Description
The Seventour 10-inch under-seat subwoofer is a compact powered car audio solution designed for drivers who want stronger low-end response without sacrificing cabin or cargo space. Built to fit beneath a seat in many cars and trucks, the enclosure measures 13.5 inches long, 10.2 inches wide, and 3.1 inches thick, so it can be a practical option where a traditional subwoofer box would be difficult to place. Before installation, it is still important to confirm available space, mounting clearance, and vehicle-specific requirements.
At the center of the system is a 10-inch driver paired with a built-in amplifier, delivering 220 watts RMS and up to 800 watts peak power. This active design simplifies integration while helping produce deeper bass support for factory or aftermarket audio systems. The cast-aluminum enclosure is not only sturdy, but also helps manage heat during operation, which can support consistent performance over time.
For sound tuning, the subwoofer offers a frequency response of 20Hz to 500Hz, a low-pass filter adjustable from 50Hz to 150Hz, and bass boost control from 0 to 12dB at 45Hz. These settings make it easier to match the subwoofer to the vehicle interior and listening preferences, whether the goal is subtle reinforcement or a more noticeable bass presence. With a signal-to-noise ratio above 90dB and total harmonic distortion below 0.4%, the unit is designed to deliver clean, controlled output.
Installation flexibility is another key feature. The Seventour under-seat subwoofer supports both low-level RCA inputs and high-level speaker inputs, along with adjustable input sensitivity. This makes it easier to connect to a wider range of audio systems. A wired remote control allows bass volume to be adjusted from the driver’s seat, which can be helpful when switching between music styles or driving conditions.
Built-in protection circuitry adds another layer of reliability, with thermal, short-circuit, and overload safeguards included. A green power indicator and red protection light provide quick status feedback during use. The unit also includes a personalized speaker protector and a blue LED ambient light ring that illuminates when the vehicle starts, adding a visible accent to its functional design.
With a rated 25A fuse and support designed for practical everyday use, this active under-seat subwoofer offers a compact way to improve bass performance while preserving space. For best results, reviewing power, grounding, and input compatibility before installation can help ensure the system works smoothly with the existing vehicle audio setup.
