Top-mounted controls keep crossover, EQ, and level adjustments accessible after installation. Its chassis measures 1.6 inches high by 4.3 inches wide by 8.3 inches deep.\u003c\/p\u003e\u003cp\u003eUse an 8 AWG power and ground connection, with a 60A fuse installed in the power wiring as specified. The amplifier accepts front and rear high- or low-level signals through its included input harnesses, and its two 4-pin speaker harnesses connect the front and rear speaker outputs. For a two-channel source, select 2-channel input mode; use 4-channel mode when separate front and rear signals are available.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45658872086598,"sku":"TM400X4AD","price":629.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71zC2lWOlIL.jpg?v=1784445545"}],"url":"https:\/\/audiowatt.store\/collections\/marine-amplifiers.oembed?page=2","provider":"Audio Watt Store","version":"1.0","type":"link"}
