The current focus on neodymium subwoofers offers a wide range of sizes, numerous upgrade options, and different coil configurations. Whether you plan a powerful car audio setup with your VW Golf, Audi A4, BMW 3 Series, Mercedes C-Class, SEAT Leon, or Opel Astra: the customizable models from Fi Car Audio make car audio tuning much easier. In addition to top-class subwoofers, you will also find accessories such as amplifiers, cable sets, and connection terminals in the online shop. If needed, take advantage of the reliable installation service in Frankfurt (Oder) to have everything perfectly tuned or get advice on suitable products in advance from the Masori AI chatbot.
Fi Car Audio relies on complex cooling stages and inductance reduction for all its neodymium subwoofers. The series mainly differ in coil sizes, power handling limits, and designs of the centering spiders. In the car sound upgrade, they offer a compact design with high power density thanks to neodymium motors. For car audio enthusiasts who prefer maximum volume and deep bass, there are various options:
All models benefit from push terminals for thick speaker cables. D1 or D2 voice coils are available, allowing flexible adaptation to various amplifiers or impedance requirements. The dustcap can also be customized: in addition to a 6" or 7" carbon dustcap with a glossy finish, various colors of the Fi Car Audio logo are available, including almost all RAL color shades.
For optimal installation in the car, it is always recommended to use suitable amplifiers (e.g., depending on power requirements from 1000 W RMS up to over 5000 W RMS), stable cable cross-sections (at least 25 mm² or 50 mm²), and solid enclosure materials (e.g., MDF or multiplex). For precise sound, the enclosure volume should be tailored to the model. Equally important is sufficient airflow for the cooling stages so that the dynamic reserves of the subwoofers can be fully utilized.
| Series | Sizes (inches) | RMS power (W) | Spool Config | Spiders (Standard) | Application area |
|---|---|---|---|---|---|
| NEO 3.X | 12, 15, 18 | up to 2500 | D1 / D2 | 2–3 | Allround SQ & Level |
| NEO 3.5 | 12, 15, 18 | 1750 | D1 / D2 | 2 | Sound Quality & Daily Applications |
| NEO 3.7 | 12, 15, 18 | 2500 | D1 / D2 | 3 | Robust SPL & Everyday |
| NEO 3.9 | 12, 15, 18 | >2500 | D1 / D2 | 4 | Extreme SPL & High Pressure |
| NEO 4.X | 12, 15, 18, 21 | up to 4500 | D1 / D2 | 3–4 | Powerful & flexible concepts |
| NEO 4.7 | 12, 15, 18 | 3500 | D1 / D2 | 3 | Versatile (Bandpass/Reflex) |
| NEO 4.9 | 12, 15, 18, 21 | 3500–4500 | D1 / D2 | 4 | Port, 4th/6th Order |
| NEO 4.11 | 12, 15, 18, 21 | ≥3500 | D1 / D2 | 4 | Modern monster applications |
All models consistently use high-quality cable connections thanks to the screwed terminal blocks and push terminals. The cooling options range from a milled aluminum pole sleeve (first stage) to a curved compression cap (second stage) to massive aluminum fins (third stage). This allows inductance and thermal stress to be minimized individually.
For optimal integration into your car sound system, it is worth considering the sensitivity, frequency response, and preferred music genre. Especially in an Audi with factory-precise interior sound or a BMW that could use more deep bass punch, different enclosure types (for example, sealed boxes for precise transients or bass reflex enclosures for powerful low-end) are suitable. Plug & play solutions for VW, SEAT, or Opel also simplify the connection and reduce installation effort and space requirements.
If you want to further improve your car audio system, investing in damping materials for doors and trunk to eliminate vibrations is worthwhile. High-quality amplifiers with at least 1-ohm stable output power emphasize the level and maintain control over the subwoofer. Make sure all components have the correct power supply (e.g., AGM batteries or auxiliary batteries) as well as sufficiently thick power and ground cables.
For those seeking maximum flexibility, Fi Car Audio also offers the option to order the logo in almost any RAL color. It becomes even more personalized with various centering spiders and dustcap variants. Each upgrade option feature helps to customize the subwoofer to personal preferences – whether you're aiming for SPL competitions or prefer to enjoy deep bass in everyday life.
The path to perfect car sound leads through a well-thought-out concept, starting with the choice of the right subwoofer, suitable amplifiers, cable sets, and subsequent installation. Thanks to the wide range of Fi Car Audio models and the continuously growing portfolio in the Masori car audio online shop, you are sure to find a solution here that fits your vehicle and takes the bass in your Audi, VW, BMW, Mercedes, SEAT, or Opel to a new level. With the experienced expert support and the installation service in Frankfurt (Oder), the installation is safe and smooth.

Diese kleinen Superhochtöner halten Einzug in die Welt der High-End Lautsprecherboxen. Mit dem kristallklaren Sound eingesetzt ab 10.000Hertz bringen sie, sowohl frontal als auch rückwärtig eingesetzt, einen ungeahnten Glanz in jede Aufnahme. Mit geänderter Weiche sind sie zu 100% empfohlen.
Also Verarbeitung ist super und der kleine hat richtig wumms
Super Produkt, sehr flexibel und bleibt auch sehr gut
Preis Leistung super
Ich habe mir den bestellt weil ich ihn bei mein Kumpel im Auto gehört habe und ich sehr zufrieden damit bin. Nach der Bestellung hat es 2 Wochen gedauert bis er da war. Ganz schöner oschi 😄 der auch einiges an Gewicht mit sich bringt.
Lots of clean power!! I will be running it at 1ohm, tuned by the M8.14 dsp amp that I also purchased from Masori. It's going to push my subs hard with musical precision!! Everything I have purchased at Masori has arrived in pristine conditon, packed incredibly well for safe shipping. Excellent shopping experience!!
These are amazing. I replaced my stock speakers with 1 in each of the four doors of my truck. Make sure you sound deaden your doors first. The mid-bass is INCREDIBLE!!!
5 Star Subwoofers!! I bought 2 of the 2ohm version. They will be run in parallel down to 1ohm, which will make my Audison SR1.500 shine. Perfect in a sealed box if you like a kick in the back!!
This amplifier is going to be the brains behind the whole system. It has a 8 amplified channels and a 14 channel dsp. It will provide the proper tuning to an external 4 channel amp, as well as the mono block for the subs. it arrived quickly and in pristine condition!!
Everything is okay, for Mazda MX5 2010
