What Makes a Great Subwoofer?

Before diving into specific products, it’s helpful to understand what qualities make for an excellent car subwoofer system. Here are the key factors to consider:

  • Power handling – The power RMS and max wattage ratings indicate how much amplifier power the sub can handle. Match this closely to your amplifier to optimize sound and avoid damage.
  • Frequency range – This spec indicates the low frequencies reproduced by the sub, measured in Hz. A range down to at least 25-30Hz is ideal for deep, rich bass.
  • Enclosure – The box or enclosure plays a big role in sound. Sealed boxes offer tight, accurate bass while ported boxes emphasize loudness and deep lows.
  • Voice coils – Dual voice coils offer more wiring flexibility and allow you to run the sub in stereo or parallel.
  • Sensitivity – Higher sensitivity translates to louder volume capabilities off less power. Around 85+ dB is excellent.
  • Brands – Stick with trusted brands like JL Audio, Alpine, Rockford Fosgate, Kicker, and Pioneer for proven performance.

With those basics covered, let’s get into this year’s top subwoofers to truly shake up your ride!

Pro Subwoofer Installation Tips

Installing your new sub properly ensures you’ll get the most performance possible. Follow these guidelines:

  • Model the optimal sealed or ported box size and volume for your sub’s specifications using free software like BassBox Pro. Use high-grade MDF or birch plywood.
  • For ported boxes, carefully calculate the ideal port size and length for proper tuning. Round ports prevent turbulent airflow.
  • Set the subwoofer’s low pass filter on your amplifier at around 80-100Hz to remove highs and let the sub focus on bass.
  • Add polyfill fiber stuffing material to sealed boxes to increase bass response. For ported boxes, add it lightly to reduce port noise.
  • Make sure your amp provides sufficient power to match the subwoofer’s RMS rating for full, clean output.
  • Allow the sub’s suspension to break-in over 10-20 hours at moderate volume to loosen up and improve bass response.
  • Experiment with subwoofer placement to find locations in your vehicle that produce the loudest, smoothest response.
  • Use sound damping materials liberally throughout your car’s interior to prevent rattles from massive bass vibrations.

Proper planning and installation will allow your new subwoofer to really sing and transform your car into a rolling concert hall!

FAQs about Car Audio Subwoofers

What size subwoofer should I get?

For most systems, 10, 12 or 15-inch subs provide a great blend of output and space efficiency. Make sure it will fit in your vehicle’s available locations. Also match the size to your desired box volume; larger subs need more internal air space.

How much power do I really need?

Choose an amp that can provide at least the sub’s RMS power rating. Provide extra overhead if you want loud volumes with the subwoofer pushed hard. Underpowering distorts the sound, while overpowering risks damage.

What wiring kit should I use?

Use a wiring kit designed for your amp’s power – Rockford Fosgate, Knukonceptz and Sky High Car Audio make excellent kits for most installs. Getting clean voltage to your amp prevents problems.

Should I use a sealed or ported sub box?

Sealed boxes provide accurate, punchy bass and allow smaller enclosures. Ported boxes emphasize loud, deep bass and output but require more precise design and space.

What’s the best brand for car subwoofers?

Top brands like JL Audio, Alpine, Rockford Fosgate, Kicker and others consistently deliver great car subs. Stick with respected makers for reliable performance.

Do I need an enclosure for my car subwoofer?

Yes – subwoofers require carefully designed enclosures for ideal bass response. Do not install a sub unmounted in your trunk, the resulting sound will be poor.

How much does professional installation cost?

Simple setups often run $150-300, but costs vary widely. Complex multi-sub systems with extensive custom work can cost over $1000. Doing the work yourself saves tremendously.

How long do car subwoofers last?

With proper power levels and enclosure design, quality subs will provide 5-8 years of enjoyment before needing replacement. Hard use or overpowering decreases the lifespan.

Is adding a subwoofer to my car hard?

It’s not too difficult with proper planning – determining optimal enclosure design and wiring take the most work. If not comfortable, hire a professional for installation.
