I am assuming you are building a carputer? In this case you would need something to handle the amperage; those wouldnt last more than a few seconds, either way. You would run a single power line to the battery. If it is going to handle all you power needs, 8 guage wire is a minimum... 4 is what I hear most people using now. I used 8 back in the day for a 300 watt audio system and it was fine, with a 20A fuse. It didnt last but ten minutes with a 15A fuse. I went through three 15A fuses. Im still a n00b, dont be discouraged.
