The JL Audio Stealthbox is one of the most sought-after enclosure subwoofer models for car audio enthusiasts who aim for noticeably stronger bass reproduction in their vehicle. This concept enables impressive bass with minimal space requirements. Typical materials such as fiberglass (GFK) and wood ensure a robust and shape-stable enclosure that is precisely tailored to the contours of various car models. Brand enthusiasts benefit from perfectly adapted solutions in vehicles from BMW, Mercedes, Audi, VW, SEAT, or Opel. In particular, plug & play variants make installation easier, allowing both technically interested individuals and professionals to achieve quick results.
The precise development through laser scanning and solid modeling technology optimizes the interior volume utilization in every model. This results in powerful bass performance without unnecessary loss of trunk space. The following parameters are noteworthy in many JL Audio Stealthbox versions:
These features minimize distortion and ensure a rich bass that supports the rest of the car sound system. With a suitable amplifier, users can further precisely adjust the sound character.
JL Audio offers a variety of Stealthbox versions for different vehicle models. One example is the SB-B-X5/10W1v3 for the BMW X5, which delivers powerful bass with 600 watts RMS for long distances. Also very popular is the SB-VW-GTI/10TW3 for the VW Golf GTI, which can handle a proud 400 to 800 watts RMS thanks to a TW3 subwoofer and can be perfectly integrated into the trunk. Solutions also exist for smaller cars like the Smart fortwo, such as the SB-SMRT-4-2/8W3v3. This usually has a power handling capacity of 250 to 500 watts RMS. In all cases, the product comes pre-covered, so it blends seamlessly into the interior.
| Model | Subwoofer type | Watt RMS | Compatible Vehicles | Installation position |
|---|---|---|---|---|
| SB-B-X5/10W1v3 | 10"-Woofer (W1) | up to 600 W | BMW X5 | Trunk, driver's side |
| SB-VW-GTI/10TW3 | 10"-Woofer (TW3) | 400–800 W | VW Golf GTI | Trunk, side |
| SB-SMRT-4-2/8W3v3 | 8"-Woofer (W3) | 250–500 W | Smart fortwo | Behind the front seats |
Especially with these compact stealth box systems, the built-in fiberglass enclosure is crucial for stable sound radiation. The frequency response usually ranges from 25 Hz to 200 Hz, guaranteeing a powerful kick bass. Additionally, a 2-ohm or 4-ohm variant is often available to make the amplifier connection as flexible as possible.

Sehr Zufrieden
Habe diesen Hochtöner in meine Soundboks Go eingebaut. Ein bisschen zurechtbasteln des vorhandenen Hochtönergehäuses, und voila! Absolut genialer kristallklarer Sound! Kein Vergleich zu vorher. Nun kann die kleine Go in puncto Lautstärke und Klang selbst mit der SB4 mithalten (wurde natürlich direkt von mir gleich ausprobiert :D )
Bester und effizientester Hochtöner für alle, die vorhaben, ihre akkubetriebene Bluetoothbox zu pimpen :)
Quality Product
Mega Set zu Mega Preis absolut begeistert.
Top power, nice remote
Small and potent
The amplifier is nicely small. It fit well behind the Vectra glove compartment. It provides good power compared to the heat unit own amplifier.
Product ok, delivery in 12 days.
Eingebaut in A-Säule, Klanglich sehr schön, Pegelfest. Bin zufrieden.
