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. Check the loaded enclosure’s impedance, RMS power requirements and installation dimensions before pairing it with an amplifier.

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.

This collection includes products from SoundQubed, Audiopipe, VIBE Audio, Massive Audio and DS18. Compare the exact listing for specifications, included components and installation requirements.
