Tek Posted September 15, 2010 Report Share Posted September 15, 2010 I was lookin at the 1600 watt hifonics brutus amp. I am lookin to run it at 2 ohms. It has 2 70a fuses on it, and it said 4g power wire is reccommended. My issues: isnt that much amperage too much for 4ga? I cant even find a 140a fuse can anyone clarify this for me?

Robert8252 Posted September 15, 2010 Report Share Posted September 15, 2010 (edited) Wire is fused to protect the wire from catching fire. Your wire should have a amp rating for it. Obviously you don't need to fuse it any bigger then what your pulling through your amp but if the amp has its own fuse it is suppose to protect itself so you just have to worry about protecting the wire.

Robert8252 Posted September 15, 2010 Report Share Posted September 15, 2010 I'm not positive but 4g should be rated a little higher I THINK. Somewhere recently there was a thread with most common specs on wire. Maybe look through the electrical subforum and see what you find.

7jezuz7 Posted September 15, 2010 Report Share Posted September 15, 2010 (edited) The CCA Knuwire is rated at 100 amps, and the OFC is rated at 150 amps (so get a 150 amp fuse). And I think it's about the same price as 1/0 CCA... I'm pretty sure the OFC Knuwire is more than enough, the fuse will protect the wire and provide the current the amp needs.

Tek Posted September 15, 2010 Author Report Share Posted September 15, 2010 So the wire fuse rating is based on the wire, not the amp fuse rating? Quote Link to comment Share on other sites More sharing options...
