1. Size And Placement
- Subwoofer Size: Common sizes are 8 to 10 inches. Larger sizes like 10 inches offer deeper bass, while 8 inches are more compact and easier to install.
- Physical Dimensions: Check the overall dimensions (length, width, height). Sizes typically range between 9-14 inches long, 8-10 inches wide, and 2.5-4 inches high. Ensure it fits without interfering with the seat or passenger space.
- Vehicle Compatibility: Ensure it fits your car’s make and model. Compact cars may have less space than larger vehicles. Measure the space under your seat before buying.
- Look for a subwoofer that fits easily without modifications to your vehicle’s interior.
2. Power Output
- RMS Power: This is the continuous power the subwoofer can handle. A range of 100W to 300W RMS is ideal. Higher RMS means louder, clearer sound. At least 100W RMS is recommended.
- Peak Power: The maximum power it can handle in short bursts, usually 200W to 800W. Peak power shows its capacity for dynamic music changes.
- Impedance: Available in 2-ohm or 4-ohm A 2-ohm subwoofer draws more power; a 4-ohm subwoofer offers better sound quality.
- Look for a subwoofer with a good RMS rating that matches your sound needs and is compatible with your car’s audio system.
3. Enclosure Type
- Sealed Enclosures: Airtight, providing tight, accurate bass. They are smaller, ideal for under-seat placement. Best for genres like rock or classical.
- Ported Enclosures: Have a vent for louder bass output. They are usually larger and may not fit under all seats. Suitable for bass-heavy music like hip-hop or electronic.
- Passive Radiators: Use additional radiators instead of a port, combining the benefits of both sealed and ported enclosures. Generally larger and more expensive.
- Look for a sealed enclosure for tighter bass or a ported one for deeper bass if space allows.
4. Frequency Response
- Frequency Range: Shows the range of sounds the subwoofer can reproduce, measured in Hertz (Hz). A range between 20Hz to 250Hz is good. Lower Hz means deeper bass.
- Crossover Frequency: Built-in crossovers control the frequency range, usually adjustable from 50Hz to 150Hz. This helps direct only low frequencies to the subwoofer.
- Look for a subwoofer with a wide frequency range and an adjustable crossover for better sound control.
5. Sensitivity
- Sensitivity Rating: Measures how efficiently the subwoofer turns power into sound, in decibels (dB). A rating between 85dB to 95dB is typical. 90dB or higher is ideal for efficient power use.
- Efficiency: A subwoofer with higher sensitivity will produce louder sound with less power, helping to preserve battery life.
- Look for a subwoofer with a sensitivity rating of 90dB or higher for better efficiency and louder sound.
6. Built-In Amplifier
- Class D Amplifiers: Most under-seat subwoofers use Class D amplifiers. They are compact, cool-running, and energy-efficient.
- Power Match: Ensure the amplifier’s power matches the subwoofer’s RMS rating. For example, a 150W RMS subwoofer should have a matching amplifier.
- Additional Features: Look for features like bass boost controls, phase switches, or remote controls for easy sound adjustments.
