Just don't see how it happened.

He has a brand new Taramps HD 8k wired to them. First time he's powered up the amp.

I'm wondering if somehow it caused it to short the coils. But I don't see how it would short just one coil per sub.

if hey worked he apparently did something wrong. did you test the coil before sale?

Yes, I and 3 people I know...know the coils were good. I didn't however test the coil with the guy who bought it. Dumb mistake.

I still think something is up with the new Taramps he got. First run with it too.

for a coil to dead short it much be the inside coil sorting to the former.. possible it was the amp. ESP if they tested fine..

That's what I mean.. if the amp sent a bad signal it *could* cause the coil to essentially weld itself to the former, right?

I've seen amps put out a DC signal. only way to tell is put a multi-meter on the amp and see whats going on..

would a dmm work or need an oscope to do it?

if dmm, can you explain the process?

Sounds very strange to me, I've blown up a lot of subs and never saw a coil turn into a dead short.
That said, if a coil was a dead short when he hooked them up his amp would have protected or blown instantly when he tried to power it up. Feels to me like something is missing from this story.

The amp never went into protect either. It just stopped playing. We have a group chat going with the taramps dealer he got the amp from because the amp should have protected. It played fine for 30ish seconds and he was slowly turning the volume up and boom no sound.

Pulled sub's and sent me a pick of the coils on dmm. Dead short. I've never seen that unless a tinsel was torn. And both are visually perfect. No signs of issues anywhere.
