The Ultimate Buying Guide: Finding the Best Car Subs For Your Money
Want to make your car audio thump? You need a good subwoofer (or “sub”). A sub handles the low, deep bass sounds that regular speakers miss. Buying the right one doesn’t have to be confusing. This guide helps you find the best bass without emptying your wallet.
1. Key Features to Look For
When shopping, keep these important parts in mind:
- Power Handling (RMS Wattage): This tells you how much continuous power the sub can safely handle. Higher RMS usually means louder, cleaner bass. Don’t just look at the Peak Power; RMS is the real number.
- Size (Diameter): Common sizes are 8-inch, 10-inch, and 12-inch. Bigger subs (like 12-inch) usually move more air, creating deeper bass. Smaller subs (like 8-inch) fit better in small spaces and sound punchier.
- Impedance (Ohms): This affects how the sub connects to your amplifier. Most subs are 2 or 4 ohms. Make sure the sub’s impedance matches what your amp likes best for maximum power transfer.
- Enclosure Type: Do you want a pre-built box (enclosure) or just the speaker (subwoofer)? Sealed boxes give tight, accurate bass. Ported (vented) boxes give louder, deeper bass but take up more space.
2. Important Materials Matter
The materials used define how long the sub lasts and how good it sounds.
Cone Material:
The cone is the part that moves to make the sound. Look for strong, light materials. Polypropylene or treated paper cones offer a great balance of cost and performance. Stiffer cones resist flexing, which keeps the bass clear, even when loud.
Suspension (The Surround):
This is the ring connecting the cone to the basket (frame). High-quality rubber or foam surrounds allow the cone to move a lot (high excursion) without tearing. Good suspension is crucial for deep bass.
Voice Coil:
The voice coil handles the electricity from the amp. Copper wire is standard. For better heat management and power handling, look for subs with a slightly larger or dual voice coil setup.
3. Factors That Improve or Reduce Quality
Quality isn’t just about price. Some design choices make a big difference in performance.
Improving Quality:
- High Excursion: This means the cone can move far in and out. More movement equals more air moved, resulting in deeper bass notes.
- Strong Magnet Structure: A large, heavy magnet keeps the cone moving precisely. This helps reduce distortion.
- Proper Mounting Depth: Ensure the sub fits where you plan to put it. If the magnet hits the car panel, the sound quality suffers immediately.
Reducing Quality (Watch Outs):
- Under-rated Power: If a sub claims huge power but uses cheap wiring or a flimsy cone, it will break quickly.
- Tiny Magnets: Small magnets mean the sub cannot handle much power, leading to muddy, quiet bass.
- Cheap Enclosures: If you buy a pre-loaded box, check the wood thickness. Thin wood vibrates itself, coloring the sound negatively.
4. User Experience and Use Cases
Think about how you listen to music. This shapes your best choice.
The Daily Driver:
If you listen to music while commuting, you need something balanced. A single 10-inch or 12-inch sub in a sealed box often works perfectly. This setup provides noticeable bass without taking up your entire trunk space.
The Bass Head:
If your main goal is shaking windows, you need high power handling and maybe two 12-inch subs in a ported enclosure. You must also budget for a strong, dedicated amplifier to push them properly.
The Space Saver:
If you carry groceries or luggage often, look at compact powered subwoofers. These are small boxes that include the amplifier built-in. They offer a nice bass boost without sacrificing much space.
10 FAQs About Buying Car Subs For The Money
Q: What is the difference between a sub and a regular speaker?
A: Regular speakers handle mid and high sounds. Subs only handle the very low, deep bass sounds, giving your music that satisfying “thump.”
Q: Should I buy a single sub or a dual sub setup?
A: A single quality sub can be very loud. A dual setup generally gives you deeper, louder bass overall, but it costs more and needs more power.
Q: What RMS wattage should I aim for in a budget sub?
A: For a good budget buy, look for a sub that handles at least 300 to 500 watts RMS. This gives you solid performance.
Q: Do I need a separate amplifier for the subwoofer?
A: Yes, usually. Most car stereos do not provide enough clean power for a dedicated sub. An external amplifier ensures the sub gets the power it needs to sound good.
Q: What does “DVC” mean on a subwoofer?
A: DVC stands for Dual Voice Coil. This lets you wire the sub in different ways (like 2 or 4 ohms) to match your amplifier better.
Q: How does the enclosure material affect the bass?
A: Thicker, denser wood (like MDF) in the box stops the box itself from rattling. Thin wood absorbs good bass energy and creates bad rattling sounds.
Q: Is a 10-inch sub better than a 12-inch sub for the money?
A: Ten-inch subs often sound punchier and fit easier. Twelve-inch subs usually go deeper in frequency. It depends on the specific model and your car space.
Q: What is “bottoming out”?
A: Bottoming out happens when the speaker cone moves so far it hits the physical limits of its structure. This usually means the sub is getting too much power or is not designed for the bass it is trying to play.
Q: Can I install a sub myself, or should I hire someone?
A: If you are comfortable running wires, especially the power wire from the battery, you can install it yourself. If wiring an amplifier seems tricky, a professional shop can do it safely.
Q: How do I know if my budget sub is distorting the sound?
A: Distortion sounds fuzzy, scratchy, or like the bass is breaking up instead of sounding smooth. Turn the volume down immediately if you hear this.
