i re-located my battery to my trunk to make room for charge pipe and put my yellow top in there, but i got staight 4gauge to the batt from my dist. block under the hood. i've been told i should use a fuse or circuit breaker by the battery which just kinda makes sense anyways

what size fuse or circuit breaker should i use? im assuming engine cranking would blow most of the car audio fuses i have around (30A-60A), and i'd rather just get a breaker incase a fuse would blow and i dont have another on me.

 

I don't think 4 gauge is heavy enough... Does it crank ok or a little slow?

 

it cranks normal. actually a little faster with the optima

 

4 gauge is prolly enuff cause thats wut ive been using for a while now

 

so can anyone answer my question?

 

On mine i am using a 100a and have had no problems.

its a fuse block like this one
