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.

What Others Are Saying
Eddie was great - SDCS installed a new head unit in my 2019 4Runner. He was honest in his opinions regarding the options I was considering. Pricing was also good - he was able to reuse some of my existing installation kit so I saved a bit of $$.Installation was clean and fast and he took the time to walk through the features before I left. Highly recommend!!
I had a great time at this shop! The staff really knows their stuff and took the time to explain the different options without pressure. Installation was quick, clean and professional. Everything looks factory and sounds amazing. The prices were fair and customer service was above and beyond. I highly recommend this place if you're looking for quality car audio and excellent service.
Those guys are really professional! I had a new Alpine floating head unit installed in my 2008 Mercedes, and it feels like a brand-new car. The installation was super clean. At first, the sound wasn’t the same as the factory stereo, but Kevin tuned it to be just as good—if not better—without adding any new amps. They even used my factory GPS antenna so I don’t have extra wires hanging out. On top of that, they matched the online price. Big thanks to Kevin and Eddie—highly recommended!
Kevin was awesome, he took his time and explained everything to me. I went in initially for a dash cam install and then decided to get a sub and amp installed as well. Both turned out great and will be returning if I need more work done.
Came In not knowing what to expect when suddenly my stereo stopped working. Spoke with Kevin in the front and after a VERY fast diagnosing they discovered my wiring was incorrect. After only about 45 minutes total being in the store I was on my way to the beach with a working stereo again! Thank you so much SDCARSTEREO
Highly recommend Kevin and the team at San Diego Car Stereo for any issues with aftermarket stereos. I bought a car with an aftermarket stereo and AC unit that wasn’t working properly—specifically, the heat wasn’t functioning due to an improper setup. I had several people look at it with no luck, and even the dealership basically refused to help because it was an aftermarket install. I came to Kevin and his team over the holidays feeling pretty defeated, but he was confident he could get the heat working before I headed back to a Colorado winter. Sure enough, he got it done.
