when wiring subs to different ohm levels, does is matter what kind of speaker wire you use to connect to the + and - terminals? i mean like gauge wise of the speaker wire and such.
Too big of wire is just a waste of money. As Rick said, 12-16 is ideal for subs. 10 AWG would be the maximum size required.
i'd use the same as the rest of teh wire, and always go larger never smaller. the cost of wire for teh few feet needed in a car, seams silly to me to go cheap... most places allow you to buy it by the foot. i usually use 12 ga for subs and 16 for mains..
the larger the wire the better the current move through it, i likeusing at least a 10 gauge, im using 8 right now its also harder to get them caught some were and break them
