Relocating the battery to the trunk

ok, well...i've read all about relocating it's cons and pros...and i've decided i need to since i have to because of the intake


anyways....what kind of cable for the (+) should i use? meaning AWG...
also, can i just run the (+) to the trunk and then run the (-) as close as possible to the battery into a GROUND???


i know about fuses, disconnects and everything in between....just need the AWG and if i have to run two cables


oh and also ..where do i connect it to? directly into the started?


thnx in advance

Do it as if you were installing an amp
