i was wondering if anyone has heard or seen anything like this..well a couple years back i bought 2 12" jl w3 d4 subs and a ported box..brand new..well bout 4-5 months later i was drivin down the road ..it was hittin hard as hell..but then i heard a loud thump in the box..when i got home i took the subs out and to find the magnet fell off one of the subs..im wonderin what happen..what caused this..
I own a sunfire sub which is similar to JL, and the magnet fell off that as well. Took it to the store to fix it and it fell off again 2 years later. I don't know wut is up with that though, just take it to a place to fix
