Loaded Car Subwoofer Boxes

Skip the guesswork and get straight to the bass with 12 Volt Outlet's selection of loaded car subwoofer boxes — factory-matched enclosures with subwoofers already installed, tuned, and ready to pair with your amplifier right out of the box.

A loaded subwoofer enclosure takes the work out of building a sub box. The manufacturer has already matched the right subwoofer — or multiple subwoofers — to a purpose-built enclosure optimized for that specific driver's parameters. The result is a plug-and-play bass solution that sounds better than most custom builds put together by someone guessing at box volume and tuning frequency — because the manufacturer did that work for you at the factory.

Available in sealed enclosures for tight, accurate bass and ported enclosures for maximum output and deep low-end extension, loaded subwoofer boxes come in a wide range of sizes and configurations to fit trucks, SUVs, sedans, and custom installs. Single-subwoofer and dual-subwoofer loaded boxes are available, with terminal cups and wiring ready to connect directly to your amplifier's speaker outputs.

Loaded enclosures are an excellent choice for anyone who wants a clean, professional-looking install without custom fabrication — and the confidence of knowing the subwoofer and box were designed to work together from day one.
