plastic melted off speaker wire?

[HatersGonnaHate]

Use the biggest gauge wire that will fit in the sub terminals. But yea, I'm with everyone else, wires were too small, and the current going through them heated it up.

[Exploader1]

well The wire did fall off so maybe in the process it got to the tip of the clip and heated up that plus it's small wire

I use 12g on my front speakers and 10g on my sub. If you're running 2000w at 14v you're able to run a max of 140A through your speaker wire. For that you need like 4AWG wire, but you're not running full-tilt all the time.

O really?

Show me how you calculated the 140amps.

Spoiler: Jaloosk don't read this before answering. This is how you actually calculate it.

2000W at 1 ohm= 44.72V x 44.72 A

But that's 44.72V RMS, the rail voltage will be 63.24V and the amperage will be 31,62A.(but this calculation has nothing to do with the power going thru the speaker wire.)

So the most amperage the 14g wire will see on a 0db test tone at 1 ohm without any "rise" is 44A.

ANd if he plays music which is dynamic it will be closer to 20A and because the ohmage of the sub changes with each frequency, the wire will barely see a constant 10-15A.

EDIT: 14guage wire has a capacity of 15-25amps depending on circumstances.

So the wire itself isn't the problem, it was probably not connected good enough.

HOLY SHIT hahaha damn you know your stuff

You just blew my mind

2000w/14.4v = 138.8A I know it's not exact, but I always thought it was a good guideline. FWIW, according to the american wire gauge table 14AWG cable can only safely support up to 32A...what source do you use for gauge capacity? I'm using this: http://www.powerstre...m/Wire_Size.htm If there's something better for car audio applications, I'd be interested in it!

Ur talking about power wire. The wire in question is speaker wire

[Jaloosk]

What's the difference? A 14AWG cable is a 14AWG cable. "Speaker" cables carry power just like "power" cables. It's electricity that's driving the speaker, after all.

The difference is 138 amps to 40 something amps at most. There's no way a 2000 Watt amp is ever gonna push 138 amps through the speaker wire. And according to what u said his wire was sufficient for that amp load when it obviously wasn't. _

Amps boost your battery voltage so you don't divide the 2000w by 14v...

You need to know the level of the internal voltage rails.
