If you have friends that know something about audio amps, you'll find it difficult to brag just about power levels. You also have to tell them what the THD is at that power level.

If you really want to impress them, tell them that amount of power into the M80s produces the equivalent sound pressure level as standing in a ship's engine room. Which coincidentally is also the threshold of pain and can result in permanent hearing damage if listened to for 15 minutes.
