Its difficult to answer your questions because it all depends on the quality of the components being used and how you use them. I do some work at a local stereo shop and I keep a small 30 watt Coustic amp around to demonstrate with. Many people believe that a 500 watt amp will eat a 250 watt subwoofer. While this is a legitimate concern, it isn't as big a deal as most people believe. The key is keeping your power clean up to a point just beyond your normal listening level.

The demonstration I do is I wire up my 30 watt amp to a sub that lists a power rating in the 3-500 watt range and proceed to blow it up. How? Simple...drive the amp into clipping and wait a few seconds for the voice coil to come apart. The other side of that coin is the setup I have in my car.

I have an 800 watt amp on a 300 watt sub. Is that a problem? No. The way my system is tuned, that amp will never produce all 800 of those watts. Its loud enough to make your ears bleed, but my amps will never clip, so my speakers will survive quite a bit of abuse.

The problem you run into at high volume levels is heat. Build up enough heat in the voice coil of your speaker and it will come apart. Mostly, that's kinda hard in the confines of a car because the resulting noise is so loud that it becomes uncomfortable and most people turn it down long before heat becomes an issue.

So I guess the short answer is "Be nice to it and you shouldn't have a problem".
