I have been into car audio for 6-7 years now. Over this time I found that after market speakers are easier to blow than stock speakers. Has anyone else experienced this, or is it just me? Does anyone know if there is any explanation for this? My theory is that stock speakers are cheaply made without sensitive materials so they can handle more distortion and abuse. Aftermarket speakers are made of sensitive materials and precise construction so they are much more vulnerable to distortion and abuse. Does this sound accurate? Thanks to all who can help.
