Alpine PSS-TSUB-T3A 10" Custom-Fit Subwoofer with Sealed Enclosure and Mono Amp for Select 2017-23 Tesla Model 3 with Factory Premium Audio

Alpine PSS-TSUB-T3A is a 10” custom-fit subwoofer upgrade built for select 2017–2023 Tesla Model 3 vehicles with factory premium audio, and it immediately steps up your bass experience with deeper, tighter, and more controlled low-end output.

A Clear Step Up From Factory Bass

If you’ve ever felt like your Tesla’s stock bass is a little too polite, this is where things get interesting. This upgrade swaps out the factory 8” subwoofer for a larger 10” sealed design, giving your low frequencies more room to breathe and hit harder. The result is a sound that feels fuller and more grounded, especially when the music demands real depth.

Instead of just hearing bass, you start to feel it in a way that stays clean and controlled, even at higher levels.

Designed to Fit Without Changing the Look

One of the biggest advantages here is how naturally everything fits into the vehicle. The system is designed specifically for the factory subwoofer location in compatible Model 3 vehicles, so the interior layout stays untouched.

That means no awkward changes to your cargo space or factory design. It keeps the clean Tesla aesthetic intact while quietly upgrading what’s happening underneath the surface.

Plug-and-Play Simplicity With Smart Integration

Everything in this system is built around compatibility with Tesla’s factory premium audio setup. It includes Tesla-specific harnesses, a pre-tuned enclosure, and an integrated mono amplifier setup featuring the Alpine KTA-200M.

Because of this, Alpine PSS-TSUB-T3A works in harmony with the existing system instead of fighting against it. OEM functionality stays fully intact, so you’re not trading features for performance—you’re just adding more capability.

More Power When the Music Demands It

At the heart of the system, the included Alpine KTA-200M mono amplifier uses efficient power delivery with Dynamic Peak Power technology. That means it can respond quickly when the music spikes, giving you stronger bass impact right when you need it most.

At the same time, it avoids unnecessary constant power draw, keeping performance efficient and balanced during everyday listening. It’s a smart approach to power that fits the nature of an electric vehicle.

Bigger, Deeper, Cleaner Low-End

Where this upgrade really stands out is in how it reshapes the low-frequency range. With a 10” sealed subwoofer, hybrid carbon fiber cone, and H.A.M.R. surround technology, the bass feels more controlled and more precise.

Instead of loose or muddy low-end, you get defined bass notes that stay tight even when the volume climbs. That balance is what makes long drives more enjoyable—you can turn it up without losing clarity.

Alpine PSS-TSUB-T3A doesn’t just add bass; it refines it so it feels like it belongs there from the start.

Built for a Seamless Listening Experience

Everything about this setup is focused on keeping things smooth and natural. From frequency response tuned for Tesla acoustics to maintaining full OEM functionality, the system blends into the vehicle’s sound profile instead of overpowering it.

The result is a more immersive driving experience where music feels wider, deeper, and more engaging without disrupting the original system behavior.

A More Engaging Drive Every Time

Once installed, Alpine PSS-TSUB-T3A changes how everyday listening feels. Bass-heavy tracks gain impact, but even lighter music benefits from the added depth and presence.

It’s the kind of upgrade you notice immediately—not because it’s overwhelming, but because it finally feels like something was missing before.
