i moved the ground wire and battery to the trunk already. what gauge wire should i use? will one gauge amplifer wire work?

 

What kind of battery did you use?

It's not exactly safe to just move an acid battery to the rear of the car, it should be in a sealed battery box that vents outside the car.

 

1 gauge will work, make sure you have a fuse inline. And also a battery box that vents to outside if its not a sealed battery

 

1 gauge sucks. Use 0 gauge so you don't have to do it twice. I'm speaking from my own experience.

 

its a exide racing/commercial battery. its too big for my front battery location bc it rubs my clutch cable. I ran one gauge amp cable with a inline fuse block and so far ignition clicks over and relays click. I'm making sure the gauge bc after engine is rebuilt dont wanna burn my car down.

 

I had a crx with a relocated battery using 0 gauge wire, never had a problem with it. I would probably go that route. And x2 on the sealed or vented battery idea.
