I’m setting up a system in my jeep,and I have a 300/4 running my highs,but i wanted to know what kind of power protection do i need for the 1000/1 amp?I’m running just one 13w7 with an alpine head unit.
Use this guide to determine what size power/ground cables you’ll need for your amp(s).
Add the fuse sizes on the amps together (ie: 25 + 50 = 75amps) and find out how long you’ll need it to be.

What ever size wire you use, put a fuse within 18" of the battery. *If you have a battery in the trunk as well, put a fuse within 18" of that one also.
4g wire goes up to 150amps (you’d use 150amp fuses). 2g 250amps (250amp fuses), etc.
Good Luck!
