Discover our selection of car audio subwoofers: 16 cm, 20 cm / 8", 25 cm / 10", 30 cm / 12", 38 cm / 15", 46 cm / 18" and very large diameters. From compact subwoofers to SPL models with several thousand RMS watts for the most ambitious installations.
The car subwoofer is designed to
reproduce low frequencies. It complements
door speakers by adding depth, impact
and energy to the lower end of the spectrum.
Whether you are simply looking for more bass,
a balanced Hi-Fi system, an SQL music installation
or a high-power SPL project, the choice of subwoofer
must be consistent with the enclosure, amplifier,
impedance, and the vehicle's electrical system.
There is no single ideal diameter or power rating for all cars. The available space, enclosure volume, amplification power and desired sound result must all be considered together.
The diameter notably influences the available cone surface area, but it does not alone determine the depth, power, or quality of the bass.
Small subwoofers are interesting when space must remain limited. They allow you to create compact systems while still providing genuine bass reinforcement.
The 25 cm subwoofer is an excellent compromise between cone surface area, space requirements, and performance. It is available in both compact and Hi-Fi as well as high-power models.
The 12-inch is one of the most popular formats in car audio. The available choices are very broad: musical bass, high excursion, SQL, or SPL subwoofers with several thousand RMS watts.
With a large cone surface area, the 15-inch is very common in installations seeking more air displacement, depth and acoustic pressure.
The 18-inch is generally aimed at projects with a substantial enclosure volume. It is notably found in SQL, demonstration, and SPL installations at very high power.
Very large diameters are intended for specific projects capable of accommodating their enclosure volume and cone surface area. They require a complete study of the enclosure, amplification, and power supply.
Increasing the diameter increases the cone surface area,
but the final result also depends on excursion,
motorization, electro-mechanical parameters,
the enclosure, and the power actually available.
An excellent 10 or 12-inch subwoofer in a properly
designed enclosure can deliver a result significantly
superior to a large subwoofer installed in a poorly
matched enclosure.
The collection covers both small subwoofers intended for bass reinforcement and SPL models capable of handling several thousand RMS watts.
RMS power mainly represents a power handling capability. Efficiency, excursion, cone surface area, motorization, the enclosure and the power actually applied strongly influence the level and type of bass obtained.
To size an installation, mainly use
the RMS ratings provided by the manufacturer.
MAX or Peak values should not be considered
equivalent to continuous RMS power.
The amplifier must also be compared at the correct
operating impedance.
The choice of coils is essential to obtain the final impedance suited to your amplifier.
A single-coil subwoofer has a single coil with a given impedance. Its wiring is simple, but it offers fewer combination possibilities than a dual-coil model.
A dual-coil subwoofer allows you to wire the two coils in series or parallel. D1, D2, or D4 versions thus allow you to obtain different loads depending on the number of subwoofers used.
A dual 2-Ohm subwoofer is not simply
a "2-Ohm" subwoofer. Its two 2-Ohm coils
can be wired in series or parallel,
providing different load possibilities.
With multiple subwoofers, the combinations become
even more numerous. The final impedance must always
remain compatible with the amplifier's stability.
Before purchasing, determine the number of subwoofers, their coils, and the desired final impedance. This then allows you to select an amplifier capable of providing the power necessary for this precise load.
The enclosure is an essential part of the system. The same subwoofer can behave very differently depending on the volume and type of enclosure used.
A sealed enclosure has no port. Depending on the subwoofer and the volume chosen, it can offer a compact solution with a smooth and controlled response.
Bass Reflex uses a tuned port. The enclosure volume, the port surface area and its length notably determine the system's tuning frequency.
Bandpass places the subwoofer in an architecture comprising one or more chambers. Its behavior depends heavily on the design and the chosen tunings.
Competition or demonstration projects may require specific enclosures calculated according to the subwoofers, the desired frequency, the vehicle, and the available power.
The net enclosure volume must account for the
subwoofer's displacement, the port, and any reinforcements.
In Bass Reflex, changing the port surface area or length
changes the system's behavior. There is therefore no
universal volume or tuning valid for all
subwoofers of the same diameter.
