Audio360 AD1500US 10" Powered Under-Seat Subwoofer

The AUDIO360 AD1500US is a compact powered subwoofer system designed to add low-frequency output to vehicle audio systems without requiring a separate subwoofer enclosure and external amplifier. Its integrated 10-inch, 4-ohm woofer and built-in amplifier are housed in a shallow enclosure intended for under-seat or limited-space installations. It is a practical option for drivers who want more bass while preserving usable cargo and cabin space.

Rated for up to 1500 watts of peak power, the AD1500US is intended to provide added bass impact for factory and aftermarket sound systems. Its published frequency response is 55Hz to 20kHz, with a signal-to-noise ratio above 90dB and total harmonic distortion below 0.4%. These specifications support a clean, controlled addition of low-end reinforcement when the system is set up correctly.

An adjustable low-pass filter from 50Hz to 150Hz lets the subwoofer be matched to the frequency range handled by the vehicle's main speakers. This allows the installer to set the handoff point according to the speakers, source unit, and listening preference. A 20Hz subsonic filter is also specified to limit very low frequencies outside the intended operating range.

The AD1500US includes variable bass boost adjustment from 0 to +24dB for tailoring bass emphasis. High-level and low-level input options support integration with either factory speaker-output signals or aftermarket receiver preamp signals. Published input sensitivity is 0.9V for high-level input and 300mV for low-level input.

At 345 x 262 x 68mm, the enclosure is built for installations where conventional subwoofer boxes are impractical. The slim 68mm profile can suit many under-seat and shallow cargo-area locations, subject to vehicle clearance and safe mounting access. Integrated circuit protection and a 25A fuse are specified to help protect the powered subwoofer during operation.

• Adjustable Low-Pass Filter: Offers 50Hz to 150Hz tuning for blending with full-range speakers.
• Variable Bass Boost: Adjusts bass emphasis from 0 to +24dB.
• Dual Input Compatibility: Supports high-level and low-level source connections.
• Shallow Enclosure: Measures 68mm deep for space-conscious vehicle installations.

Design & Installation

The AD1500US uses an all-in-one powered-subwoofer enclosure design, combining the woofer and amplifier in a compact 345 x 262 x 68mm housing. The published information confirms integrated circuit protection and a 25A fuse, but does not identify the enclosure, cone, or surround materials. Its shallow form factor is designed for applications with restricted mounting depth.

Mount the enclosure securely in a location with adequate clearance, ventilation, and protection from cargo or passenger contact. Use the supplied power and signal wiring harness as applicable, choose high-level input for speaker-output signals or low-level input for receiver preamp signals, and set the low-pass filter and bass boost conservatively before final tuning. Confirm under-seat clearance, wiring routes, and vehicle electrical requirements before installation.
