Beat'n Down Yo Block
my car has aftermarket 26-inch diameter chrome wheels, requiring an altered suspension so they can fit on the car without rubbing against the fenders. this results in a new perspective, as if i were seeing the road like a 7-foot-tall basketball player
as Unk is "beatin' on down ya block" (driving his car down the street your house is on, with his stereo system turned up) the bass from his subwoofer speakers is so strong that it shakes pictures hanging on your wall to the point that they fall down
DJ unk is reffering to subwoofers of brand Kicker - they produce loud bass tones which you can feel in your body since the sound waves are so deep. He is saying the feeling will be like getting kicked by a karate fighter
