It's called Peel N Seal and it is in the Roofing section of some Lowes and Home Depots. A 6" x 25' roll costs about $12.50, far less than the cost/area of most real audio sound deadener.
Some people say it's the same as Dynamat but that isn't really true. Peel N Seal is more of a foilbacked tarlike substance while Dynamat is a different, denser product that sticks better, deadens sound better and is more resistant to heat. If you're on a budget, the Peel N Seal is not a bad substitute but don't expect the same level of performance.
