Alpine PSS-TSUB-TYA Tesla Model Y Subwoofer & Amp Upgrade Kit
Product overview:
The Alpine PSS-TSUB-TYA is a high-performance, plug-and-play 10-inch subwoofer and amplifier system designed specifically for the 2020–2025 Tesla Model Y. This kit replaces the factory 8-inch subwoofer with a significantly more powerful 10-inch Alpine driver, driven by a dedicated 200W RMS mono amplifier. It is engineered to provide "ludicrous" bass performance while maintaining the vehicle's efficient power consumption and clean interior aesthetic.
Features
Seamless Connectivity
The PSS-TSUB-TYA is a true plug-and-play solution that integrates directly with the Model Y's factory system. It includes Tesla-specific wiring harnesses and a line output converter (LOC), ensuring a straightforward installation with no cutting or vehicle modifications required. This preserved connectivity ensures that all original OEM functions remain fully operational while adding professional-grade audio power.
Safety & Convenience
Designed for the energy-conscious EV driver, the included Alpine KTA-200M amplifier features Dynamic Peak Power (DPP) technology. This allows the system to deliver up to 500W of peak power during musical swells while consuming less than one mile of range even at high volumes. The stealth design preserves your cargo space by fitting the custom-shaped enclosure entirely behind the rear trunk panel, keeping the trunk floor flat and usable.
Enhanced Audio & Ambiance
This kit transforms the audio ambiance of your Tesla by introducing a lightweight hybrid carbon fiber cone subwoofer. Carbon fiber provides the stiffness needed for tight, punchy bass without adding excessive weight. Combined with Alpine's patented H.A.M.R. (High Amplitude Multi-Roll) surround, the 10-inch driver achieves deep excursion, moving significantly more air than the factory unit for a more immersive and physical listening experience.
Fine Tune Your Sound
The system arrives pre-tuned for Tesla Model Y acoustics, ensuring optimal performance right out of the box. The sealed enclosure design is optimized for accuracy and clarity across the 25Hz to 300Hz frequency range. For those looking to "fine-tune" the installation further, the custom-molded fit minimizes potential panel rattles, though Alpine recommends adding sound damping (sold separately) to the trunk cavity for the ultimate high-fidelity result.
