If you Relocate the battery into the boot, where woudl you route the cables? Through the interior or under the car running alongside the exhaust channel?

Has anyone done it? or mounted it somewhere other than the boot?

i have done this cable goes throw the car seats carpet up and then in to the wheel well behind the wheel arch liner were i ran the cable in a thick rubber hose use a think high amp cable and fit a mega fuse near the battery you can see the yellow hose were the cable goes throw the box section the hose is to stop the cable rubbing in the metal here is mine
