What is a subwoofer and why do I need one for my stock stereo?
A subwoofer is a specialized speaker designed to reproduce low-frequency sounds, typically in the range of 20 to 200 Hz. This capability allows it to provide depth and richness to your music or audio experience that regular speakers cannot achieve. If you appreciate genres like hip-hop, EDM, or even cinematic soundtracks, a subwoofer can help you better feel the bass and overall sound dynamics.
For stock stereo systems, which often lack robust low-frequency output, adding a subwoofer can significantly enhance audio quality. It fills in missing frequencies and creates a fuller sound, making your listening experience more immersive. As a result, investing in a high-quality subwoofer can take your car audio setup to the next level.
How do I choose the right subwoofer for my system?
