I will be the nice on and answer this question. Underpowering a sub is not the cause of blowing it. Distortion from clipping will which is what will most likely occour if you try to underpower a subwoofer.

People try pushing an amp too hard by using the gain as a volume knob. If the gain is set too high it will cause the amp to clip and that has a tendency to blow a sub. There is no way you are going to blow a 500 watt sub with 100 watts if it is a clean signal.

copied from my post on another forum...

you can't underpower a speaker and kill it... period

you can help kill a speaker with a clipped signal..

why? because a severely clipped signal can have upwards of 80% more power potential than a pure sine signal..

a clipped signal will not drive a speaker as far, in excursion terms.. due to the shape of a wave.. that affects cooling..

in short, it doesn't matter what the rating says, or that somebody used to put 100000000000 watts on a driver... when it fails, it fails because of these 2 reasons:

1. the anodization / glue on the coil melts, causing the former length of wire with resistance per foot to become a chunk of metal with the electrical characteristics of a dead short

2. the mechanical limits of the driver are exceeded, either by slamming the coil into the backplate, or the top of the topplate, or exceeding the capability of the suspension, causing deflection, and rubbing the coil into the side of the motor, in the gap, which scrapes off the anodization / glue and causes the short described previously..

if your 400 watt amp, killed your 2000 watt sub.. one of those manufactuers be lying about specs.. and generally its not the company that said its a 400 watt amp, but its really doing 2kw Grin
