I had several questions regarding the real sound levels of 45W+45W, so I decided to make a video about it.
The general guidelines of sound levels are:

• A typical conversation occurs at 60 dB – not loud enough to cause damage.

• A bulldozer that is idling (note that this is idling, not actively bulldozing) is loud enough at 85 dB that it can cause permanent damage after only 1 work day (8 hours).

• When listening to a personal music system with stock earphones at a maximum volume, the sound generated can reach a level of over 100 dB, loud enough to begin causing permanent damage after just 15 minutes per day!

• A clap of thunder from a nearby storm, a Jet plane taking off (120 dB) or a gunshot (140-190 dB, depending on weapon), can both cause immediate damage.

This video was recorded in an open living room, with the speakers laying on the table meaning that the acoustic properties of the sound generated are greatly diminished. Even with these conditions, 45W+45W can produce levels of around 120db. So now you have a good idea of how loud this will be, when properly installed in the contained space of a car.

Please note that camera microphone does register levels higher than 85db.


The song "Get Back" by The Beatles gave me the highest levels of around 127db, but my neighbor complained which cut my test recording short before I could find the loudest level.
