Fi Car Audio manufactures high-quality car audio subwoofers in Las Vegas, with steel components made directly in the USA. 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.
Deze versterker is heeft hoog vermogen 9500rms,
En het geluid is zuiver,
Stroom verbruik valt mee gelukkig.
Goede aankoop gedaan.
Nette preise,gute lieferung ins ausland, alles klar- spitze!!
Bonjour, j'ai également besoin d'un caisson de basses.
vibe powerbox65.4m v7 samen met quadlock connector besteld.
Levertijd prima in orde.
vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.
Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
Geometrisch flach, spielt tief
Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.
Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.
Sehr geile Lautsprecher,laut und trotzdem klanglich megga geil.
Great addition for anyone adding door speakers.
After looking at many reviews, this was rated better than the alpine transporter t6 speakers.
Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,
Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
BELLISSIMO E FORTISSIMO
