2006 - Up BMW 3-Series (E90/E92) Sedan (4-Door) & Coupe (2-Door)
The JL Audio BMX 3-Series Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.
Construction: Stealthboxes are hand-crafted from fiberglass and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of enclosure rigidity and dimensional stability not possible with other enclosure materials, allowing wall thickness to be reduced compared to a typical wood enclosure. This gives you more interior box volume for a given external volume. Fiberglass and AMC materials are very strong and can be molded into very complex shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly into tight spots and minimize intrusion into your vehicle's useful space. Each Stealthbox is laminated, ground, joined, and finished by hand in the USA. Proprietary techniques and materials developed by JL Audio through years of fiberglass manufacturing experience ensure consistent quality and performance.

2006 - Up BMW 3-Series (E90/E92) Sedan (4-Door) & Coupe (2-Door)
The “Ultimate Bass Machine” is ready for your 3-series.
BMW’s audio systems have come a long way in the last few years, but they still lack in the low frequency department. The underseat factory woofers are small and can only do so much. If you’re seeking a real sub-bass solution with powerful output, excellent balance and impressive low-frequency extension, this Stealthbox® was made for you. Our 3-Series Stealthbox® design puts our patented low-profile TW5 subwoofer technology to excellent use, housing two 13.5-inch drivers in a sealed fiberglass enclosure with individual driver chambers. You’ll have plenty of trunk space to spare... enough to fit a couple of golf bags or luggage for a long road trip. And with the sound quality this Stealthbox® delivers, you will enjoy every mile on those road trips.
THE HARD DATA:
Contains two 13TW5-3 subwoofers in a sealed enclosure. 1200 Watt power handling. Wired for 3 ohm stereo (two individual 3 ohm terminals), can be wired as 1.5 ohms mono. Installs in the trunk against the back of the back seats. On vehicles equipped with folding rear seats, the enclosure will prevent access between the trunk and cabin.
