I 100% believe you. I don't think you may have done anything wrong. Like I said, you have an amp that can produce a 3Kw sine wave, and other waveforms up to possibly 6Kw... What normally happens is the lead fails in one spot and heat begins to build, it just gets worst from there... It can be a failure from the way the leads were sewn in/installed to a bad lead material, to over excursion of the sub to simply too much power. It just happens. All I am trying to get you to do is look objectively at your situation, and cut through the BS... Everything can be explained through simple circuit analysis, it isn't Voodoo, although some people would have you believe it...

This isn't anything new. The same principles apply to power/isolation transformers. The main reason all the RF/EMI garbage (like the unfiltered Class D components) doesn't make it through a power/isolation transformer (like the woofer's voice coil) is due to the inductive component presenting high impedance to the unwanted signals. The high impedance doesn't let the current flow and therefor the signal make it through the transformer (voice coil). It also doesn't matter if it is a sine wave or some other type of signal, even pulses or a square wave, it has to do with how the inductance simply won't let the current flow...

I have no doubt the unfiltered HF garbage coming out of a class D amp causes issues, mostly distortion... But in a series circuit that has an inductor (voice coil) with any appreciable amount of inductance anywhere in the circuit, there won't be significant current flow (in the HF range) and therefore heat. Even if the HF is lower, even in the audio spectrum, it will have an insignificant amount of power compared to the intended output of the amplifier...

It has nothing to do with clipping. It has nothing to do with filtering either, the inductance of the voice coil prevents the higher frequencies from ever causing enough current flow to actually heat the leads. Don't believe me? Calculate the current flow through a 3-4 mh inductor (the voice coil) at the switching frequency of the amp at the maximum rail voltage... It is no more than a few watts, that doesn't heat up crap... (an amp that switches at 250K will see a load of 4.7Kohms into a 3mh voice coil at that frequency, this will equal 2 watts if the amplifier put that out at 100 VAC..., harmonics will be even lower) Hopefully this put the whole "microwave the leads" myth to rest... It has to do with the lead in your case having a failure in one place and the current is forced to flow through less effective cross-sectional area of conductor, increasing heat. As heat increases voltage drop and heat increases. It just keeps getting worse. You have a 3Kw amp, that is what burned up the leads...

In no way you can compare my amp to an ap3kYou should spend more time thinking about my second statement than getting butthurt assuming im comparing your amp to an ap3k. once again DIRTY POWER DOES BAD THINGS.

TrueNutrition.com, why must you tempt me with your cheap wares?!?!

I agree 100%. Thanks for the minus 1 asshat.

nnnnnooooo if i would of known i would of bought it strapped it to my bc2000d.
