what do you use to connect the power wire to the positive part on the car battery? my friends all just split the wire and put that around. but it looks very messy, hard to fasten back on since the wire's so thick under the wire you have to screw on over it. and where can i get the connector?
if it's 4AWG or smaller you can use a ring terminal on the battery post of the post binder bolt. if it's larger than 4AWG you'll want a battery post terminal that accepts large gauge wire directly with allen key screw down ports like on a distro block
