If this is a true story.. This wasn't due to neglecting 'break-in', I promise you. That's the result of clipped signals.
yeah i guess, my mine are clipping and i get smell not a blown coil, he never got it to smell and it was installed by professionals so they should have check it wasn't clipping before handing him the car
edit: it is a true story i wouldnt just say it when i know there is people on here that know more than me. it sucks to have a $700+ sub blown in one day because of a bad install
