Complete Buying Guide for Best Under Seat Subwoofers
Choosing the best under seat subwoofer can significantly enhance your driving experience, but with so many options, it’s easy to feel overwhelmed. This buying guide will walk you through the essential factors to consider, helping you make an informed decision for your vehicle’s audio upgrade.
Essential Factors We Consider
When evaluating under seat subwoofers, we focus on several key aspects to ensure you get the best performance and value:
- Size and Fit: The primary advantage of an under-seat subwoofer is its compact nature. We assess the dimensions to ensure it truly fits under a typical car seat without obstruction. Measure your available space before buying!
- Power Output (RMS vs. Peak): RMS (Root Mean Square) power is the continuous power a subwoofer can handle, while peak power is the maximum burst. We prioritize higher RMS wattage as it indicates sustained performance and clearer bass. For most under-seat units, 100-300W RMS is excellent.
- Built-in Amplifier: Almost all under-seat subwoofers are “powered” or “active,” meaning they have a built-in amplifier. This simplifies installation and ensures the amplifier is perfectly matched to the subwoofer for optimal performance.
- Frequency Response: This indicates the range of bass frequencies the subwoofer can reproduce. A lower starting frequency (e.g., 20Hz) means deeper bass.
- Controls and Adjustments: Look for features like a variable low-pass filter (LPF) to cut out higher frequencies, bass boost for extra thump, and phase control for proper integration with your car’s main speakers. A remote bass knob is a huge convenience.
- Construction Quality: Durability is key for a device that will be subjected to car vibrations and temperature changes. We look for sturdy enclosures and reliable internal components.
Budget Planning
Investing in an under seat subwoofer can range from around $100 to over $400. Entry-level models (typically $100-$200) offer a noticeable improvement over factory bass, making them perfect for casual listeners. Mid-range options ($200-$350) provide more power, better sound quality, and advanced tuning features for discerning audiophiles. High-end units (above $350) deliver superior construction, more powerful amplifiers, and exceptional bass depth. Consider what level of bass you truly need and how much you’re willing to spend to achieve it, keeping in mind that the included wiring kits can also save you money on installation accessories.
Final Thoughts
Ultimately, the best under seat subwoofer for you depends on your specific needs, your vehicle’s available space, and your desired bass intensity. By carefully considering factors like power, size, and available features, you can confidently select a compact powerhouse that delivers rich, satisfying bass and transforms your car’s audio system without compromising your interior space. Don’t underestimate these small but mighty devices—they pack a serious punch!
Frequently Asked Questions
Q: Do I need a separate amplifier for an under seat subwoofer?
A: Most under seat subwoofers are “powered” or “active,” meaning they have a built-in amplifier. This is one of their main advantages, as it eliminates the need to purchase and install a separate amplifier, simplifying the setup considerably.
Q: How difficult is it to install an under seat subwoofer?
A: Installation difficulty varies, but generally, powered under seat subwoofers are easier to install than traditional passive subwoofers. Many come with wiring kits and clear instructions. Basic electrical knowledge (connecting power, ground, remote wire, and audio signals) is usually sufficient. If you’re uncomfortable, professional installation is always an option.
Q: Will an under seat subwoofer really provide enough bass?
A: For most listeners, yes! While they won’t match the earth-shattering bass of large, trunk-mounted subwoofers, modern under seat subwoofers deliver impressive low-frequency response that significantly enhances the car’s audio. They provide punchy, clear bass that fills the cabin, perfectly complementing your existing speakers and adding depth to your music.
Q: What’s the ideal size for an under seat subwoofer?
A: The ideal size depends on the physical space available under your specific car seats. Measure the length, width, and height carefully before purchasing. Most under seat subwoofers typically feature 8-inch or 10-inch drivers and have a low-profile design (usually 2.5 to 3.5 inches in height) to maximize compatibility.
Q: What is the difference between RMS and Peak Power?
A: RMS (Root Mean Square) power is the continuous amount of power a subwoofer can handle reliably over an extended period. Peak power is the maximum power a subwoofer can handle for very short bursts. When evaluating performance, RMS power is the more important specification as it indicates the sustained performance and overall quality of the bass output.
