i have 4 dual 4ohm speakers in a fiberglass box. they all share the the same airspace no dividers. I have the wiring diagram to get a 2 ohm load but i want to invert 2 of them. how do i wire them because i know you have to wire the inverted ones differently then the regular mounted ones. any help would be WONDERFUL thanks!

You must wire the inverted speakers out of phase with the conventionally mounted ones. On the inverted ones, treat the negative terminals as positive, and treat the positive terminals as negative.

im doing the series/paralell so all i do is the normal pos. to neg. on the speaker, then treat the pos as neg and neg as pos to the next speaker?

You say to the next speaker, that is only correct if the next speaker is the one mounted to the front of that speaker. All speakers mounted to the box in the conventional manner are wired as they are labeled. If the speaker is inverted, connect the positive wire to the negative terminal of that speaker. Connect the negative wire to the positive terminal of that speaker.
