Enhance the Audio With a 12-Inch Car Subwoofer

As you drive around town, you may want to enjoy high-quality audio while listening to your favorite songs. If you'd like to put in an affordable 12-inch subwoofer for your car, there are many options to consider on eBay.

What types of 12-inch subs are on sale on eBay?

Three of the most common types of 12-inch subwoofers are listed here:

  • Component subs: A component 12-inch sub just consists of the speaker itself, meaning that it won't come with a box or amplifier, and 12 inches is a pretty common size for component subwoofers. This style is often preferred by those who want to customize their sound systems.
  • Enclosed subs: This type of 12-inch subwoofer is already mounted in a box. This design offers convenience that you may want if you're looking to simplify your system.
  • Powered subs: If you get a powered new or used 12-inch sub, you'll get a woofer and an amplifier, both of which will be contained in an enclosure. Powered 12-inch subs are compact, making them ideal if you don't have a lot of extra space in your car.
Do subs fit into any vehicle?

Most of the subs you see on eBay will be able to go in most types of vehicles. However, your space may be limited or you may have specific ideas about where and how your sub will fit. There are some models designed for specific types of vehicles. They can be powered or unpowered, and they may have a finish that matches that of your vehicle's interior.

12-inch sub specifications

As you look through the wide selection of car subwoofers that are 12 inches, you'll likely see the following specifications, among others:

  • Power: RMS power ratings let you know about continuous power output, and this should match the output of your amp.
  • Sensitivity: With a higher sensitivity rating, a sub will be able to produce the same amount of sound with relatively less power when compared with a sub with lower sensitivity rating.
  • Frequency range: This will indicate how low a sub can go.
  • Enclosures: Sealed enclosures generally produce the higher quality sound in terms of accuracy. Ported and bandpass enclosures are good if you're going for volume.
  • Voice coils: Having a single voice coil is fairly standard. Subs with dual voice coils are more premium products that can be wired in various ways.
  • Impedance: Standard impedance is 4 ohms. There are also 2- and 8-ohm 12-inch subs. Again, just make sure impedance matches that of your amp.
