2008 Yaris sedan ‘S’ sound deadening project.

I got this from Image dynamics forum when I was asking for an advice between sealed or ported in my sedan:

1) when ever you place a sub in a box ( ported or sealed ) in the trunk of a car you will have to deal with the transfer function of the volume of air in that trunk.
Simply put larger the trunk thicker and heavy the lower octaves sound plus the notes feel lethargic.

2) A direct input to the cars interior is the best approach for best overall SQ but not necessarily what some people want in the bass tone ( to flat sounding to their ears )
