Has anyone installed DynaMat in their G? If so, how was it? Where did you put it? Can you tell a difference?

Yep yep! I have! I've put it all over my trunk and some near the spare! Definetly a better clearner sound inside the car! I have a sedan btw

 

Yep, installed under the carpet, seats, trunk, trunk lid, all 4 doors and rear deck lid. This was fairly expensive but, I like to hear my 5.1 Dolby Digital surround sound. I would highly recommend that you at least get the trunk lid and rear deck to keep any unwanted vibrations and rattling down.
