Im about to build a box for my wife's new little lanzar max 8in sub and Iv had nothing
but trouble trying to figure out how big around and how long to make it ? Iv been using
the12v.com's round port calculator idk im stumped lol
Im thinking a down fire box about .75cu tuned to 34hz or so.
Its going in a 2010 jeep patriot I'll prolly make the box short and long so she still
has room to put her stuff lol
Thanks for any help!

There's a calculator on the precision port website. Not sure how accurate it is though..
