You don't need a liner as long as you use enough glue on the joints.

Build it right and you won't need to line anything to do with the box.

I think he's talking about acoustic dampening. If this is for car audio, don't bother because you won't notice the difference. For home audio, my standby is fiberglass insulation. Eats up standing waves like candy.

Yes for dampening. Have a focal 21wx run by sinfoni going in so I want to get the most out of it.
