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.\u003c\/p\u003e\u003cp\u003eRated 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.\u003c\/p\u003e\u003cp\u003eAn 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eAt 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.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Powered Woofer:\u003c\/strong\u003e Combines a 10-inch 4-ohm woofer and built-in amplifier in one enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1500W Peak Rating:\u003c\/strong\u003e Provides a published maximum peak-power rating for added bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Low-Pass Filter:\u003c\/strong\u003e Offers 50Hz to 150Hz tuning for blending with full-range speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Bass Boost:\u003c\/strong\u003e Adjusts bass emphasis from 0 to +24dB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Input Compatibility:\u003c\/strong\u003e Supports high-level and low-level source connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow Enclosure:\u003c\/strong\u003e Measures 68mm deep for space-conscious vehicle installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eMount 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.\u003c\/p\u003e","brand":"Audio360","offers":[{"title":"Default Title","offer_id":45613491093574,"sku":"AD1500US","price":183.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71W8-sfWDzL.jpg?v=1784350681","url":"https:\/\/audiowatt.store\/products\/audio360-ad1500us-10-powered-under-seat-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
