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?

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 an the best 8 inch subwoofer:

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 frequencies from 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.

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.

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 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

Polypropylene cone

This type of cone is what most of the subwoofers in the market are made. It provided a full sound quality and is capable of reproducing any type of sound, depending on its assembly and power.

This type of cone is humidity resistant and is composed of a plastic that is pressed yet flexible to keep over excursions and avoid breakage.

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 8 inch subwoofer by PioneerVoice coils are the windings around the cone of a speaker.

When current from an amplifier is coupled to the coil, a small magnetic field is formed. The magnet surrounding the coil opposes this field, driving the horn back and forth in a piston motion.

Without voice coils, modern speaker design would not be possible.

There are a few different coils, mainly related to the different winding methods and different materials of the coil.

Copper coils

Copper is the most common material for making voice coils.

It is a naturally abundant material and easy to work with due to its malleability. It is also an outstanding conductor and is widely used in speaker cables, AC power (Alternating Current) wiring, and interconnects for audio/video equipment.

Typically, the copper coil is coated with a polymer sheath and an adhesive coating. Copper handles heat exceptionally well and is suited for high power handling applications.

Kapton coils

Kapton is essentially a plastic material; it is wrapped with fiberglass resin to increase its thermal handling.

Modern Kapton coils perform high when faced with high operating temperatures. Kapton coils often withstand better under thermal stress than the former wraps around. This is in stark contrast to the original versions of Kapton brackets, which often melt under high-temperature stress circumstances.

Aluminum coil

Aluminum coils are cheap. They act as excellent thermal conductors. This can be detrimental from a power handling perspective, as the heat exposed to aluminum transfers very well to this element.

Consequently, the adhesives used to assemble the horn tend to disintegrate more quickly. This is why an aluminum voice coil is suitable for tweeters and ribbon horns that require less power to move due to being extremely light.

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.

Difference between component or non-component

There are subtle yet important differences between the two of them.

Installation

Component speakers use separate tweeters, crossovers, and woofers to reproduce a loud sound. In comparison to the non-component system, you need to invest time and effort into installing these speakers.

Sound quality

Without a doubt, the use of a couple of tweeters, subtweets, and other tools, this system reproduces a clear sound.

The non-component speakers are unable to put out a good bass and are of bad quality.

Power handling capacity

One of the main differences between these speakers is that the latter is designed to handle up to 250 watts of peak power and 110 watts of RMS power.

Different between 2ohm versus 4ohm subs

There’s no rocket science in this subject: car audio subwoofers have either 2 and 4 ohms impedance.

These speakers are usually connected to enhance the amplifier power output. Commonly, car owners connect two 2 ohm subwoofers to create a 4-ohm load on the amplifier.

Either option is acceptable. However, the bass you get t is determined by this option.

If you want a moderate volume bass with the highest quality, then a 4-ohm subwoofer will be your choice.

A 2-ohm rating doesn’t have much resistance in its circuit. Plus, the amplifier can feed the subwoofer with more power without much resistance. So, since the resistance is less, the subwoofer is louder.

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 depends 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, bandpass.

Do I need an amplifier for my 8 inch subwoofer?

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

An amplifier allows the subwoofer to perform 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 system and the sound quality is never the same.

What are the best settings for my 8 inch subwoofer?

Here are a few basic guidelines for your subwoofer:

Begin with your speaker level

Distorted signals can destroy speakers, subs, and eardrums, and it interferes with the sounds of musical instruments.

If you decide to power your subs with an amplifier, make sure that the amp’s gain is properly tuned to prevent distortion.

Play some tunes and turn up your receiver’s volume until you hear the sound distorting; then, lower the volume until the music sounds clean again. Take note of where the receiver volume is when there is no distortions happening.

Open the low-pass filter and flatten the signal

Turn the subwoofers amp’s knob to its lowest, most counter-clockwise position.

Switch the low-pass filter on and point it as high, clockwise, as it can be.

Turn off the bass knob all the way down.

Reset the remote control to a middle position. After this, you will now have the choice of boosting or cutting the bass on depending on the song.

Change the receiver’s bass tone to its middle, zero, or “flat” setting. If it has a subwoofer level control, program it to “no gains” or middle.

Make sure that you turned off the crossover, low-pass filter, or boost on the subwoofer output.

As a general rule, low-pass filters, crossovers, or bass boosts on the receiver and the amplifier are not met to be used all together. Pick one or the other to avoid phase distortion.

Adjust the bass and subsonic filter

Carefully turn up the bass knob to drum sound likeness.

Bass boost is where distortion comes in, so be careful. If present, lower the sub amp’s gain until it goes away.

If you have ported subwoofers, use a subsonic filter to counter overly loud low notes and help decrease the note levels at which the enclosure resonates.

By fine-tuning all the filters, your bass drum sounds should be dry or loose, depending on your preference.

Match the receiver volume and the subwoofer level

Start by turning up the receiver’s volume to a maximum, distortion-free position. Then, begin to slowly turn up the subwoofer amp’s gain until you recognize that the bass sounds balanced in comparison to the rest of the music.

Summary

Upgrading your car sound system 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 bass look for 150 watts to start up.

Having the best 8 inch subwoofers depends on your budget, taste, type of car, and many other variables that you must understand. Make sure that the woofer has 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.
