Benefits of Subwoofer

  • Enjoy sounds normal speakers can’t reproduce. Most speakers start dropping off at about 50 hertz, which will deprive you of full clarity and depth of bass tones. The best 15-inch subwoofer will reach down to 20 hertz or lower. With these kinds of speakers, you won’t miss a kick drum, pipe organ, or bass guitar. A 15-inch subwoofer lets you enjoy a more immersive sound experience compared to your normal speakers.
  • Play loud music without distortion. In stock car systems, the woofers in your speakers might experience some trouble keeping up with the tweeters and mid drivers when you play music at high volumes. The best subwoofer plays low music notes effortlessly and distortion-free regardless of how loud you play it.
  • Add control and speed in low-end transients. In several genres of music, the vocals and music start and stop rapidly, which takes a toll on smaller subwoofers. This results in an undetailed or smeared acoustic image. The best 15-inch subwoofer will have the speed and transient response necessary to reproduce bass with phenomenal impact and realism.
  • Blend music seamlessly with full-range speakers. A good subwoofer needs to feel like it is an extension of your speakers without overpowering or drawing too much attention to itself. Combined with the best 15-inch subwoofer, your car speakers need to have clear and loud sound across the frequency spectrum. 

Types of Subwoofers

Powered Subwoofers 

Powered subwoofers are awesome. Ideally, this setup is an amplifier and a woofer in an enclosure. Since the specific amplifier in this setup is built-in, this subwoofer comes as one piece of equipment. Most powered subwoofers are compact and won’t require a lot of space in your vehicle. Powered subwoofers are very impressive; however, their smaller amplifiers and drivers may not provide the sound you want if you are looking for big bass.

Component Subwoofers

A component subwoofer is just the speaker itself. It will need to be mounted in a subwoofer box to produce quality sound. You will also need an external amplifier to power this subwoofer. Component subwoofers range between 8-inches and 15-inches in diameter. You can also find models that are specifically designed to operate in high or low power and in variable types of boxes.

Enclosed Subwoofers 

Enclosed subwoofers are pre-mounted to fit into a box that has specifically been designed to accommodate the subwoofer. Getting this kind of subwoofer eliminates the need to choose an ideal enclosure. However, on the downside, you will be limited by the number of box type shapes and speakers you have. You still need to install an external amplifier in your car to power this subwoofer.

Vehicle-Specific Subwoofers 

These are subwoofer types that are designed to fit in out-of-the-way locations in cars, SUVs, or trucks. They often come color-matched with the vehicle’s interior. Just like the powered subs, these subwoofers may not be your ideal choice if you are looking for big bass.

Best 15-Inch Subwoofer Pricing

  • Under $150: There are a variety of 15-inch subwoofers retailing at this price. However, most of the subwoofers in this price bracket will have low quality builds and sound quality. Depending on the manufacturing company, 15-inch subwoofers under this rate are popular due to their affordability and basic performance.

Key Features


If you are looking for a system that booms, there’s no substitute for big power. Make sure you check the subwoofer’s RMS power ratings and not the peak power ratings. The RMS rating is continuous power handling or the speaker’s output. They are a much more realistic measurement compared to peak max power. For quality, seamless sound, check the subwoofer power against your amplifier’s power output.

Frequency Range

Low frequencies are responsible for the bass output. Therefore, when comparing two subwoofers using this criterion, a subwoofer that has lower frequencies has the capability of producing more bass, assuming other factors such as the enclosure type remain constant.


A subwoofer’s sensitivity is measured in decibels (dB). This is the efficiency of a specific subwoofer to produce sound at a given power range. If you have a low-powered car stereo, getting a subwoofer with higher sensitivity is better, since it will require less power to perform. On the other hand, high-powered audio systems will work well with low sensitivity subwoofers. 

Other Considerations

  • Enclosure Type: Sealed boxes will produce the deepest and most accurate sound. However, if you are looking to get high volume, then the ideal enclosure is bandpass and ported subwoofer enclosure types.
  • Subwoofer Size: The size that plays the lowest and loudest is a never-ending argument in the car audio industry. Getting the loudest and lowest sound depends on a lot of things, including the sensitivity, enclosure type, and the available power. However, if your ultimate goal is to enjoy low and loud music and space isn’t an issue, then it would be advisable to buy the biggest subs. But do not underestimate small-sized subwoofers. If well-wired and installed in the right enclosures, they are capable of producing amazing sound from your car audio system.
  • Several Coils: Most vehicle owners pick DVC (dual voice coils) subwoofers over single voice coils. DVC subwoofers support flexibility when it comes to wiring compared to single voice coils. Most top-of-the-line, 15-inch subwoofers come with dual voice coils.    
  • Impendence: Most subwoofers have a 4ohm impendence. However, 2ohm, 8ohm, and dual voice coil subwoofers have become popular. When deciding on what subwoofer to buy, get one that matches up to your amplifier in terms of impendence and power rating.

  • Don’t install your subwoofers close to metal parts that are conducive to magnets. Setting up your subwoofer close to metals will affect its electromagnet. Instead, use wooden or non-magnetic material.
  • If you are new to installing car audio, it’s best to hire an expert or use the provided user manual. Most subwoofer manuals come with detailed information on installation and maintenance.
  • If you are installing your subwoofer by yourself, make sure all the wires are properly plugged into the right jacks. Wrong connections could cause a short or blow up your entire audio system.
  • Always install your subwoofers in spaces with adequate ventilation. Ventilation helps maintain your subwoofer’s durability.


Q: How much power do I need to power my 15-inch subwoofers?
