4th order bandpass box help (SSD x2)

[subssonicimpalass 0]

I decided to change my set-up. I want to build a forth order bandpass for my two FI SSD 12"s. I think they are the 2008 model. I am putting in my 1995 Impala SS. I plan on porting it through the back deck. Can anyone help me with the numbers I need. Such as the air space volume for the sealed and ported areas. Also for the port (@ 35 hz).

I wanted the box to be tuned to 35 hz. I'm trying to get the MOST out of these subs but with All the sound pushed into the cab and not rattling everything aound in my trunk

By the way I will be powering them with a Audiopipe AP18001.

And if anyone has done any thing similar in my same type car please post pics.

Thanks in advance!!!!!
