Was almost enough to do my full trunk on my 2012 civic si. I have exhaust and a subwoofer that were making a lot of rattles and drones in the trunk. Took everything out and covered about 70% of everything including the wheel wells and the rear deck support, even put some under my spoiler and behind my license plate. Now, quieter ride and no vibration from the trunk inside OR outside the car even with bass cranked up. This is a great product and I would definitely recommend.
