Its slim under-seat form factor is suited to vehicles with limited cabin or cargo space. The integrated amplifier keeps the installation focused on one enclosure rather than separate subwoofer and amplifier components.\u003c\/p\u003e\u003cp\u003eThis model uses an 8-inch, 4-ohm subwoofer in a self-contained enclosure and carries a 600-watt maximum-power listing. It is intended for car-audio systems that need more bass presence than factory speakers typically provide. The compact format makes it a practical option for cars, trucks, RVs, and similar vehicle applications when clearance is available.\u003c\/p\u003e\u003cp\u003eSignal connection flexibility helps the RW-108A work with a range of source units. It provides RCA low-level inputs for aftermarket receivers with preamp outputs, along with a high-level input for systems using speaker-level signal. A remote turn-on terminal and selectable auto-turn-on function support different installation approaches.\u003c\/p\u003e\u003cp\u003eOnboard adjustment controls let the installer tailor the enclosure to the rest of the system. Input-level, bass-boost, and low-pass-filter controls help blend the subwoofer with full-range speakers, while the 0\/180-degree phase switch can assist with bass integration. Power and protect indicators provide at-a-glance operating-status feedback.\u003c\/p\u003e\u003cp\u003eA wired bass-level remote is included for convenient adjustment from the cabin. This makes it easier to reduce output for everyday listening or raise it when program material calls for more low-end reinforcement. The RW-108A is best used as a compact bass upgrade in a properly fused 12-volt vehicle-audio installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8-Inch Powered Subwoofer:\u003c\/strong\u003e Combines a compact woofer and built-in amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlim Under-Seat Format:\u003c\/strong\u003e Helps conserve usable vehicle cabin and cargo space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600-Watt Maximum Rating:\u003c\/strong\u003e Provides the product's advertised maximum power specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Low-Level Inputs:\u003c\/strong\u003e Supports speaker-level wiring or RCA preamp connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass-Level Remote:\u003c\/strong\u003e Lets you adjust subwoofer output from the cabin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Integration Controls:\u003c\/strong\u003e Includes gain, bass boost, low-pass, and phase settings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe RW-108A uses a low-profile black enclosure with an integrated amplifier section and a protective grille over the woofer. Its compact layout places power, signal, remote-control, and adjustment connections together on the enclosure. Power and protect LEDs, an integrated fuse, and accessible tuning controls support routine setup and troubleshooting.\u003c\/p\u003e\u003cp\u003eMount the enclosure securely on a flat surface with adequate ventilation and without obstructing vehicle controls, seat movement, or safety equipment. Connect it to fused 12-volt power, a solid chassis ground, and either RCA or speaker-level signal; use the REM terminal or the auto-turn-on setting as appropriate for the source unit. Set gain conservatively, then use the low-pass filter and phase control to blend bass with the vehicle's main speakers.\u003c\/p\u003e","brand":"MB Quart","offers":[{"title":"Default Title","offer_id":45633164640326,"sku":"RW-108A","price":253.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81WFSzZqDzL.jpg?v=1784407659","url":"https:\/\/audiowatt.store\/products\/mb-quart-rw-108a-8-powered-under-seat-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