For a more technical installation, the electro-mechanical parameters allow you to better understand the speaker's behavior and simulate different enclosures.
Fs corresponds to the resonance frequency of the speaker in free air. It constitutes useful data, but does not alone allow you to determine the bass obtained once installed.
Qts combines the electrical and mechanical quality factors. It is used with the other parameters to analyze and simulate the subwoofer's behavior.
Vas is related to the flexibility of the speaker's suspension and is used in the calculations and simulations of acoustic loads.
Xmax gives an indication of the cone's linear displacement capability. It must be considered with the cone surface area, power, and the overall design.
The final behavior depends on the complete subwoofer, the enclosure, its tuning, the cabin, the filtering, and the applied power.
The amplifier must be chosen according to the desired RMS power and, above all, the system's final impedance.
Class D monoblock amplifiers are very common
for powering car audio subwoofers.
They are available in a wide range of power ratings
and with different nominal impedances.
An amp rated at 2000 W RMS at 1 Ohm
does not necessarily deliver the same power
at 2 or 4 Ohms. Therefore, you must always compare
the power to the load actually used.
As power increases, the electrical system of the vehicle becomes an essential part of the project.
The cable gauge must be sized according to the current, length, and installation. High-power projects require gauges significantly larger than a standard installation.
The positive cable must be properly protected. The fuse is intended to protect the cable against excessive current in the event of a fault or short circuit.
A high-power installation may require more electrical capacity, with a battery suited to the project and operating voltage.
For very high-power installations, the alternator's charging capacity must also be taken into account in order to properly maintain the electrical system.
The low-pass filter limits the higher frequencies
sent to the subwoofer to ensure a coherent
transition with the other speakers.
Depending on the enclosure type and installation,
a subsonic filter can also be used
to limit unwanted very low frequencies.
Frequencies and slopes must be adapted
to the system, enclosure, and subwoofer.
Before buying, check the entire project. A subwoofer must work as a system with its enclosure and amplification.
For an installation focused on sound quality, look first and foremost for good integration with the rest of the system, a properly sized enclosure and a coherent setup.
An SQL project seeks a lot of volume while maintaining musical use. Displacement capacity, efficiency, the enclosure, and amplification become essential.
SPL projects aim for high acoustic pressure. They can use high-power subwoofers, large cone surfaces, and enclosures designed for the vehicle and the desired frequency.
To simply improve the bass in a car, it is not necessary to look for several thousand Watts. A well-chosen and well-installed subwoofer can already transform the listening experience.

The choice depends on the available space, the enclosure and the desired result. 8 and 10 inches allow for compact installations, 12 inches is very versatile, while 15 and 18 inches offer more cone surface for large projects.
No diameter is systematically better. The right choice depends on the subwoofer itself, its enclosure, the amplification, the available space, and the sound goal.
It depends on the desired level and the available amplification. For a daily installation, a few hundred Watts can already be effective. SQL and SPL projects may require much higher power.
D2 generally refers to two 2-Ohm coils, while D4 corresponds to two 4-Ohm coils. Their wiring allows for different final impedances.
First determine the number of subwoofers, the coil type, and the desired final load, then choose an amplifier stable at this impedance.
Both architectures can deliver excellent results. The choice depends on the subwoofer, the available volume and the desired behavior. A Bass Reflex uses a tuned port, unlike a sealed enclosure.
There is no universal volume according to the diameter. Two 12-inch subwoofers may require very different volumes. Check the recommendations or technical parameters of the model concerned.
You must compare the RMS power actually delivered by the amplifier at the subwoofer's final impedance. An amp does not necessarily offer the same power at 1, 2, and 4 Ohms.
Yes, if the final wiring impedance remains compatible with the amplifier and if it has power suited to all the subwoofers.
No. The rated power does not directly translate into a proportional increase in sound level. Cone surface, excursion, efficiency, enclosure and actually applied power also play a role.
It depends mainly on the amplifier's consumption and the capacities of the vehicle's electrical system. High-power installations may require battery, wiring, and charging upgrades.
It is generally a subwoofer designed to withstand heavy demands and participate in an installation seeking high acoustic pressure. Its design and use can be very different from a subwoofer intended solely for discreet bass reinforcement.
