Right at your crotch I'm guessing. I only looked under there for a second. I think two in the center would work if you also had some mids/highs in the doors or kick panels. I would look at each horn differently and then decide on its placement. You can actually buy the driver (what produces the sound) and then build your own horn (disbursment mechanism) out of ABS plastic. If your running 10's and you've done it right, you'll need a ton of front end (mids and highs) to keep up.
