Some folks say it’s not worth it, but most audio guys I know and car restorers say that installing a sound deadening product adds minimal weight while making your old rustbucket feel like a new car without all the rattles and bass resonance. Stings a bit in the wallet, and my back and knees are not happy, but the results were worth it. Spent about $360 plus $25 in tools. Total time spent, about 5 hours.
