Add Bass Without a Large Separate Enclosure

An 8-inch under-seat subwoofer brings a speaker and built-in amplifier together in a slim enclosure for a compatible car audio setup. With a listed 3-inch height, high- and low-level inputs and adjustable controls, this active bass box gives you a compact option to evaluate against the available space in your vehicle.

Key Benefits

• Built-in amplifier: Combines amplification and the subwoofer in one unit; power and signal wiring are still required.
• Slim enclosure: Listed product dimensions are 12.4 × 9.44 × 3 inches.
• Adjustable controls: The listing describes phase shift, bass boost and input gain adjustment.
• Input options: High- and low-level inputs for matching a compatible audio system.
• Installation accessories: Includes connecting wires, an English manual, brackets and screws.

Build your next audio upgrade around the space and equipment you actually have. Have an installer check clearances, input connections and power requirements, then tune the bass to complement your existing speakers rather than relying on maximum output alone.

Fit, Wiring and What Is Included

The package lists one subwoofer, five matched connecting wires, one English manual and one set of installation brackets and screws. The 200W figure is specified as peak power, not continuous RMS output. Professional installation is recommended. Confirm electrical compatibility before purchasing and follow the manual for power, signal connections and adjustment.

Allow clearance for seat movement and adequate ventilation. Secure the enclosure and wiring away from moving components and safety equipment. Keep volume at a level that allows awareness of surrounding traffic, and adjust controls only while parked.
