Tune it to 35hz and OUCH! Yes, it will definitely be LOUD! You could probably actually tune to 30hz, get a little better low end, and still be painly LOUD!
You're gonna need a BIIIIIG box!! I'd rather have one 15" l7 in a biiig box than 3 in boxes that are too small, but if you've got the room to do a big box, it'll be awesome.
whats this going in? a cargo can or tahoe or something? Thats a lot of space, still dont understand why people would even want 3 15s...just seems pointless to me.
Anyhow, gl with the install.
Ya shouldnt need 3 15s for loud and deep bass //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.
