Dyna-Mat adds a lot of weight to the car so I would use it sparingly. Before adding things to the car first make sure it is in good condition. This means no exhaust leaks, good door seals, the rear glass is sealed all around, especially along the bottom, all holes,openings, and penatrations are sealed on the firewall in the rear and the bulkhead in front. The headliner is more than for good looks, it too, absorbs some sound. Things loose and rattling or rolling around adds to the sounds so fix rattles, squeaks, etc. Loose items in the trunk and the cargo shelf should be secured. Better speakers will help, less distortion so you can hear more clearly at lower volume levels. In the end the Delorean, by today's standards, is a noisy car. BTW a lot of road noise can be generated by tires. When I changed to the Michelin XLT's the car rides a lot quieter.
