Alright I'm stumped someone help

Alright I gotta psi platform 1 10" I bought this sub for temp bass and to beat the hell out of.. It's a dual 1 wired to 2 ohms on my arc ks1200.1 (1200rms @ 2 ohms).

It's in a 4th order band pass tuned to about 52. Loud enough for the wow factor.. At first when the sub started to loosen up a bit it bottomed out a few times nothing crazy. The subs gotten scorching hot plenty of times, still played like a champ.

The other day I got in my car and it just didn't seem as loud, so I went through everything, all wires are secure and snug, all the coils read perfectly the RCA voltage is the same on both L&R RCA.

The only thing I notice is that the sub gets smelly more easily, I expected a coil reading to be off or something, but they are perfect.

SO SMELLY MORE EASILY, AND NOT AS LOUD AS IT USED TO BE, WHEN IT WAS LOUDER IT WOULDNT GET SMELLY AT ALL!!!

And get this... Each coil is reading about 1.5-1.6 the test leads have about .7-.8 resistance. When I check the wires in series I'm getting 1.8 ohms should be way over 2 ohms

Sounds like a coil issue. Might wanna pull the sub and visually inspect the coil

It didn't look bad far from black.. I've never had an issue like it

You've gotten it scorching hot and you've bottomed it out and yet you're wondering why there is something wrong with it?

Sounds like a burnt or getting burnt coil....

Yeah man... Agree here with everyone. Coil issue coming up.

Oh like I said fellas if it's a coil issue I don't doubt it..

But no lol I said it bottomed out one time when it first loosened up. Months ago. But it was playing just fine. But yeah weird fellas not a clue. It's like the amp is only seeing one coil or something

**** shoulda tried and wired them in parallel and see what it says.. I'll be back haha

No, you said

That is not one time.

Alright it goes from 1.4 (.7 ohm) to 1.2(.5 ohm) .7 off with the test leads.. But it is a dual 1 woofer so .5 is correct

So... If sub is reading correct resistance then what about the amp? And don't let the sub off the hook yet. It could still read what it's supposed to and have issues. Bottoming out once or multiple times isn't good but depending on brand of sub may lot hurt it too bad.

That's the thing it reads .5 ohm when wired in parallel like it should.. But doesn't read 2 ohms like it should in series..
