his set-up is ported, and loud as hell but sounds horrible. I think he said it's a 10 cube box, in a extended cab chevy stepside. impressive spl though, tons of flex even with doors open. I realize I won't have the volume he does but want to keep it sounding clean. Would you recommend the bp option on a Q in a sealed box with 1400 watts? It would be rare that I would send that much to it but you never know
