    based on some port program and the size of the box they said 2'' was ok and the length of the port gets longer with a big size like 3 or 4
    so sound good bass from a 2inch port, what size shouldi go to???

    You will have port noise with a 2" port. That program you used is crap if it suggested a 2" port. I would only use a 2" port with a 6.5" subwoofer.

    I would suggest a 4" round port. The problem is the length will have to be very long and folded inside the enclosure and take up that 1.7 cu ft.

    That is the problem with trying to ghetto rig a sealed enclosure to a ported enclosure. Its not easy.

    It is much easier and the end result will but MUCH better by building a ported enclosure.

    you are right i spoke with mtx and they said need 2.0 to make it ported, don't have that much room in a lincoln mark vii trunk .
    i am trying to make the bass deep like a ported.
    i used poly foam but not deep like port still trying

    If you want deep bass within a small enclosure...you need more power.

    Hoffmans Iron Law....read up about it.

    or try a slot port... some on the inside and some on the outside of the box
