New box for my Kickers

Recommended Posts

Whats going on guys? ;)

Building a new box for my 2 12" L5's and i'm curious about the tuning i should go with. I will have a removable port in the center. The main port will be for SPL. What would be the optimal SPL tuning frequency for a Grand Prix? The box is in the trunk facing the back of the car. I was going to just go with 40hz, but thought i'd get some input from you guys. I have no idea what the resonant frequency of my car would be... maybe someone can venture a close guess.

The port that will slide in is for SQ to change the tuning to around 29-30hz

Thanks guys! :)

thats what i should tune the box to... or the resonant frequency of the car, requiring the tuning of like 48hz?

thanks!

That is the resonant of the car. The box tuning depends on the size of the box. It could be anywhere from 42 Hz up to 52 Hz. Any idea on how big you box will be?

If you want to peak at the res. freq. then tune the box ~10Hz lower than the res. freq.
