Earthquake i82SWS 8-Inch Shallow Under-Seat Subwoofers — 2 Ohm Pair for BMW

Experience punchy bass with the Earthquake i82SWS 8-inch shallow under-seat subwoofers

Earthquake Sound pioneered the shallow woofer system, delivering surprising low-end performance from tight spaces. The i82SWS pair is designed for 2-ohm automotive audio networks, making a straightforward upgrade for vehicles with under-seat woofers. The set is built to replace factory drivers beneath the front seats, often without major modifications. While BMW models are a primary target, the SWS family is adaptable to other compact spaces and aftermarket systems, offering a scalable solution for more engaging in-car sound.

Key specs and build features include a compact 2-1/8 inch mounting depth, an inverted cone for extended excursion, and a rugged NOMEX/ROMEX spider assembly. The pair handles up to 150 Watts RMS per speaker (300 Watts total max), providing a satisfying boost to low frequencies without a bulky enclosure. For best results, a sealed enclosure is recommended to keep bass tight and controlled.

Why this matters to your listening experience

In real-world driving, shallow depth drivers matter because they fit in cramped bundles behind seats, under consoles, or alongside flooring panels. The Earthquake i82SWS is designed to slot into those small spaces and pair with modern amplifiers that use 2-ohm loads. This combination can help you notice more rhythm in your music, the warmth of guitar tones, and the thump of cinematic cues without overwhelming your cabin with vibration.

• Compact depth for flexible placement and easy installs
• 2-ohm impedance compatible with many OEM and aftermarket amplifiers
• 150 Watts RMS per woofer (300 Watts total Max) for clear, controlled bass
• Inverted cone design for greater excursion in a shallow mount
• NOMEX/ROMEX spider assembly for durability and stability

What to expect in installation and setup: you can replace factory under-seat woofers with a precise fit that often requires no seat removal or only minimal disassembly. A sealed enclosure helps keep bass tight, while gaskets included in the kit assist with a clean seal between the woofer and mounting surface. As with any car audio upgrade, results will vary with your vehicle and head unit, but many users report a more engaging and balanced bass presence during daily driving and entertainment tasks.

For best results, consider pairing these woofers with a compatible amplifier and a properly sized enclosure. The i82SWS line is built to be a reliable bass partner in BMWs and other compact interiors, as well as a solid upgrade for a broad range of vehicles seeking more musical impact from existing audio systems.
