Car stereo systems typically fall short of satisfying bass. Enter the 15” car subwoofer. It can deliver a satisfying thumping bass as you listen to your tunes on the road. While most 15” car subwoofers have an output of 1,000 to 2,000 watts, power can be as modest as 500 watts and as impressive as 4,000 watts. The large size of the cone can make it vulnerable to damage from the heat or being knocked around in the car if its made of flimsy material. Though not as large as its 18” big brother, the 15” car subwoofer isn’t tiny, so there needs to be ample room for it. Some subwoofers of this size give better frequency distribution than others, which will prevent distortion.
