Started making a booster cable hookup for my car. That was the worst part about having to get jumped or help someone jump their car is taking out the sub box to do it. Also making my own set of booster cables. KnuKonceptz.com is the cat's pajamas by the way.
Where are you putting yours?
I felt the same way when I battery was bad and I had to get jumped every other day. I got a new battery but I still ended up putting one on the right side of the trunk, right below the trunk arm. It's pretty hidden and has a red post cover. For ground, I sanded down the little hook right next to the trunk light , about 10" away from the + post, very convenient.
