Wire Size For Subs-quick Answer Pls.


Recommended Posts

4 ga?! as speaker wire? uh... thats gonna be a bitch to fit, and WAY overkill, its only 1000 watts

and since you are using 2 12 gauge to go from to each positive that allows for 950w, as stated, 10 if you can fit it but 12 is used in almost all applications

i like to use 2 12 gauge of equal length positive and two 12 gauge equal length negative, and twist the 2 positive into one, then into amp terminal and same for negative, it is the same as the rockford fosgate wiring diagram, 2ohm dvc to 1 ohm, if you are concerned about loss of power due to wire size, that would help alot.... and in your case of bl's, why not

I already got the 12 gauge speaker wire. Instead of splitting it up Im just going to combine the ends together...So it can carry the power of 2 12 gauge wires...

sounds like a plan. post pics bro.

Out of curiosity, would using one run of 14 gauge along with one run of the 12 work? I only ask because I already have a good amount of 14 gauge so it will save me a little. If I understand correctly, electricity follows the path of least resistance, so once the 12 gauge becomes over powered will it move over to the 14? I know this probably sounds confusing but I want to wire my subs today and don't think 15' of 12 will be enough.
