I recently acquired a 2000 Watt Inverter with a 4000 Watt Peak from a friend who did not like they way it worked in his RV. How would I safely wire it into my car? If it helps I drive a 2005 Nissan Sentra SE-R Spec V. I have a single battery under the hood.
So far my plan was to mount the inverter in the trunk and run 4 gauge cables from the battery to it. For convince I was planning on wiring a switch in the dashboard with a 200 amp relay (https://www.amazon.com/dp/B01I9CI3VS). Would this be a safe option to shut it off when I am not using it? I do plan on putting a 200 amp fuse close to the battery.
In the front of the car I was looking at running an extension cable and cutting the ends and splitting the power to a few of these (https://www.amazon.com/dp/B0031C11DY). Is this the best way to do this or is there something better I can do?
Also my car is around 14 feet in length so I am imagining I will be using around that much in wire. Will 4 gauge be safe enough or will I need to use 2 gauge? I am somewhat new to this and do not want to set my car on fire.
