A single 12/15 from Sundown Audio (SA), or Obsidian Audio (OA) or any of the mentioned brands will hit louder than any of those options you listed. You may be skeptical, but take my word. I was in the same boat as you, I was close to buying 2 kenwood 12's in a **** box, then I came on here and these guys turned my world upside down, and now I have a single 15 on 600 watts that gets louder than almost any 2 12' setup that my friends run, and thats in a bad box, not to mention that it sounds amazing, I can play any song and my sub won't bottom out, unlike the kenwoods, which I heard bottom out from one of my lower songs.
You came to the right place! Just take the advice, trust me, these guys know there **** //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Spend a little more money, and then you'll make your friends jealous as you bump louder with your single 12 than their setups //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Its what I do //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
