Is 18g pure copper wire enough for a 1000rms sub?

[Joshdashef]

I'd say 10 gauge so you can re-use the wire if you upgrade subs/amp. 12 ga if you have no plans to upgrade. If you have to wire down with multiple subs you're gonna want a smaller ga wire like 12 ga  - but even then you might need to trim some off to fit two strands in 'er. If you wanna say fuck it put some 8 ga wire and laugh at those who use it for their power runs ??

if you can fit 10ga use it. 12 should work since you splitting all that power over four runs of wire.

8.  swap it out for 8 guage.

I got 2 subs and they need to be wired up together. 8g will be too big. 12 maybe..if not 14g. That should be ok i believe

[bmwking]

if the push terminals are rated for up to 8g, use 10g to connect them together and to run to the amp output/terminal cup.  do it right the first time, dont worry about it the next time.

Math:

square root of (2000W * 1.5 ohms) = 54.8 volts

2000W / 54.8 volts = 36.5 amps

Refer to wire gauge chart: 

 

For 36.5 amps, you need 10 gauge wire for lengths 0-4 feet. So nope, 18 gauge is not good enough.

EDIT: Oops it two subs, so half that current will go to each. Still need at least 12 gauge though.

I mean I said 12ga already, but nice evidence to back it up. 

[deathcards]

12ga. or 14ga. of certain brands
