JVC designed their top-of-the-line Arsenal CS-AW8520 15" subwoofer for all you die-hard bass fanatics out there. This bass workhorse features just about every technological innovation JVC could cram into one sub, plus high-quality construction with advanced materials. Take the Kevlar® laminated hemp fiber cone, for instance — it's tough and rigid, but also extremely lightweight, so you'll hear nothing but true bass response. The Santoprene™ surround maintains linearity during long excursion for impressive accuracy.

Beat the heat
The sub's mammoth chassis features Thermal Transfer Technology for rapid heat dissipation — venting in the die-cast aluminum basket and the bottom plate keeps the sub's interior cool under fire. The double-stacked 308-ounce magnet features a heat-resistant resin cover for additional shielding. The removable trim ring covers up the sub's mounting holes for a sweet-looking installation.

Instant impedance switching
The CS-AW8520 features dual 2-ohm voice coils, and JVC's unique Rapid Fire Impedance Selector Terminal allows you to switch instantly between 1-ohm or 4-ohm total impedance to get the best performance out of your amplifier. JVC even incorporates fuses at the terminals to provide an additional layer of damage protection. You can feed this bass behemoth up to 1,500 watts RMS for the kind of low end you'll be thrilled to roll with.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Most mono amps are stable down to 2 ohms.

To drive this single subwoofer, we recommend a mono amplifier rated between 1125 and 2250 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.
