My sub sounds alot weaker than usual, need help.
I have an audiobahn 15" subwoofer comming from a rockfordfosgate amp with infinity component all around.
The system has been sounding great for about a week, but recently a retarded passenger turned the volume up WAY to loud (max volume) and ever since the sub seems like it has no power. Does that mean the sub is blown?
The amp is quite a bit underpowered for the sub, the rms is a few hundred watts under, so that made me think it would be hard to blow it??? The less powerful base doesn’t sound as clean either.
Also some times when I turned the headunit off the sub was still getting feedback and hitting slightly but not to any beat it was random. TIA for any help!

Go and push down on the subwoofer ... does it scrape a bit when you do it? You will be able to feel it ...it'll feel like its rubbing on sandpaper while moving.
If you can ... get a multimeter and check the resistance of the subwoofer (you can just check it at the amp)
It may be blown, do these two tests for more info.

If you over drove the amplifer putting into clipping you can easily smoke a speaker rated at hundreds of watts more than your amplifer is rated. Most people I here thumping their system are driving it into clipping ... sounds like finger nails on a chalkboard but they can't hear it.

underpowering a speaker can be just as bad as overpowering it. The clipping they refer to leads to many speaker deaths. Think of it this way, instead of the wave being a smooth up and down motion, its almost like it chops off the top of the wave and now you these points on it instead of a smooth line

clipping amps are not good for speakers though
