calculating resonating frequency

kickerzook · 17th February 2007, 06:39 AM

Hello every1, only been playin with car audio for a little while.

How do i calculate the resonating frequency of my car....????

The interior space of the car is too complex to model it, the easiest way to find it is to compare the response of a sealed sub in open space to the response in the car (in the same location that the intended sub enclosure will go) the response will have a peak at the car's res frequency.

note; if you intend to use a wall or a very large enclosure that can change the res frequency (usually higher)

edit; here's an example;

Yellow is sealed in open space, green is the response in a medium sized wagon (subaru forester) pink is the response in a small sedan (mitsubishi lancer)
