Sold by AudioSellerz.com

The Sky High Car Audio FE Series 15" Subwoofer is the big dog of the FE line—a 700W RMS 15 inch car audio subwoofer built for real-world daily abuse, deep low-end extension, and serious output without premium-level pricing.

Like the 10" and 12" FE models, the FE 15 uses a 2.5" 4-layer high-temp voice coil and is rated at 700 watts RMS, giving you strong thermal handling and motor control in a daily-driver friendly package. These larger FE models also step up to a double-stacked ferrite motor and upgraded push terminals for secure, high-current connections in bigger systems.

Available in dual 2 ohm (D2) and dual 4 ohm (D4), the FE 15 is easy to pair with a wide range of monoblock amplifiers whether you’re running a single 15 in a daily ported box or multiple 15s in a big trunk, SUV, or wall build.

Properly tuned, the FE Series 15" delivers deep, heavy-hitting bass with enough cone area and excursion to move real air, making it perfect for people who want their system to be felt as much as it’s heard.
