The PSS-TSLA-T3A is a 10" sealed, preloaded Subwoofer and power pack amplifier kit designed for plug and play performance for the 2017 - 2023 tesla model 3 through factory equipped premium sound system.
The PSS-TSLA-T3A directly replaces the factory tesla 160 W 8" Subwoofer in the rear trunk panel through a powerful, 200 W 10" sealed Subwoofer without cutting or modification. Paired through the ultra efficient KTA-200M, this system delivers a dramatic increase in output and low end clarity, giving your tesla a noticeably more powerful and immersive audio experience. Using Alpine's proprietary amplifier technology, dynamic peak power (DPP), the KTA-200M intelligently doubles power during dynamic musical passages for ultimate efficiency through less than a mile range used at full volume. The lightweight yet durable hybrid carbon fiber cone material reproduces precision bass without adding additional weight to your tesla. Expertly crafted for the tesla model 3, the PSS-TSUB-T3A comes alongside everything you need for plug and play installation, including a preloaded and tuned Subwoofer enclosure, line output converter, tesla specific harnesses, and power wiring. Designed for seamless integration, the Subwoofer is factory matched in performance through full OEM function retention.
