How many woofers per box?
What amp are you using?
No special wiring necessary to parallel wire 2 boxes, of course that would present a 1ohm load to whatever amp this is connected to so good luck with that.how I would have to wire the speak on connections internally to the driver, as to make the subwoofer able to be wired in parallel to another similary wired sub.
Yes it is relevant. We need to know how many woofers are in a cabinet, how many cabinets are connected to the amplifier and what amplifier it is. We need to know the amplifier model to determine what load it can handle.I am planning to use 4 woofers, but again.. not relevant. I want to have the option to wire them in series or parallel. I dont need or want to go into the specifics of picking the correct amps and drivers.

Connecting the 2 boxes in series on the other hand would present a 4 ohm load, for that you need a custom wired splitter box that connects from the 1- terminal of one box to the +1 terminal on the other box. This also allows for the use of standard speakon cables, you could also do this with a custom speakon Y cable contraption but it's gonna be ugly to assemble if you need to use wire of any size.
On all of my self-built PA speakers there are two speakons wired in parallel, so I can daisy chain them. I believe it's much standard on non powered speakers.
So on the amp You have 2 speakons one for L & one for R.
On the speakers You have two, In & Out wired in parallel.
In Pa amps normally terminals 1+ & 1- are used, but there are also amps which use terminals 2 for the other channel or wire the 2+ in parallel with 1- for bridging.
One way is to build a splitter box for series connection, one speakon in, two out in series, clearly labelled.
For parallel daisy chain the drivers (ie you need at least one driver to have two speakons).
For series connect up the box.
If you want to integrate into a cabinet a large DPDT high current switch might be simpler option. Upto about 25A DPDT switches aren't too crazy in price(*), and never switch under high load. Switch is much less confusing to deal with.
