Battery Relocation Problems

[ms!3]

Shit is pissing me off. Maybe my setup is completely wrong, I'm not sure. Anyways I've been having problems with my battery ever since i moved it to the back of the car.

It wont stop popping fuses. I'm using a 100amp inline fuse about a foot away from the battery. And it only pops during startup.

Now I am using 4g wire, I know your supposed to use 2g or lower but, could this really be the problem? Ive seen so many people run 4g and be fine.

Sometimes its fine, starts up just like the battery was up front. I don't know what the hell is going on. Last night I popped a 100amp, all I had left was a 40amp, so I got some friends to help me push start it using the 40 amp and it was fine. Drove all the way home with it, kinda leads me to believe i just need a bigger fuse for startup, because it was fine with a 40amp driving home.

So I'm hoping I just need a bigger fuse? Maybe 150 or 200amp, or just 2g wire?

Now if your reading this wondering, "What the hell is wrong with this dude, is he fucking retarded?" My response would be, yes, I am fucking retarded when it comes to electrical systems and i need some help. lol

Here are some pictures of my setup.



Take note, this has always been wrapped, just showing you how I have it put together.
