Wiring subs inside box or outside?

Hello people.

I have 2ea. DVC subs that are 4ohm and have the option to wire them in 4ohm or 1ohm.  I can wire the subs inside the box having sub1 through the dividing wall to sub2 and exiting the box.  The problem with this is I have to choose which impedance before I seal everything off.

Are there any pitfalls to wiring each sub seperately having two pairs of POS+ and NEG- exiting the rear wall of the box to a terminal strip leaving the options open to be able to switch between 4ohm or 1ohm outside the enclosure?

I ask this since I am unsure how much bass will be produced if wired to 1ohm.  I had it wired to 4ohm in my old box and it sounded pretty good.  It is because I just made a box that is a little larger and am hesitant between which impedance to use.

Any comments/ideas?

Wiring on the outside of the box would require the use of double terminals.  You can get a terminal cup with dual connections, and then label them for the different wiring schemes.  The drawback is that you have the weak terminal cup as a part of your enclosure wall.  You can get around this possible leak source by applying a heavy layer of caulk over the inside of the cup after the subs have been soldered to it.

Using wires without the cup:  you'll have a messier setup and the possiblility of erroneous connections later down the road if the wire labels become unreadable or are torn off.

I'm not terribly fond of terminal cups.  I would exit each seperate compartment with POS+ and NEG- directly through seperate tight holes and seal with silicone.

Yes it would be a two sided terminal strip using appropriate jumper wiring to achieve 1ohm or 4ohm total impedance.

Are there any cons as far as conductivity or power loss when splicing wires and then using a terminal strip as opposed to direct speaker to amplifier wiring?

Thanks for the help.
