Is 12gauge speaker wire sufficient for running a saz-1500d to sa12s. I'll be running the amp at 1ohm.

Speaker wire is about 4feet in length. If it can't handle that much power then can I just double it up and run two strands for each positive and another two for the negative.

try to fit the biggest wire you can...

12 is fine if you have nothing bigger

So assuming you are running (2) D4 subs and ~1800 watts from that amplifier, 12 ga is more than enough.

okay thanks guys, one less thing I need to buy at the moment

10-14 gauge wire will do fine for subwoofers but you can go bigger if you want to, just a preference thing thats all.

Unless you're after all out SPL, there's no gain to be had running something bigger then 12 gauge.

i'm not competing or trying to raise it a couple db's

All I have is 4 8 0 and double 0 lol. I run 8. But its really not needed just what I had at the moment.
