The Ultimate Guide to Buying a Cheap Car Subwoofer
Adding a subwoofer to your car stereo system makes music sound much better. You get deep, rumbling bass that you can feel. You don’t need to spend a lot of money to get great sound. This guide helps you pick the best budget-friendly car subwoofer.
Key Features to Look For in Budget Subwoofers
When shopping for a cheap subwoofer, certain features matter most. Focus on these to ensure you get good value for your money.
Power Handling (RMS vs. Peak)
Subwoofers have two power ratings. RMS power is the continuous power the speaker can handle safely. This is the most important number. Peak power is the highest power it can handle for a very short time. Look for a decent RMS rating, even on cheap models. Aim for at least 150–300 watts RMS if possible.
Size Matters
Subwoofers come in different sizes, usually 8, 10, or 12 inches. Bigger subwoofers generally move more air and create deeper bass. For small cars or tight spaces, an 8-inch or 10-inch unit works well. 12-inch subs give the deepest bass but need more space.
Enclosure Type
Cheap subwoofers often come in pre-built boxes (enclosures).
- Sealed enclosures give tighter, more accurate bass but might not be as loud.
- Ported (or vented) enclosures are louder and hit lower notes but can sometimes sound “boomy.”
For beginners, a pre-made sealed box is often simpler.
Important Materials for Durability and Sound
The materials used in the subwoofer cone affect how it sounds and how long it lasts.
The Cone Material
The cone is the main moving part of the speaker.
- Paper or Pulp Cones: These are common in budget subs. They sound good but can be damaged by moisture.
- Polypropylene (Poly) Cones: These are more durable and resist weather changes better. They are a great choice for affordable setups.
The Surround Material
The surround is the flexible ring that connects the cone to the speaker frame. Cheap subs often use foam. Better, slightly more expensive subs use rubber. Rubber lasts longer and handles harder hits better.
Factors That Improve or Reduce Quality
Not all cheap subwoofers perform the same. A few things make a big difference.
Voice Coil Design
The voice coil moves the cone. Single voice coils are easier to wire. Dual voice coils offer more wiring flexibility, which can sometimes help you match the subwoofer better to your amplifier, leading to cleaner sound.
Build Quality and Magnet Size
Check the frame (basket) holding the speaker together. Stamped metal baskets are common in cheap models. Ensure the magnet structure is large enough. A bigger magnet helps control the cone movement, which reduces distortion (unwanted noise) when you play music loudly.
User Experience and Use Cases
Think about how you plan to use your new subwoofer.
The Casual Listener vs. The Bass Head
If you just want music to sound fuller, a smaller, sealed 10-inch sub will work perfectly. It blends well with factory speakers. If you want loud, earth-shaking bass for hip-hop or EDM, you need a more powerful 12-inch sub, likely in a ported box. Remember, louder bass needs a separate, matching amplifier—don’t rely only on the power from your car stereo.
Installation Simplicity
Many budget subwoofers come as “powered enclosures” (they have the amplifier built in). These are the easiest to install. You connect them to your car battery and speaker wires. Traditional subs require you to buy and wire a separate amplifier, which takes more skill.
10 Frequently Asked Questions (FAQ) About Cheap Car Subwoofers
Q: Do I need an amplifier for a cheap subwoofer?
A: Yes, almost always. Most car stereos do not provide enough power (wattage) to run a dedicated subwoofer effectively. You need an external amplifier matched to the subwoofer’s RMS rating.
Q: What is the smallest size subwoofer I should buy?
A: While 8-inch subs exist, a 10-inch subwoofer usually offers the best balance between size, bass depth, and cost for budget buyers.
Q: Can I install a subwoofer myself?
A: If you buy a powered enclosure, installation is relatively simple. Installing a passive sub with a separate amp requires running power wires from the battery, which is more complex.
Q: Will a cheap subwoofer sound bad?
A: Cheap subs sound much better than no sub at all. Quality often drops when you push them past their limits. Keep the volume reasonable for the unit’s power rating, and the sound will be good.
Q: What does “DVC” mean on a subwoofer?
A: DVC stands for Dual Voice Coil. It means the speaker has two sets of voice coils, giving you more options when wiring it to your amplifier.
Q: How much space does a subwoofer take up in the trunk?
A: A 12-inch subwoofer in a box can take up a significant chunk of trunk space. Measure your trunk before buying to ensure it fits.
Q: Should I buy a subwoofer alone or in a box?
A: For beginners and budget buyers, buying a subwoofer already mounted in a matching enclosure (a “sub and box combo”) saves time and ensures the box design matches the speaker’s needs.
Q: What is the main danger of buying the cheapest sub available?
A: The main danger is blowing the speaker quickly because the materials cannot handle the power or the magnetic structure is weak, leading to distortion.
Q: How do I connect the subwoofer to my existing factory stereo?
A: You will need an amplifier that accepts “high-level inputs” or a line-out converter (LOC). This device takes the speaker-level signal from your existing stereo and converts it into a low-level signal the new amp can use.
Q: Is a ported or sealed box better for cheap subs?
A: Ported boxes often sound louder with less power, which can be appealing for budget systems. Sealed boxes provide tighter, cleaner bass, which is better for accuracy.
