Please if anyone knows this frequency let me know. I plan to compete in SPL and I must know my skoda's resonant frequency in order to max out my sonud. IF YOU KNOW PLEASE SHARE IT WITH ME. Thanks

Hello.

I use in my Felicia 48hz but the frequency depends of the box you have.

Try and say something.

Here is what I have now, but what I want is to change the box because when properly tuned it can go +3dB. Now I've measured 139,2 dB. Since than I've changed the wiring (Dietz 35mm2 OFC), I've changed the battery (Exide Maxxima 900DC), and all I have to do now is chage the box and tune it properly and I can go well over 145 dB in street A. (these are two Pioneer 10" subwoofers TS-W257D4, Amp is Shark SRF-1000 Blue)

Which frequency you use when you get the 139,2 dB??

50 Hz

why?

Try 48 it might goes well, about to more than 141db. This is my opinion but we have a diferent felicia. See my project and you see the diference.

if you don't mind to put your link here because I'm having a real hard time finding things in this forum. thanks in advance

Because of your box is more near the rear of the car you can have more db.

I try my subs on the rear on the old box and i get 145.7db with 48hz so you can get more db from your system.

Dont need to thanks, if i can i will help.

there are no pictures in there only a movie on youtube and your setup looks great .... wish I could have seen the car too. Here are a coupple of my movies on youtube

I dont understand wow the pictures dont show, i just saw them.

The box you have it was you that build or you buy like that???

The material that you have inside the box it should be on the wall´s and not on the front of the portic. You lose db like that. Take it of and try.

yeah I know about the material, but since this is my listening box, I don't mind. Thats why I want to build another box so I can use that one for dB drag, and this one for everyday use . anyway I will tune my box to 48 Hz as you suggested and we will see what happens . thanks for your help, I can't believe noone else didn't say anything. they could have tried . thanks

No problem. If you need any more help, just ask, i will try to help you the way i can. Iam not an expert but all the help is good, right?
