Joshdashef Posted October 7, 2018 Report Share Posted October 7, 2018 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 ??

Jessica Posted October 7, 2018 Report Share Posted October 7, 2018 if you can fit 10ga use it. 12 should work since you splitting all that power over four runs of wire.

akuma4u Posted October 7, 2018 Author Report Share Posted October 7, 2018 3 hours ago, bmwking said: 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 Link to comment Share on other sites More sharing options...
bmwking Posted October 7, 2018 Report Share Posted October 7, 2018 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.

k58.cross Posted October 15, 2018 Report Share Posted October 15, 2018 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. Link to comment Share on other sites More sharing options...

Jessica Posted October 15, 2018 Report Share Posted October 15, 2018 I mean I said 12ga already, but nice evidence to back it up.
