What needed for 2nd battery?

[The Squeaky Wheel]

Was just talking about this over the weekend! Wish there was a sticky for us that dont have the experience on what we need and more of a how to, so we can make sure we set up the audio and second battery correctly!! We all know that the stealerships charge an arm and a leg to do this stuff!!

Good idea - A sticky or FAQ would be great.

Stealerships...funny stuff - and TRUE !
