hah hah hah... no worries.. I just look at a lot of stereo posts every day; it is easy to not remember when you were already visiting with someone on same or similar subject; want to make sure to give you good information in light of the total system...
I see. Since you have the sub on half of the amp, you only have 2-channels to run the Wetsounds with, and the only way is one speaker per channel, at 120 watts per speaker.
If you want more you have two quick options. Buy a new amp for the sub and run the ZZX650.4 in (gasp) bridge mode, (by now you should know I do not like bridging) on the Pro 80's. In that mode, the amp can deliver roughly 325 watts to each Pro 80.
The other option is to buy a dedicated amp for the Pro 80's, as TigeMike suggested. the ZX550 is probably the best one from Kicker.
It sounds like you are still in experimentation / dialing-in mode and are trying to find the ideal setup. That is for sure okay. At times it is fun; at others, frustrating. In the end, you may or may not find that the ZX650.4 has a place in your system...
Hang in there and keep at it and you will figure out what works for you, but no, in answer to the original question, there is no way to wire a single 4-ohm speaker to 2-ohms. Additionally, and I think TIm will agree, you really want more power than that on the Pro 80.
Sorry if it sounded like I was hammering on ya; again, just wanting to make sure I give you the VERY best information!
Have a GREAT weekend Tony! (seems like it should be written on a cereal box)
