well ive already had that planned with the electrical upgrade. cause im running an optima red top as a starter and im gonna run 2 or 3 yellow tops one for the mids and highs one for the subs and another for my bags and gonna do the big 3 upgrade along with a 230 amp alternator i believe. im just tryin to figure which would be a better choice for me. and i no that if a box isnt built right then it can make it sound like chit. but im not gonna make the box theres a guy in town that does really good on boxes
