Not being an audio or electronics kinda guy, I'm asking for a bit of help on how the two drivers in the WO-32 should be wired together.  I'm going to be using single voice coil (SVC) style drivers, either 4 ohm or 8 ohm -- not yet decided which ones just yet.  If I choose a pair of 8 ohm SVC drivers, should they be wired in parallel to yield an overall 4 ohm impedance to the amp?  Conversely, if I choose a pair of 4 ohm SVC drivers, should they be wired in series to yield an overall 8 ohm impedance?  I will be using the Dayton-Audio SPA250 plate amp.  Thanks for the help.
