still have it! bump

This shit is nuts bro. nice build!

I'm basically asking if an external subsonic, HP filter, or crossover pre-amp would be a good solution to better signal output.

yes why?

you have very nice equip in your build btw. I respek dem.

made me feel a lot better too

I burned up the leads on my zcon as well. All people claim its "clipping" 98 Honda Broke it down to this: 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..."

it seems like back in the day the problem with leads was them snapping because of excursion. Now a days they are burning up because they are sandwiched or sewn. I think it had something to do with the materials it is connected to, and the amount of glue used to secure them in place.

so what addition to UF class D signals can be added to ensure the voice coil is utilized in the circuit?

good thing they make recones

could you elaborate a bit on that?

Thank you. We'll recone her and put more effort into learning about why this happened and how I can prevent it next time.

My amp only has an input sensitivity of 2.5v. The headunit is 4.8v preouts. I used a vol adjust option on my JVC headunit to +1 position. Amp never got hot, sub never got hot, just poof.

Thanks, I feel much better =]

I never posted a comparison to the coil in the woofer you sold me Bassink but since you asked for it here it is:

This recone didn't have a sewn "pouch" made for the leads like the other I had.

And this help furthers my statement......start dropping volts and start sending more dirty power to your subs....and poof I never dropped below 13.5. But that's from my rear batteries. I think using the Vol adjust on my head unit may have had something to do with it.

I wish it would have been and I would have assumed responsibility. Fact is you are a bad seller and you ripped me off. Why would you even post here.

In no way you can compare my amp to an ap3k

I guess I need an alt. like asap. Thought it could wait until spring

I use a MMATS M3000.1. I thought it might have been due to moisture getting to the sub. Bottom of the motor was a bit frosted.

So I was coming home from work yesterday and I was bumping at a decent volume. I started to smell something burning, but it wasn't coil. I took a reading of the coils from the amp today and wasn't getting the correct nominal. Took the sub out and read the coils from terminals. One coil wasn't reading out at all, and the other was reading like 12. Took the coil out and this is what I found: Recone was done in November or so. This sucks.. =[

it might be an older dreadnaut

what size?

abuse it and find out. then recone it.
