what gauge speaker wire would be recommended for 4 10" fi bl (flat wind coil, cooling) i have 12 gauge speaker wire but im thinking that that is too small. its kicker shielded wire. would i be able to tie the 2 wires together and double them up to have roughly 8 gauge wire? or is the 12 going to be enough?

What kind of power are you running?

2500rms at 2 ohms.

12 gauge is just fine

ok thats what i though. but i had heard alot of people saying that 12 is too small. would i gain anything by bigger wire? or is it quality rather then quantity?

not really

8 gauge ftw ...

lol 12 gauge will work just fine though..

im going to double up my 12 that i have now. at very least the wire inside of the box is going to be. outside will depend on how much i need in the end. i should have more then enough but you never know till you get started.

I ran 12ga with 7k just fine.
