Suitable wiring for amp?

[Briceyboy96]

I currently have an auto tek mono amp which gives the following RMS power ratings

• RMS Power Rating:
  • 4 ohms: 313 watts x 1 chan.
  • 2 ohms: 625 watts x 1 chan.
  • 1 ohm: 1250 watts x 1 chan.

I also have a 2 ohm dvc 15” subwoofer ready to go that is currently wired down to 1ohm. My wiring is already ran from my previous setup and is 4 gauge.

my question is:

Would 4 gauge wiring be sufficient for 1250 watts into the sub or is it possible to allow the sub and amp to run at 2ohms? I know wiring in series would give the amp 4 ohms but the sub wouldn’t see enough power in that case.

Thanks!

I'd be confident in 4g at 1250w, but heavier wire will always give better results. What's the sub rated for? Are you maxing out your amp?

depends on the length.....15-20ft you should be fine, anything longer you prolly want to upgrade

I don't think Autotek amps will make half rated power these days, #4 cable should be fine.

Subs rated at 1000 watts into 2 ohms, so 25% headroom

Ah okay, the guy who sold the set up told me that the wiring would catch fire if I tried it, he used to run 0guage

Wicked, thank you!

I used to power a kicker zx1500.1 on 4g wire. Never had a fire. Like I said, bigger is always better, but you're not going to die.

Makes sense, surely that’s what fuses are for anyway?

What is the fuse rating of the amp? Or model number of the amp.

Ah there we go, so the guy telling new it would catch fire was fairly clueless then?
