Plywood and more Sound Proofing

Stripped out the remainder of the wall panels and used the old panels as templates to cut out new ones out of 4mm thick plywood. Still waiting for the carpet to arrive so just a quick check to make sure everything's going to fit then continuing with the roof flashing sound deadening (also using Dynamat Xtreme behind where the rear speakers are going to be situated) and the sound proof underlay over all that.
