What to Know About 12-Inch Subwoofers

When comparing subwoofers, there are a lot of sound and power ratings people throw around. These ratings are important in finding a subwoofer that suits your vehicle, your other equipment and your auditory preferences. You’ll also want to consider the sub’s size and mounting depth — plus its color if you’re going for a specific aesthetic. Here are a few other things to consider when comparing models:

  • Power rating: Subwoofers have both a max power rating and a “root mean square” (RMS) rating that signifies the power it can continuously handle. The peak power rating usually ranges from 400 watts to more than 2,500 watts, while the RMS rating is generally half that range.
  • Impedance: Impedance measures the sub’s resistance to the power supplied by the amp. This number is represented in ohms, with 2-ohm subwoofers demanding less power and a louder bass than a 4-ohm subwoofer.
  • Sensitivity: Measured in decibels, a sub’s sensitivity reflects how loud it can get with the power it receives. If a subwoofer has a sensitivity of 89 decibels, it can produce an 89-decibel sound with one watt of power from one meter away.
  • Frequency range: The frequency range shows the lowest and highest frequencies the subwoofer can achieve, measured in hertz.

Bottom Line: What Makes a Good 12-Inch Car Subwoofer?

When it comes time to find the right subwoofer, the final answer really depends on your preferences. If you want a louder sound and aren’t too picky about quality, a 2-ohm sub may be right for you. If you want a crisper sound, you’ll want a 4-ohm model. Similarly, the sub’s sensitivity, range and power rating will influence the quality of sound you wind up with. It’s good to carefully consider all these details, plus the brand’s reviews and reputation, before settling on a 12-inch subwoofer.
