What Truck Owners Are Saying

Real feedback from the road.

Early tester reviews. Real orders are coming — we'll replace these with verified customer feedback.

The problem

Universal boxes don't fit trucks.

Generic enclosures rattle around, eat your rear legroom, and sound terrible because they're not tuned for your cab. You end up choosing between bass and actually using your back seat.

The SubCab way

Precision-fit for your exact truck.

Every SubCab enclosure is designed for a specific year, make, model, and cab configuration. It slides under your rear seat like it came from the factory. You keep your space. You get the bass.

Engineered for the seat gap.

Every detail matters when you're working in inches.

■

Vehicle-Specific Design

Modeled to the exact dimensions under your truck's rear seat. No guessing, no returns, no wasted space.

♫

Tuned Acoustics

Each enclosure is tuned for the specific air volume and sub pairing. You get clean, punchy bass, not muddy rumble.

◆

Guaranteed Fit

Every enclosure is measured to your specific year, make, model, and cab. If it's in our configurator, it fits. Period.

⚙

3/4" MDF Construction

Built from 3/4" MDF — the same material used by professional enclosure builders. Dense, rigid panels that minimize resonance and hold dimensions tighter than cheap alternatives.

Built by Hand in Tucson, Arizona — Shipped Direct to Your Door

Designed and built by hand — every one.

I started building these because I'm passionate about seeing things done fast, done correctly, and with the highest quality craftsmanship — but at a price everyone can afford. That's what drives SubCab.

Every box I build gets my full attention. No shortcuts, no outsourcing, no cutting corners on materials. If your truck is on the list, your enclosure was designed specifically for that cab — measured, built, and finished by hand right here in my shop.
