optima yellow top

please help

ported and vented boxes are the same thing. The types of ports are different though, circular ports...square ports....slot ports. As for that, u need someone with winisd! I don't have it, b/c i'm at school...o sorry can't help ya here. AND, as for the optima yellow top, are u just adding that extra battery? Are you doing anything to your alternator...or keeping stock alternator? If so, don't ge the extra battery. peace
