Quick fiberglass box question..??

[UVaJester]

I am fiberglassing individual speakers box to hold one Solobaric 12s on each side of my trunk. Question; do you put down Dynamat before you mold the fiberglass to the trunk, or can you apply this later after you have built the box? The boxes are going to be removable, so I can take the system out if I have to. Thanks for everyone's help.

well it depends on how they are going to fit in. I would do it either way really. You will have to put something down over the dynomat or spray it with a release agent so your mold will not stick to it. If you decide to mold then do dynomat underneath be sure when making the mold to compensate for the dynomat or it may not fit right when you dyno then put the mold back in.
