Gravity Warzone WZ100ST 10" Powered Under-Seat Subwoofer

The Gravity Warzone WZ100ST is a compact 10-inch powered subwoofer designed for vehicle installations where a conventional subwoofer enclosure would take up too much space. Its slim, under-seat-oriented form factor adds low-frequency reinforcement while preserving usable cabin or cargo room. The integrated amplifier combines the subwoofer and amplification in one enclosure, simplifying the system layout.

This model is suited to drivers upgrading a factory or aftermarket stereo that needs more bass presence without a large trunk-mounted enclosure. It supports both low-level and high-level input connections, allowing it to work with head units that do or do not have RCA outputs. Automatic turn-on capability is provided for high-level connection setups.

The WZ100ST is specified with up to 1000 watts of maximum power and a 4-ohm 10-inch subwoofer. Its listed signal-to-noise ratio is 90 dB, and the enclosure uses a passive radiator as part of its compact bass design. A variable low-pass filter helps limit the unit's output to the lower frequencies intended for subwoofer use.

Sound adjustment controls include variable bass boost, phase adjustment, and a fixed subsonic filter. The bass boost range is listed at 0 to 12 dB, while the subsonic filter is fixed at 20 Hz. A wired remote bass-level control gives the driver a convenient way to adjust bass output from the seating area.

An aluminum enclosure gives the WZ100ST a durable, low-profile housing for vehicle use. At 13.6 inches long, 10.3 inches wide, and 3.2 inches high, it is intended for tight spaces such as beneath a seat when vehicle clearance permits. It can serve as a self-contained bass upgrade alongside factory speakers, component speakers, or a full aftermarket audio system.

Design & Installation

The WZ100ST uses a slim aluminum enclosure with a vented, passive-radiator design. Its 3.2-inch height is intended to make placement possible in restricted vehicle locations while the metal housing supports a durable installation. The enclosure contains the active subwoofer system, so a separate external subwoofer amplifier is not required.

Before installation, measure the selected location against the unit's 13.6 x 10.3 x 3.2-inch dimensions and verify that seat movement, wiring, ventilation, and vehicle safety components will not be obstructed. The unit accepts low-level and high-level signal connections; use the appropriate input method for the existing head unit and set the low-pass filter, bass boost, phase control, and remote bass level to blend with the vehicle's main speakers. Professional installation is recommended when routing fused power wiring or working around seats with integrated safety systems.
