Its compact mounting profile helps make bass upgrades possible in trucks, under-seat enclosures, and other limited-depth locations. It is intended for custom car-audio installations using a separate compatible amplifier.\u003c\/p\u003e\u003cp\u003eWith a 500-watt RMS power rating and 1000-watt maximum power rating, the ADS840 is built to add low-frequency output to an aftermarket system. Its 4-ohm impedance supports pairing with compatible mono or multi-channel amplifiers. The 8-inch format is a practical choice for systems that need bass reinforcement while preserving cabin or cargo space.\u003c\/p\u003e\u003cp\u003eThe shallow-mount layout uses a published mounting depth of 3.46 inches, helping installers work around space restrictions common in compact vehicles and truck interiors. A 7.28-inch cutout diameter provides the key measurement needed when planning a compatible enclosure baffle. Measure available depth behind the mounting surface, including clearance for wiring and enclosure construction, before installation.\u003c\/p\u003e\u003cp\u003eA rigid low-profile cone is specified for the ADS840, supporting a space-conscious design without relying on a full-depth driver profile. The design is intended to maintain consistent bass output in compact applications. Specific cone material, voice-coil details, and Thiele\/Small parameters are not published in the available product information.\u003c\/p\u003e\u003cp\u003eThe ADS840 can be used in either sealed or ported enclosures, allowing the enclosure design to be matched to available space and listening goals. A sealed enclosure may suit installations prioritizing a compact footprint, while a properly designed ported enclosure can be considered where enclosure volume permits. For a complete upgrade, pair the subwoofer with a compatible amplifier, enclosure, wiring, and appropriate system tuning.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8-Inch Shallow Design:\u003c\/strong\u003e Fits applications with limited mounting depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W RMS Rating:\u003c\/strong\u003e Supports amplifier matching for sustained output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1000W Maximum Power:\u003c\/strong\u003e Provides short-term peak power handling specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Works with compatible aftermarket amplifier configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.46-Inch Mounting Depth:\u003c\/strong\u003e Helps accommodate tight enclosure locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Or Ported Compatibility:\u003c\/strong\u003e Supports multiple custom enclosure approaches.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ADS840 uses a rigid, low-profile cone design intended for shallow-mount subwoofer installations. Its compact 8-inch driver format and shallow 3.46-inch mounting depth are the primary design considerations for space-limited systems. Published information does not specify the cone material, surround material, basket material, magnet details, or voice-coil construction.\u003c\/p\u003e\u003cp\u003ePlan the enclosure around the 7.28-inch cutout diameter and verify that at least 3.46 inches of mounting depth is available behind the baffle, with additional room for terminals and wiring. Use a compatible external amplifier designed for a 4-ohm subwoofer load, and select a sealed or ported enclosure according to the available installation space. Enclosure volume, port tuning, wiring method, and amplifier gain settings are not published for this model and should be determined during system design.\u003c\/p\u003e","brand":"Audio360","offers":[{"title":"Default Title","offer_id":45614102446150,"sku":"ADS840-SHALLOW","price":56.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61uFX9GYk2L.jpg?v=1784358716","url":"https:\/\/audiowatt.store\/products\/audio360-ads840-shallow-8-shallow-mount-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
