I am getting ready to built my next system and want to know what people think about deadening a sealed trunk? This is in a 99 Honda Acoord(Think pop can)and I will be forward firing my Fi BTL 15" and sealing the trunk off. I will be doing Second Skin Damplifer floor, doors(inner and outer), pillars, back deck and ceiling. I will probly also be doing Luxury liner Pro(luxury liner min.). I am getting ready to built the box inside the trunk. I had planed on a single layer of Damplifer inside the trunk for good measure before building the box as I won't be able to take it back out. I already have the Damplifer and will probly do a single layer just to know my trunk isn't rattling from outside the car. The trunk will probly only take $100 worth anyway. So what do you guys think?
