you need a plumbers soldering torch to get them on, and a lot of solder lol. you heat the piss out of the new end, ( in a vice) and fill it 1/2 way with solder, flux the wires, and stick the stripped end into the hot melted solder, hold it till it cools and its on for life. add shrink wrap when its real cold, any heat makes them shrink fast.
search you tube for how to solder battery cables. its the best way. and you should get some shrink wrap tubes to seal it off good and tight, anther 5 busks or so.
thats why in going pre made, it saves a few bucks in the end. you'll be up paying 10 bucks more then me in the end im sure. not like its a lot of money, im just cheap lol
but making them just the right size is nice as well.
