lol, this thread has totally changed topics. oh well. a sub being overpowered will not cause wrong notes. It will however smell pretty bad. It should play right up until it blows... You'll hear something like two plastic pieces being slapped together and then the cone will seize. Then the normal blue smoke will come out if it’s a ported box. I have never seen a sub get blown in a sealed box… which now I’m interested in doing so. Think I might have to try it!
