FE: Unreal Value. Real Bass.

Meet the FE Series—Sky High Car Audio’s most accessible line of subwoofers, created for enthusiasts who want quality bass on a budget. Designed for clean output, daily reliability, and efficient power handling, the FE Series proves that affordable doesn’t mean under-built. With real motor strength, high-temp voice coils, and thoughtful design elements carried over from our higher-end lines, this is entry-level done the Sky High way. 

Built with a durable stamped steel basket, the FE Series keeps costs low while maintaining solid structural integrity. The 6.5” FE starts under $100 shipped—something nearly unheard of in today’s audio market—yet still brings serious low-end performance to the table. 

The 6.5” and 8” FE models feature 2” 4-layer high-temp voice coils, rated at 300W and 400W RMS respectively. Both use double-stacked ferrite motor structures, and come equipped with Sky High 10-gauge direct leads for clean, simple connections in tight installs.

Moving up to the 10”, 12”, and 15” versions, each sub is powered by a 2.5” 4-layer high-temp coil and rated for 700W RMS. These larger models feature a double-stacked ferrite motors, but are upgraded with push terminals for secure, high-current connectivity. They’re built to offer strong musical performance while giving builders and hobbyists a sub they can rely on at an unbeatable price point.

Whether you’re building your first system, upgrading a stock setup, or stacking value in a budget-friendly build, the FE Series delivers.
