No,but it is something i have been thinking about for wile,i was thinking doubleing up the carpet,as i need a darker one any way.
And some of the sound proofing cone shaped stuff behind the dash,thinish layer of fome behind door cards,and some of that sticky back foam draft excluder,discretly put round the door frames.
That was just my first thoughts i havent looked into it fully,im sure someone has done it before and would have some good info as to how,and what to use.
