how do i properly wire a second battery?
 

i want to add a second battery to my system. how do i properly wire the second battery? i think i have to wire the positive from the hood to the positve to the amp and the negative of the second battery to ground? do i wire it like i would wire a capacitor? i tried wiring it up the opposite way and blew a capacitor and caught on fire.

Wire it in parallel (pos=pos, neg=neg). How much of a system are you running that you would need a second battery?
