Inside the car was Jeremy Boyd, an employee of Car Toys, a car stereo shop in downtown Seattle.
Boyd then demonstrated how an $80,000, 161-decibel car stereo sounds — and feels. Or, as Boyd's co-worker describes it, "40,000 watts of pure, lovely volume."
With Awolnation's "Sail" blasting from the speakers, Boyd, in the driver's seat, and his co-worker can be seen flinching while the top of the Escalade's dashboard flaps wildly to the bass.
Boyd said the Escalade is driven in public, but the full potential of its sound system is saved only for car shows.
Seattle, as you may recall, has a thing for loud noises. On Oct. 13, 2013, fans of the Seattle Seahawks (known as the 12th Man) set a Guinness record for crowd noise, registering a decibel level of 137.6.
The Seahawks play host to the New Orleans Saints in a NFL Divisional Playoff game Saturday.
