> Granted you dont want the amp at 100% output all the time because it shortens the life, but underpowering will never do any harm to a speaker. Overpowering will overheat them and can fuse the coils causing them to distort and make cool cracking noises. If you run yours like mine, which is at 120 db constant cruising, then you want a little extra wattage to keep the amp nice and cool. Your not competing theres nothing to worry about. You could run it on your amp now, but your amp would get hot.

yeah and probably at an astronomical 17 volts too.  
to whoever said underpowering never hurt and claimed i dont know what a coil is let me explain it for you… excessive distortion from an over driven amp CAN shorten the life of a subwoofer. the voice coil vibrates along the magnet structure and carries the current so that it is always moving in a plane perpindicular to the magnetic field so the force always acts on the same axis, so if that vibration becomes distorted because of overloading an amp your coils can shit out because of uneven distibution of force and power. correct???
