lol 30 bucks in 1/0 and connectors. That will be a lot more then that especially OFC which you would want to do, 1/0 connectors can cost up to 10 bucks for a 5-10 pack then the wire is another 40-50 bucks minimum in ofc because if you are going to wire it as a 1/0 big 3 then you are crazy not to run 1/0 as well back to the amplifier to get the most out of it. Also read my whole post also the GCon can handle quite a bit as well especially with the upgrades, SSA will confirm that as I emailed them myself this afternoon asking those exact questions! And don't tell me what to do either.
Exactly Buck!A dual 4 ohm sub can be wired to 8 or 2 ohms.
A dual 2 ohm sub can be wired to 4 or 1 ohm(s).
