Stage 2 Under-Seat Subwoofer Enclosure Loaded With (2) Wāvtech Thin Pro 12"s
This is the cleanest way to add real bass to your Ford without ruining the interior. Our Stage 2 sealed under-seat enclosure is built for OEM-plus fitment and comes loaded with (2) Wāvtech Thin Pro 12" subs — already mounted, pre-wired, and ready to drop in.
Stage 2 is our most popular option because it looks super clean in the daytime, then the acrylic + addressable lighting makes it pop at night — without needing big viewing windows.
Fitment
Built Specifically for Ford F-Series
- Fits 2009–2026 F-150 and 2017–2026 Super Duty (F-250 / F-350) crew cab trucks.
- 3D-modeled around factory floor + seat geometry for a tight OEM-plus install.
- No seat lift required — rear seat functionality stays completely factory.
- Designed to look intentional under the seat — not like a generic prefab box shoved in there.

Performance
How It Sounds
This setup is built for daily driving — clean bass, tight response, and way more output than a small prefab setup. It’ll sound good at low volume, and it’ll get aggressive when you turn it up.
For best results we recommend a quality mono amp like the Wāvtech link1500.1 (or comparable) to power it properly. If you want us to help match an amp and wiring, just message us and we’ll point you to the right setup.
And the best part: no seat lift required — you get a real system without changing how the truck functions.
