It's typically the poorly recorded tracks that are clipping your signal significantly and the end user still turns up to 100% which is actually a highly distorted and very much clipped signal because the recording amplitude is different than what's expected(whether higher or lower). And an "underpowered" sub is not ruined because it's not getting enough power. It would only ever get ruined with distortion and clipping. The end user who thinks that gain = volume is the culprit...not an amp that puts out a clean 30watts vs. a clean 4.2 jigawatts. Overpowering a sub WILL hurt a voice coil. One more time, the primary culprits, assuming everything works right, are misunderstood gains, poorly recorded tracks, or install.

That's why customer service is such a B. in car audio. The manufacturer knows this but the audience doesn't.
I have been reading up on this for most of the day. I am now a subscriber to this logic, even though it goes against everything I was taught years ago. Hell, even the manufacturers would send back a "Possible Cause" statement with the repaired/replaced subwoofers claiming "Damaged voice coil possibly due to inadequate wattage". And Reps from the manufacturers would hold seminars and would tell us that the worst thing we could do to a subwoofer, is to connect it to an amp that is not powerful enough to deliver the appropriate RMS. I guess, as with most things, audio has evolved since then (8-12 years ago). Carry on.
