What is a Car Subwoofer?
A car subwoofer is a specialized speaker designed to reproduce low-frequency sounds (bass) in your vehicle's audio system. Unlike regular car speakers that handle a wide range of frequencies, subwoofers focus exclusively on the lower end of the sound spectrum, typically below 100 Hz.

Frequently Asked Questions

What's the best car subwoofer for 2025?
The best subwoofer depends on your budget, space, and music preferences. For premium sound quality, consider Audiomobile or JL Audio. For best value, Rockford Fosgate offers excellent performance per dollar. Kicker provides high-power options for smaller spaces.
How much should I spend on a car subwoofer?
Entry-level subwoofers cost $100-300, mid-range options run $300-600, and premium models range from $600-1200+. Budget $150-500 additional for professional installation and necessary accessories like amplifiers and wiring kits.
What size subwoofer should I buy for my car?
Size depends on available space and desired output. 8-10" for compact cars, 12" for most sedans, 15"+ for SUVs and maximum bass. Consider browsing our complete subwoofer collection to see size options.
Do I need an amplifier for my subwoofer?
Yes, subwoofers require dedicated amplifiers. Powered subwoofers have built-in amps, while passive subwoofers need external amplifiers. Check our amplifier selection for compatible options.
What's the difference between RMS and peak power?
RMS is continuous power handling - the most important spec for real-world performance. Peak power is maximum momentary power - useful for marketing but less practical for daily use. Always prioritize RMS ratings when selecting subwoofers and amplifiers.
Which is better: ported or sealed subwoofer box?
Sealed boxes provide tighter, more accurate bass ideal for rock, jazz, and classical music. Ported boxes are louder but less precise, better for hip-hop and electronic music. Choose based on your music preference and available space. Consider our subwoofer enclosures for both options.

Choosing the right car subwoofer involves balancing space, power, budget, and sound quality preferences. Whether you're looking for deep bass for hip-hop, tight bass for jazz, or thunderous output for electronic music, there's a perfect subwoofer for your needs.
