Did some sound deadening. One Amazon Basics 9.8" x 15.7" 34 pack, and one Amazon Basics 14.5" x 10" 10 pack. The 34 pack sheets are thinner than the 10 pack. The 10 pack is 80mil and the 34 pack is not fwiw. Installation was easy enough. Removing all the plastic panels is easy. Watch a YouTube video on how to remove one of the doors and just rinse and repeat around the car using your best judgment/feel on where the clips are. You do need a decent amount of force to pull the panels off. Make sure to buy some replacement clips before you take any panels off because one will break, I promise you. I would say it is worth it but I do enjoy taking things apart cleaning them and putting them back together. The car does sound less like a tin can but don't expect for it to sound like an SUV all of a sudden. Most of the cabin noise comes from the tires of course but after that it is the rear passenger trunk area where the cubby is. Behind that is literally nothing. Straight bare metal. I can fit my entire arm up to my elbow and wave it back and forth the entire C pillar. I put 2 full sheets up there alone and another 1.5 sheets to cover the wheel well/under the small window. Focus on the trunk area first!
