Fuse to the batt from the alternator needs to be 300amp fuse.

I dont use a fuse from my alt to batt.

Why not? for $30 it's a risk that I wouldnt ever take.. I'm not even trying to sound like a ****, but WHY would you cut costs on a fuse and a holder? That doesnt make sense to me.. I'm just curious bro.

no need to. I have fuses between the front and rear batts and fuses between the amp and rear batts. besides, stock alt doesnt have a fuse so why would I need one?
