Best sub size

[Phoenyx]

It really depends on what kind of music you listen to, and how much you wanna spend. If all you listen to is rock or country, 10s are fine. But if it's that hip hop stuff bigger is usually better. I have always liked 15s for rap (don't tell anyone I just admitted to listening to that lol). But if you listen to a variety of music, I recommend 12s.

But all I have now is 2 6x9s. They pound my GnR good enough (for now).
