Buy car subwoofer in the Masori online shop – Noticeably more bass for your car
A good car stereo and high-quality speakers are known to be the foundation, but without a subwoofer, every sound system lacks depth. Because only a subwoofer brings the frequencies into play that you not only hear but feel with your whole body. Whether you love hip-hop, electronic, rock, or classical music, a well-tuned car subwoofer gives your music power and emotion.
On this page, you will find all common types:active subwoofers with built-in amplifier, passive models for flexible systems, complete sets with all accessories as well as vehicle-specific solutions, which fit into your car without major modifications. We show you what really matters.
Why a powerful car subwoofer is a real upgrade
Most factory-installed speakers are designed for everyday use and cost optimization. They often cover mid and high frequencies well, but are weak in the low-frequency range. Without a subwoofer, the music sounds flat, voices stand “naked” in the room, and beats lose their energy.
A good subwoofer solves this problem by taking over the low frequencies. This relieves the door speakers, which can then play clearer and cleaner. At the same time, you get the “cinema feeling” in the car: bass drums have punch, electronic drops roll through the vehicle, double basses sound full and authentic.
What types are there?
Active car subwoofers
An active subwoofer is the quickest solution. It already has the amplifier built in, so you just have to connect it. Perfect for beginners, company or leased cars, and for anyone who wants noticeably more bass with minimal effort. Especially popular are under-seat models, which take up hardly any space and can be integrated inconspicuously.
Here’s the link to the active car subwoofers.
Passive car subwoofers
A passive subwoofer requires a separate amplifier. In return, you have maximum flexibility: you can freely determine power, impedance, and sound character. If you want to expand or individually tune your system later, this is the best choice. This also applies to ambitious listeners who value high durability and upgrade options.

Vehicle-specific models
Not everyone wants to make major modifications to their car. That’s exactly why there are vehicle-specific subwoofers. These solutions are developed precisely for certain models. That means: perfect fit, OEM look, and a clear gain in bass without your vehicle losing originality.

Sound, size, and enclosure – what really matters
An 8-inch subwoofer sounds fast and precise, a 12-inch is the versatile all-rounder, and a 15-inch provides noticeable depth. But size alone is not decisive, because the enclosure makes up at least half of the sound.
-
Sealed: crisp, precise, for music lovers who value control.
-
Bass reflex: more deep bass and efficiency, the “fun maker” among enclosures.
-
Bandpass: solid pressure in a specific frequency range, popular for maximum show effects.
Watts, ohms, and frequency – technical data for more transparency
If you plan to upgrade your car sound system, you need to keep an eye on power (RMS), resistance (impedance), and frequency range. Only with the right sizing does a subwoofer develop its maximum efficiency:
-
RMS power: Values from 300 to 1000 watts RMS are popular for many music genres. Those who like it louder choose high-end variants with 1500+ watts.
-
Ohm value: With 2-ohm or 4-ohm models, you find flexible options. Adapt them to your amplifier for optimal performance.
-
Frequency spectrum: Subwoofers that transmit from 20 Hz provide particularly noticeable bass, while models with a higher cutoff frequency harmonize well especially in compact vehicles.

Music genres & bass preferences – which subwoofer suits your style?
Not every subwoofer sounds the same and not every genre demands the same. Your musical taste is therefore an important factor when choosing size and enclosure type:
-
Hip-hop & EDM: For rich drops and powerful beats, a 12-inch subwoofer in a bass reflex enclosure is recommended. Here you get the strong, deep bass that brings modern club sounds to life.
-
Rock, pop & metal: Fast guitar riffs and driving drums benefit from a 10-inch variant that scores with tight bass contour and clean timing.
-
Classical & acoustic music: Those who value naturalness choose an 8-inch subwoofer in a sealed enclosure. This way, double basses and low strings are reproduced realistically and controlled.

The choice of brand can also be decisive:
-
Deaf Bonce – known for extreme power and brutal deep bass, perfect for SPL competitions and anyone who wants maximum volume.
-
DD Audio – stands for uncompromising sound and precise craftsmanship, ideal for listeners who value detailed, powerful bass.
-
Ground Zero – one of the leading manufacturers in the car hi-fi sector, with an enormous range from everyday subs to high-end SPL machines.
-
Focal – premium brand from France, world-renowned for detailed, audiophile sound quality and finely tuned systems.
-
Audison – high-end for demanding listeners, especially strong in the SQ area with highest precision and linearity.
-
Hifonics – traditional brand, popular for lots of power at a fair price – strong bass with high fun factor.
Everyday use, comfort, and installation
Many drivers don’t want to sacrifice half the trunk to create a better music experience. That’s exactly why there are shallow enclosures or subwoofers in the spare wheel. These are professional solutions that combine everyday usability with real sound gain. Those who regularly load their car fully benefit especially. A real win-win situation!
For ambitious listeners, a custom box for more volume is recommended. These models are precisely tuned and thus offer maximum performance. Placement is also crucial and significantly influences the sound. Therefore, you should carefully consider whether you want to position the subwoofer in the trunk, on the back seat, or even under the seat.
Our tips for installation & tuning in the car
A subwoofer only unfolds its full potential when it is properly installed and tuned. Even small adjustments can make the difference between “lots of bass” and “good sound.”
-
Set crossover frequency: Choose low-pass between 70–90 Hz, and high-pass for the front system accordingly. This way, subwoofer and speakers blend harmoniously.
-
Set gain control cleanly: Adjust the level so that sub and front system play in balance. Too much gain causes distortion.
-
Check phase: If the bass sounds thin, a phase reversal can immediately provide more punch.
-
Use bass boost sparingly: It can add extra punch, but don’t overdo it to avoid overload.
-
Consider damping: Damping doors and trunk increases precision and prevents annoying rattling.
-
Secure power supply: A good cable set is mandatory; for large systems, additional batteries or an alternator upgrade help.
-
Use DSP: Digital sound processors provide fine tuning, better linearity, and a realistic soundstage.
If you're unsure, the experts at Masori will help you with fine-tuning. This way, every detail is perfect and your car hi-fi system sounds just as it should.
Typical scenarios
-
Compact car: Active under-seat sub, quick to install, noticeable added value.
-
Family car: 12" sealed with separate amplifier, practical and musical.
-
Sporty coupe: 12" bass reflex, clear deep bass with punch.
-
SPL show car: 15" or multiple subs in bandpass, powerful amplifier, massive power supply.

To summarize
A car subwoofer is the heart of any car hi-fi system. It makes the difference between 'just listening to music' and 'truly immersing yourself'. At Masori, you'll not only find a wide selection, but also suitable solutions for every need: from quick plug & play to individually tuned high-end systems.
