Choosing Your Car’s Bass Powerhouse: A Dual Subwoofer Buying Guide
Adding dual subwoofers to your car seriously boosts your music experience. You get deeper, louder bass. But picking the right setup can feel tricky. This guide helps you choose the best dual subs for your ride and your budget.
Key Features to Look For
When shopping for dual subwoofers, keep these important features in mind. They decide how loud and clear your bass will sound.
Power Handling (RMS vs. Peak)
- RMS Power: This is the real power the subwoofer can handle continuously. Look for a higher RMS number. This means stronger, more reliable bass.
- Peak Power: This is the maximum power the sub can handle for short bursts. It’s less important than RMS but shows potential for loud music.
Impedance (Ohms)
Impedance, measured in ohms, tells you how much electrical resistance the sub offers. Most car amplifiers work best with 2-ohm or 4-ohm loads. Make sure your subwoofers match your amplifier’s required impedance for the best power transfer.
Sensitivity Rating
Sensitivity measures how loud the subwoofer plays with a certain amount of power (usually measured at 1 watt). Higher sensitivity (like 90dB or more) means the subs get louder with less amplifier power. This is great if you have a smaller amp.
Enclosure Type
Dual subs usually come in two main box types:
- Sealed Enclosures: These boxes offer very tight, accurate bass. They need more power to get really loud.
- Ported (Vented) Enclosures: These boxes have a port or vent. They play much louder and hit deeper notes easily, but the bass can sometimes sound slightly less controlled than sealed boxes.
Important Materials and Construction
The materials used in the subwoofer cone and surround greatly affect sound quality and durability.
Cone Material
The cone moves air to create sound. Good materials include:
- Polypropylene: This is common. It resists moisture and handles heat well, making it durable.
- Paper/Treated Pulp: This material often provides a very natural, musical sound but needs careful protection from humidity.
- Kevlar or Carbon Fiber: These lightweight, stiff materials help the subwoofer respond very quickly, leading to cleaner bass, but they usually cost more.
Voice Coil and Surround
The voice coil needs to handle heat. Look for **high-temperature voice coils** (often aluminum or copper). The surround—the flexible ring holding the cone to the basket—should be made of durable, flexible material like **high-grade rubber** to allow for long cone movement (excursion).
Factors That Improve or Reduce Quality
Quality isn’t just about the numbers; it’s about how well the parts work together.
Factors That Improve Quality:
- High Excursion (Xmax): This is how far the cone can move forward and backward. More Xmax means the sub can move more air, resulting in louder, deeper bass without distortion.
- Strong Magnet Structure: A large, heavy magnet provides better control over the cone, especially at high volumes.
Factors That Reduce Quality:
- Underpowered Amps: Using an amplifier that cannot supply the RMS power the subs need will cause the amp to “clip” (distort), which can quickly damage your new subwoofers.
- Cheap Enclosure Material: Thin, flimsy MDF (Medium Density Fiberboard) boxes vibrate easily. This vibration colors the sound, making the bass muddy instead of clean.
User Experience and Use Cases
Think about where and how you listen to music most often.
Daily Driving and Music Enjoyment
If you just want great sound quality for everyday listening, focus on **sealed enclosures** and subs with **stiffer cones**. These systems deliver tight, musical bass that blends well with your existing speakers.
Competition and Loud Output
If your goal is to win sound contests or just blast music extremely loud, you need **ported enclosures** and subs designed for **high power handling (high RMS)**. These setups move massive amounts of air but might sacrifice a little bit of sonic accuracy.
Space Constraints
Dual subwoofers take up serious trunk space. Always measure your available space before buying. Some manufacturers offer very compact, shallow-mount subwoofers if space is tight.
10 Frequently Asked Questions (FAQ) About Dual Car Subwoofers
Q: Do I need a new amplifier for dual subwoofers?
A: Most likely, yes. Dual subwoofers demand more power than a factory stereo provides. You need a dedicated amplifier rated to handle the combined RMS power of both subs.
Q: Will dual subwoofers fit in my trunk?
A: They take up significant space. Always measure the depth, height, and width of your trunk opening and compare it to the enclosure dimensions listed by the manufacturer.
Q: What is the difference between a dual voice coil (DVC) and single voice coil (SVC) sub?
A: DVC subs have two separate voice coils on one cone. This gives your installer more wiring options to achieve lower impedance loads (like 1 ohm) with your amplifier, often increasing power delivery.
Q: How do I wire two subwoofers together?
A: You can wire them in series (adding the ohms), parallel (reducing the ohms), or series-parallel. This wiring choice must match the stable impedance rating of your amplifier.
Q: What impedance (ohms) is best for dual subs?
A: The “best” impedance is the one that matches your amplifier’s stable load. Many powerful amps perform best at 1 or 2 ohms, so many people wire dual subs to hit those lower impedance targets.
Q: Do I need a special battery for dual subs?
A: For moderate systems, the factory battery is usually fine. If you run extremely high power (over 1500 watts RMS), you might need an upgraded high-output alternator or a secondary deep-cycle battery to prevent dimming headlights.
Q: Can I use two different brands of subwoofers?
A: It is strongly recommended that you use two identical subwoofers. If they have different power handling or sensitivity ratings, one will overpower or underperform compared to the other, resulting in unbalanced sound.
Q: What enclosure thickness is necessary for good bass?
A: Most quality enclosures use 3/4-inch (19mm) MDF. Thicker material reduces box resonance, leading to cleaner, tighter bass response.
Q: Will dual subs drain my car battery quickly?
A: Yes, they use a lot of power when played loudly. If you frequently listen at high volume, you might notice your car battery drains faster when the engine is off.
Q: What is “break-in” time for new subwoofers?
A: Break-in is a short period (usually 10 to 50 hours of use) where the suspension components (the rubber parts) loosen up. After this time, the subs will reach their full potential for deeper excursion and volume.
