Audiotek AT-800US 10" Slim Powered Under-Seat Subwoofer

The Audiotek AT-800US is a 10-inch powered subwoofer enclosure designed to add low-frequency output to a car or truck audio system without requiring a separate external amplifier. Its slim, angled enclosure is intended for space-conscious installations, including under-seat, trunk, or behind-seat locations where clearance permits. The integrated amplifier and enclosure simplify a bass upgrade compared with assembling separate subwoofer, box, and amplifier components.

This model is suited to drivers who want more bass presence from factory or aftermarket speakers while retaining usable cabin and cargo space. It accepts both RCA low-level and speaker-level signals, allowing it to work with many head units and factory-radio integration setups. Check available clearance and plan the power, ground, and turn-on connections before installation.

Confirmed published specifications list 200 watts RMS and 400 watts peak output for the AT-800US. Its bass adjustments include variable gain, a built-in low-pass filter, selectable phase, and a variable bass boost control. These controls help match bass level and blend the subwoofer with the vehicle's main speakers.

The AT-800US uses an aluminum chassis intended to help dissipate heat during operation, while a front metal grille helps protect the subwoofer driver. Power and protection LED indicators provide basic operating-status feedback. Overheat and reverse-polarity protection are also listed for the integrated powered enclosure.

As an active subwoofer, the AT-800US is a self-contained addition to a vehicle audio system rather than a passive subwoofer requiring an outboard amplifier. A wired remote level control is included for convenient bass adjustment from the cabin. It can be used as a compact bass foundation in an OEM-radio upgrade or paired with an aftermarket receiver that has RCA preamp outputs.

Design & Installation

The AT-800US is built around a slim aluminum chassis with an angled enclosure profile. Its aluminum construction is listed to assist heat dissipation, and the front metal grille helps shield the driver from incidental contact. Power and protection indicators provide visible operating feedback.

Mount the enclosure securely in a ventilated location with sufficient clearance, such as under a seat, in a trunk, or behind a rear seat. Connect fused battery power, a short chassis ground, remote turn-on, and either RCA low-level or speaker-level signal wiring as appropriate for the vehicle. Set gain, low-pass filter, bass boost, and phase gradually after installation to blend the subwoofer with the rest of the system.
