It is suited to drivers building a complete amplified audio system without adding separate full-range and mono amplifiers. Its five-channel layout provides dedicated amplification for a four-speaker system plus bass reinforcement.\u003c\/p\u003e\u003cp\u003eAt 4 ohms, the GM-DX975 delivers 75 watts RMS to each of four full-range channels and 350 watts RMS to its subwoofer channel. The subwoofer channel can provide up to 600 watts RMS at 2 ohms, while the full-range channels can be bridged for a three-channel configuration. This flexibility supports conventional front-and-rear speaker systems as well as systems focused on amplified front components and a subwoofer.\u003c\/p\u003e\u003cp\u003eClass-D amplification helps deliver substantial output in a compact format suited to space-conscious vehicle installations. The full-range channels extend to 50 kHz and the amplifier is Hi-Res Audio Certified, making it appropriate for systems intended to preserve extended high-frequency playback. Gold-plated RCA terminals and high-grade electronic components support dependable signal connections within a properly installed system.\u003c\/p\u003e\u003cp\u003eBuilt-in crossover controls allow the system to be tailored to the speakers and subwoofer being used. The A\/B channels offer selectable high-pass or low-pass filtering from 40 Hz to 500 Hz, while the subwoofer channel includes an adjustable low-pass filter in the same range. A selectable subwoofer low-pass slope and bass boost control add further tuning options for bass integration.\u003c\/p\u003e\u003cp\u003eThe GM-DX975 can accept RCA-level signals or speaker-level signals from a compatible factory or aftermarket stereo. Its speaker-level input can automatically turn the amplifier on when it detects a head-unit speaker signal, though this function may not work with every head unit. A wired bass boost remote is included for convenient adjustment of subwoofer bass boost from the listening position.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Channel Layout:\u003c\/strong\u003e Powers four full-range speaker channels and one dedicated subwoofer channel from a single amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass-D Amplification:\u003c\/strong\u003e Provides efficient amplified power in a compact chassis for vehicle audio installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHi-Res Audio Certified:\u003c\/strong\u003e Full-range response extends to 50 kHz for compatible high-resolution audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Power Configuration:\u003c\/strong\u003e Supports five-channel operation or three-channel operation with bridged full-range channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e Adjustable high-pass and low-pass filters help match output to speakers and subwoofers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Lets the listener adjust subwoofer bass boost from an accessible mounted location.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GM-DX975 uses a compact 302 mm-wide chassis with high-grade electronic components and gold-plated RCA terminals. Its layout includes gain controls, filter controls, input-selection switches, power\/protection indication, speaker-level input, and a connection for the wired bass boost remote. The protection system monitors abnormal conditions including output shorts, DC voltage at the speaker output, and excessive internal temperature.\u003c\/p\u003e\u003cp\u003eInstall the amplifier on a rigid surface with adequate ventilation above the chassis, and do not cover it with carpet or a floor mat. It requires a 12-volt negative-ground vehicle electrical system, with separately sold battery and ground wiring sized for the installation length; speaker and subwoofer wire should be 12 to 16 AWG. Use RCA inputs with an aftermarket receiver or the supplied-style speaker-input connection method with compatible factory speaker outputs, but do not connect both input types at the same time.\u003c\/p\u003e","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":45633218117702,"sku":"GM-DX975","price":612.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61nNIJ0ctFL.jpg?v=1784418341","url":"https:\/\/audiowatt.store\/products\/pioneer-gm-dx975-5-channel-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
