[edit] Earlier stat
Based on the radio report, the article contained this statement "A competitive vehicle might be a van weighing 33,000 pounds, with twelve 1,000 watt amplifiers, 72 speakers, dozens of car batteries." It was amended after reading the CNN article. Hu 22:38, 2004 Dec 11 (UTC)
[edit] Perceived Loudness
A doubling of the amplifier power results in a 3dB increase. However, this does not equate to a perceived doubling of volume. With how human hearing is weighted, a roughly 10dB increase is required for something to be twice as loud. Stephonovich 21:17, 5 February 2006 (UTC)
