When it comes to serious subwoofers — the kind that don’t just rattle your mirrors, but turn your entire ride into a rolling sonic weapon — few names hold the weight of Fi Car Audio.
At Deviate Sound Solutions, we’re proud to bring Fi’s legendary hand-built subs directly to our customers and dealers. If you’re chasing big SPL scores, daily low-end authority, or simply want gear that’s built in the USA by people who live and breathe bass, Fi needs to be on your radar.
Fi Car Audio is all about doing things the right way, not the easy way. Every subwoofer they produce is:
✅ Handcrafted in Las Vegas — not churned out on a mass assembly line overseas.
✅ Fully customizable — from coils to cooling, to spiders and dust caps. Your build gets exactly what it needs.
✅ Engineered for extreme duty — these aren’t disposable woofers. Fi subs are made to take serious power and keep pounding.
Unlike mass-market brands, Fi doesn’t design products for “one size fits all.” Instead, they build serious equipment for serious enthusiasts and competitors — people who know exactly what kind of bass they want, and demand gear that can keep up.
Whether you’re building a ground-pounding daily driver or an all-out SPL beast, Fi’s lineup covers it all:
With customizable options like extra spiders, flatwound coils, and direct leads, Fi allows you to tailor your sub exactly to your needs — something rare in today’s “plug-and-play” audio world.
The Fi story is rooted in competitive car audio. From early days of building custom drivers for top competitors to refining designs that can survive thousands of watts without breaking a sweat, Fi has always been about pushing limits.
When you choose Fi, you’re not just buying a subwoofer. You’re investing in:
