Has anyone changed out both terminals? I'm looking for a nice set that has two 4 guage outputs on each terminal. The negative side is easy, but the positive side has that funky connector on it. I haven't taken a real close look at it yet because it's freezing cold here, but any pointers would be great

 

Just a thought ... put in an Optima and install the new terminals on the side posts?

 

optima, sides and tops...
