SB-HY-SON/12W3v3: Stealthbox® for 2010-Up Hyundai Sonata

Hyundai's Sonata offers outstanding value and refinement, giving many luxury cars a good run for their money. As great as the Sonata is, the factory sound system can definitely benefit from a serious upgrade in the bass department.

Our Stealthbox® for the Sonata features a robust JL Audio 12-inch subwoofer housed in a compact, sealed, fiberglass enclosure which fits neatly into the passenger side rear corner of the trunk. The form-fitting design conserves your valuable trunk space while still permitting full access to the spare tire. A clean-looking steel mesh grille protects your investment from loose cargo.

With the unmatched clarity and output of an enclosed subwoofer system built and tuned specifically for your vehicle, you're sure to look forward to each turn of the key.

The Hard Data: Contains one 12W3v3-2 subwoofer in a sealed enclosure. 500 watt power handling. Wired for 2 ohm mono. A steel mesh grille is included.

"If you're lucky enough to have a vehicle that one of these Stealthboxes is made for, choosing it over anything else we have heard or seen is a no-brainer."

– CarSound Magazine

"...I was only hoping for more bass to the tune of what the factory Shaker 1000 system offered. What the JL Audio Stealthbox delivered was performance that surpasses the factory Ford stereo systems so completely that you can’t even compare the two systems."

– Shane McGlaun, I4U News, November 2010... on the Ford Mustang Stealthbox
