The guys find out if the bass from a car stereo can destroy an automobile. They rip out the interior of a car, build a giant subwoofer to fill it, and then power it by attaching it directly to the drive shaft. Wear your ear plugs for this one! Also, Grant, Kari and Tory hit the road to take on two tall tales from our mates down under. If you're driving on a rough outback road, will you get a smoother ride by driving faster? And, can you stop your windshield from shattering when a stone is kicked up from a passing car by bracing the glass with your hand?
