tuning my system

What the hell kinda woofers you got? Those specs are all over the board! Nominal Impedance: Dual 3 ohm Voice coil type: Single So which is it? 45Hz Fs? GAH!!! .94 cubic foot Vas? Qts of 1? Impossible, I think... (Sounds like they couldn't translate some word to "Yes", as if to say "Yes, it has a Qts".) Frequency Response: K - Hz Only 3.9 pounds of magnet? Complicance? What's that? Sound like "Dual"s... Swap-O-Rama specials. Dude, cut your losses right now, ditch those things, and get better drivers. With published "specs" like that, you'll never know what kind of box you need. I've seen PA woofers with better low frequency capabilities than those. I truly hope you didn't pay a bunch for those... Truly.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

they are kenwood kfc w3011 12' subs.

Another PERFECT example of name meaning nothing. (Either that, or Kenwood REALLY showing how crappy their products really are!) Ditch 'em. Those are completely un-trustable specifications. Sorry, but that's what I feel about those woofers. I wouldn't ever trust 'em.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I agree.  Those specs look like a bad translation from the Chinese.... Support the12volt.com

I was under the impression kenwood was one of the best,thats the only reason i bought them,where were you guys three months ago,lol, so what brand should i get ,pioneer maybe or sony xplod, give me some input as the last ones i owned were MTX blue thunders....HELP.

  haemph, that's some funny stuff.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Well, the Pioneer may or may not be better, depending on the model. Sony Xplod is on a par with what you already have, so don't go there. What is your ultimate desire, and how much you wanna spend?
