Well they destroyed a 300SD. I posted the following on one of their fan sites

"I must say I was sad to see a Mercedes diesel sacrificed to try and bust this stereo myth. A Mercedes Benz is designed to be very tough to protect people from accidents on the autobahn where there is no speed limit. The particular car they used has a typical curb weight of about 3600 pounds. I recall an episode of "The Worlds Scariest Police Chases" on Fox where the police were trying to arrest a car theif that stole one of these cars. A police officer tried ramming the Benz off the road. The end result was a mangled police car and a few minor dents and scratches on the Mercedes. Owners of these cars reffer to them as panzer wagons for a reason. If the myth was you can build a stereo loud enough to tear a very tough car apart they succeeded in busting it. If they are trying to bust a myth that you can build a stereo loud enough to tear an average car apart they failed to bust it.

Some might say that the Benz was a good choice because it was tough because these Decible Dragracers reinforce their cars. These Decible Dragracers are reinforced for two reasons. One is to keep the sound inside where the sensor is to make it as loud as possible for the sensor. The other is to keep the car together. They have incentive to keep the car together to keep the volume high for the sensor. Once again the myth was not that you can build a stereo loud enough to tear a reinforced car appart. If they are going to say that you can't do it they are going to have to do it on a car without a reputation for stregnth and being well built. They need to use a car like a Geo Metro or a Yugo and they are going to have to do it Mythbusters style. If the a window or a sunroof pops out they are going to have to replace it with something stronger to show what it actually takes to blow a car appart with a stereo.

They could have done a few things to make the speaker more durable and powerful. One was to make a lighter speaker cone. I'm sure that 1/4 inch aluminum plate is not very light. They could have used a small satellite dish or made it from carbon fiber or fiberglass. Connecting the connecting rod off center like they did was begging for failure. Woofers also are designed to travel straight forward and backwards with out allowing the cone to wobble side to side. To get this they have a membrane at the base of the cone near the voice coil as well as around the edge of the cone. This may not work for such a large speaker but a mechanism to get a similar result can be built."
