways, i am going to be buying the hifonics bx1500d and i am gonna be running it at 2 ohms for a while untill my current subs blow then im upgrading to two L7's and then im gonna be running the amp at 1 ohm, whut size fuse should i be running once i run it at 1 ohm, 125,150,200????
put in a fuse that is rated at an amperage right under the amplifiers needed amperage, thus protecting your wire from overdraw.
but see thats why i made this thread, becuz i dont know how much the hifonics 1500 pulls at 2 ohms, and at 1 ohms, that is whut im wondering...
You should be fine running the 100amp fuse for now. If it blows later on upgrade it, but I doubt you'll need to.
Jsut look at the fuse on the amp. How much is it?? That is how much amperage the amp is going to want to pull at peak power. This isn't rocket science. Now get a fuse that is either right underneith that number or one that matches it. Now your set.Quote:

Fuse for the limits of the power wire (guage voltage/thermal limit).
With 1 ott wire you can fuse up to: ~300 amps.
IMO, get a 200amp ANL and be quite safe (happy).
oh okay thanks... i am going to get a 200 amp fuse so that if i ever decide to get another amp i wont have to worry about the fuse... thanx for all your help!!
