What's funny jrich, is that you never even say what ohm's law is. V=IR, and second, take a look at a speaker's sensitivity (effenciency rating) at crutchfield.com. While a speaker may sound louder with a higher sensitivity, it won't neccessarily sound better. Get some Alpine speakers.
Also, rcurley55 doesn't defy physics. Wake up jrich and learn to read and write properly. Maybe you need some physics and english courses??
