Well im getting confused. First I hear dual 1's can only be wired to .5, and 2 ohms. Then I hear they can only be wired to .25, 1 and 4 ohms. Which is correct?!?!?!

1 woofer can be wired either .5 or 2 ohms.   2 woofers can be wired at .25, 1 or 4 ohms.

Study the examples on that page to get an understanding of the available wiring configurations. Once you understand the math, it'll be easy to you. You may also want to play with these calculators: https://www.the12volt.com/caraudio/boxcalcs.asp#par

I just updated the woofer wiring wizard to include 1 ohm DVC configurations. Enjoy ;)https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=12

I did not include any 1/4 ohm configurations.

lol... I wouldn't be surprised if someone chimes in with one, but I won't hold my breath. I just added a couple more  configurations under 1 ohm just in case someone wants to play "uniboomer" with their some of their stuff ;)
