Default rattling sound and noise from my level 5 12 inch

i noticed today that my sub making a rattling sound and hit noise when i crack the volume up.
i didn't touched the gain for a while and the noises come when i am on high volume.
it wast like this before i must say.

so i took the sub from the box to see i i can hear from where this noise is coming.
didn't hear nothing special i noticed that one of the leads is kinda touching the cone and there is
leads marks on the cone.

when i play the sub all volume up on free air i don't hear hitting sound only low rattling sound
when i put it back i can hear something hitting or hitting sound and rattling on a bit low volume.
Ive also checked the cooling hole on the bottom if there is a FOD in it didn't find nothing and the sub looks aligned.
what can it be ?
is it possible the spider lost there stiffness and i am hitting now the XMAS ?
Or is it the box fault ? too much port area ? or the port area is too little ?

i had a loose speaker wire connection do something similar to what your talking about,

once i figured it out and did it right, no more noise, there was a few burn marks on the wire where i guess it was getting hot and arcing out at full tilt

a friend though he blew his sub when it unloaded badly. we took it out of the box and it turned out the spider came unglued from the basket so i held the spiders in place and checked for coil rub. when it was aligned i ca glued the shit out of it and it is back pounding hard as ever.

If you have a loose lead and you see marks on the cone you just answered your question. When the sub is in the box the turbulent air inside the box will cause the lead to hit the cone harder buy single sided foam backed tape from home depot and put it on the cone between the lead and the cone it will stop the rattle. I had the same problem. And that worked for me.

m1 level 5s in general rip leads on triple joints often. If your having tinsel slap there is most likely something wrong

Lol my sub was doing the same thing and turns out i just forgot the tighten the bolts completely (tnuts and bolts)

Otherwise try inverting the sub to see/hear exactly where the noise is coming from.
