im looking into the skar audio vvx8's and i wantt to know what box would give better sound. i listen to mainly rock, metal,oldies and even a lil biyt of classical. i listen to rap too but only in my blaazer. so for these subs, what would sound best ported or sealed and does anyone know what the cubes are. i believe its similar to the sa8's and only .7 cubes each. if ported, how should i port? aero port or?
