Best 8 Inch Subwoofer Car Audio Buyers Guide

An 8-inch subwoofer is an ideal choice for those who want to upgrade their car, boat, or home audio system without over-expending, and they pack a great punch that is more than enough for the majority.

Please know that all the reviews focus on the speakers. Take into consideration the enclosures you need and the proper wiring to connect with your car stereo and amplifier.

The average sub adds some serious kicks to any type of genre. Remember to select the sub that matches your car’s audio system as a whole for maximum efficiency and durability.

What to look for when choosing an 8 inch subwoofers?

Larger subwoofers are speakers focused on reproducing low to medium frequencies. In contrast, car speakers are small and do not have the technology to reproduce enough low-frequency sound to provide you with an intense bass.

A quality sub improves your overall listening experience. Here are some ideas of what to look for when choosing the best 8 inch sub:

Frequency response

Frequency response is an audible periodic vibration measured in hertz. Sharper signals are related to higher frequencies. On average, most people can hear tones in the frequency range of 20 to 20,000 Hz.

Subwoofers capacities vary but are overall capable of producing 20 to 200 Hz. It is recommended to limit the range of a subwoofer from 100 Hz downwards by using a crossover filter.

RMS power rating

The RMS power is the amount of power that the subwoofer handles. This means that they can produce more output if they handle more power, almost always aided by an amplifier. Always go with the recommended power range according to the amplifier’s output capabilities.

Better sound quality

Great sound quality does not rely entirely on the subwoofer. You need to consider size, power, and frequency range. The type of enclosure, the sub’s location in the vehicle, and the type of amplifier you use can make a huge difference in the quality.

Mounting depth

Make sure you follow the manufacturer’s recommended enclosure size, especially if you don’t have much room. The box volume will indicate the size of your enclosure for proper performance.

Ideally, you determine the minimum depth of your box by adding 2 inches to the subwoofer’s depth. Shallow mounting depth is recommended for replacing your car’s factory speakers placed in tight spaces.

Enclosure type

A strong, tightly-constructed enclosure is what gives subwoofers their optimum performance. Without one, these cannot deliver great sound because the performance from the back cancels out the bass frequencies coming from the front of the speaker.

The ported enclosure volume tends to be the preferred choice for bass lovers. You can get more bass with a hassle free installation. Of course, this depends on how much power the car’s sound systems will require.

The enclosure range from:

  • Sealed boxes for deep, accurate bass
  • Ported boxes to reinforce bass response
  • Bandpass boxes for maximum kick or extra loudness
  • Free-air woofers for an isolated performance from the back of the unit
  • Underseat enclosure for those vehicles with no trunk space

Sensitivity rating

The sensitivity rating is the sound generated by the loudspeaker (dB), generally 1 (W) of power at 1m (meter). The higher the sensitivity rating of a speaker is, the louder it plays at a certain amount of wattage.

Types of voice coils

Inside of an subwoofer by Pioneer

Single voice coils

Individual voice coils are the most common coils. These are wound in one direction around the cone.

Each winding is so tight that the coil leads touch. A single voice coil is easy to identify because it has only one pair of speaker wire entries.

Dual voice coils

Dual coils are wound in opposite directions. Winding posts in the rear help represent DVC speakers.

These speakers generally handle higher power; they are more versatile in impedance settings when connected in series or parallel with other speakers.

Subwoofer 8 Inch FAQ

As a newcomer to the world of subwoofers, we understand that you may have common questions about the speaker. We compiled the frequently asked questions for your convenience.

Should I get a specific enclosure?

Indeed, you need to get a specific enclosure to get the most out of your subwoofer. The quality and the performance of your subwoofer depend on a tightly-constructed enclosure that is strong enough to hold serious sound kicks.

Just purchase a pre-made enclosure to fit your subwoofer unless you are a highly-talented craftsman with a deep understanding and experience of enclosure volumes and sizes.

Refer to your manufacturer’s manual to know which enclosure your subs need: sealed, ported, or bandpass.

Do I need an amplifier for my 8 inch subwoofer?

Subwoofers are engineered to reproduce sounds located at low frequencies, and this takes a power source, meaning an amplifier.

An amplifier allows the subwoofer to work at its best by providing the kind of power it needs to reproduce its maximum sound output and deliver a deep bass.

If you can’t buy an amplifier, you are still able to connect the speaker without an amplifier, depending on the subwoofer type. Just keep in mind that it involves a deeper knowledge of sound systems, and the sound quality is never the same.


Upgrading your car sound systems is a serious business that requires proper knowledge to make the best out of your hard-earned investment. If you don’t need a lot of basses, get 150 watts to start up. Or simply get an under-seat subwoofer that can produce enough bass for your needs.

Getting 8 inch subwoofers depends on your budget, taste, type of car, and many other variables that you must understand. Quad voice coils are just what you need for a wide low-frequency response.

There’s no other sound better than a properly set up subwoofer that’s part of a complete sound system. Not all subwoofers are created with the same specs, and the price is not always the right choice.
