so to find the resonant frequency of a car. get a spl meter like the one at radio shack. play pink noise and turn it up to you get like 100db. then play frequency tracks and watch the meter to see the highest db at the same volume. Correct?
So if i do that before a put a wall in, would the RF still be the same? I would think that it would change but I've never done this so i have no experience with it.
Then once i have the RF. I need to make the box so that its tuned for the same frequency to get the highest spl with whatever subs and in that car. correct?
If this is the case, the only thing you need to look for in subs spl wise is power handling? Correct?
Why would you care about anything else(sub wise)?
Teach me oh wise ones!
Sorry if this is confusing.
