I need some opinions on ported or sealed, the car is going to compete SPL but I also want a decent music car as well.

How many batteries also should I go with alongside optima redtop?

 

What class are you entering? What organization; dBDrag, IASCA or another organization? Have you researched higher output alternators? Do you plan on using all of the nearly 8k daily? You want to compete and you question ported or sealed? I'll give you a freebie... Ported. Have you looked into sound deadening? If you want the car to be musical, what have you decided on for full range components? What about powering them to keep pace with the low end? Many questions, my young apprentice....
