Show original supplier description
The Alpine PSU-300CRA is a 300-watt powered sound system upgrade package specifically designed for 2014-2018 Toyota Corolla 4-door models. This system delivers an enhanced audio experience by including a PWE-S8 powered subwoofer and a KTP-445U 4-channel power pack amplifier. These components come pre-assembled onto a compact under-seat installation bracket for a streamlined setup. Installation is made simple with a plug-and-play design and a vehicle-specific wiring harness. The compact nature of the system allows it to fit discreetly under the passenger seat, directing bass output to the front of the vehicle for improved impact and overall volume. Each system is also pre-tuned for the specific car model, eliminating the need for complex sound adjustments. The PSU-300CRA is compatible with the factory base radio, provided it does not have an amplified or premium factory system. It also works with Alpine head units and other aftermarket head units. It is important to note that this system is not compatible with models that feature an amplified or premium factory system.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
