    whats the minimum clearance needed between sub and fiberglass?

    I did a fiberglass enclosure in the spare tire well and theres almost no clearance between the bottom of the sub and the bottom of the enclosure. theres a very loud vibration of two things knockin eachother. im not sure if its the bottom of the fiberglass flexing or the fiberglass hitting the sub. i think that im gonna pull the subs and reinforce the bottom. should i take out more glass from under the sub?

    if the sub has a pole vent, you need atleast an inch behind it
    if not, then just dont let them smack against each other

    is there a hole in the middle of the magnet on the back of the sub?

    and its prolly the floor of the car and the fiberglass. you will want to sound deaden under there at least.

    Its always a good common practice to leave at least 1" if you can, or close to, behind the sub and the rear wall. Doesnt matter if its mdf, fglass, or whatever mane.

    So if it has a 3" pole vent (i.e. RF Power DVCs), you should leave 3" between the back of the sub and the back wall ...
    thats a cool helpful rule, never heard it put like that before.
