Are car subwoofers illegal to use on the road?

Is it illegal to drive with a loud music on? No, car subwoofers and speakers are not illegal, its just a rumour that spreads across the world! But still its best to check with your traffic law, as laws can change anytime! You might get a ticket or a fine, if your playing really loud music with lots of bass in your car, when everybody is asleep in bed!
