how to determin speaker wire ga for RMS ?


Recommended Posts

So my sub wire is 12ga OFC sky high wire, run is less then 4 feet from box to 1500 watt amp... Just bought a twisted sounds 2.8k... With this higher output amp would i need bigger speaker wire or is 12ga enough ? My speaker terminals will accept 8ga and im gonna assume the 2.8k has 8ga outputs... Should i buy 8ga wire ? Or is 12ga OFC acceptable for this power.... Where is the "cut off" for when you need to upgrade your speaker wire ?

Do you have each sub run back to the amp individually or do you have one pair of wires used for both subs?

Nice calculator, but I wish I knew more to fill it out correctly...I know something isn't right. The results I got said I'm pushing the limits of my 8ga leads to my subs. I remember looking at a chart a while back(couple years maybe) that made me feel comfortable with 8ga wire to each of my subs with a 7500 on each. I was going to do 4ga but had figured out back then that I wasn't even close to needing it.

Just set it at 0,

For what you're wanting to know it's irrelevant anyways.

Changing that number has no impact on how much power the wire can supply.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
