Want killer bass without giving up your whole trunk? This NVX loaded subwoofer enclosure is custom-made to fit perfectly in the right side of your 2017-2021 Honda Civic Hatchback. It comes with a powerful 10-inch SMW10D4 sub already installed in a hand-laid fiberglass box – so it's durable and sounds amazing. Handles 350W RMS (700W peak) and hits those low notes cleanly from 25 to 350 Hz. The sub has a carbon fiber-reinforced cone, butyl rubber surround, and a 2-inch voice coil for reliability. It's wired to a 2-ohm load, making it efficient with most amps. Installation is straightforward, and it tucks away neatly, leaving most of your cargo space free. If you're craving deeper, punchier bass without a custom build, this is your plug-and-play solution. Turn your Civic into a rolling concert!
