My subs have been shipped and our on their way. My question is, what would be the correct size speaker wire to use for them. Also, the speaker wire coming out of my terminal cups seems a little on the thin side. Should I change this out too or will it matter. It's pre soldered in my pre-fabbed enclosure. For informational purposes the subs are two MOFO 10s 1000rms/2400watt peak. Plan on going with the NINe 1 amp or if they are still having problems shipping these out will be going with another amp with similar specs.
12 AWG would be fine, If you can fit 10awg it will be bulletproof. Solder is fine. Its the best connection you can make. Sounds like some nice choices in equipment. Good luck.
