Right now I'm running a icon 10 in a ported box to spec off of a aq1200d. I wanna try another set of subs and I have 2 si bm 10s laying around, my question is will those be louder, running off the aq1200d and a ported box, or will it pretty much sound the same as the icon? I was also thinking about a pair of sealed (no room for ported) 12s such as type-rs or ia 187s. Which route will be significantly louder?
