It provides one amplified output channel and supports subwoofer-focused tuning controls. This makes it a practical choice for adding dedicated low-frequency amplification to a vehicle audio system.\u003c\/p\u003e\u003cp\u003eIts rated output is listed at 1 x 1,250 watts at 4 ohms and 1 x 2,500 watts at 2 ohms. The mono configuration is intended for a single subwoofer or a properly wired group of subwoofers. Matching the final speaker load to the amplifier's supported power ratings is important during system planning.\u003c\/p\u003e\u003cp\u003eThe GP-2500.1 uses a Class A\/B amplifier design with Crunch SPEED-FET MOSFET output devices and a pulse-width-modulated power supply. A low-noise preamplifier circuit is used at the signal input stage. Together, these features support a subwoofer amplifier layout with adjustable bass-system controls.\u003c\/p\u003e\u003cp\u003eFor tuning, the amplifier includes a variable electronic 12 dB-per-octave crossover, a 10-40 Hz subsonic filter, phase adjustment, and selectable bass boost. These controls help integrate the subwoofer with the rest of the system and tailor its operating range. A wired bass remote is included for accessible adjustment from the vehicle cabin.\u003c\/p\u003e\u003cp\u003eThe amplifier accepts low-level RCA signals as well as high-level speaker inputs for systems without RCA outputs. This allows it to work with many aftermarket and factory-style source units when installed with the appropriate wiring. Its RCA output can also pass signal onward to a second amplifier.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Subwoofer Output:\u003c\/strong\u003e Single-channel design for dedicated subwoofer amplification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Power Rating:\u003c\/strong\u003e Delivers 1 x 2,500 watts at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossover:\u003c\/strong\u003e 12 dB-per-octave electronic filtering supports system tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Adjustable 10-40 Hz filter helps manage very low frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Inputs:\u003c\/strong\u003e Connects to source units without RCA outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Provides convenient in-vehicle bass-level adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GP-2500.1 has a black and red chassis with a QTD aluminum heat sink for thermal dispersion. Nickel-plated brass terminals are paired with screw-down connectors for the power, ground, and speaker connections. LED diagnostic indicators provide visual monitoring for overload and speaker-short protection.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely on a surface with adequate ventilation, and do not mount it upside down. The manufacturer specifies 4 AWG power and ground terminals, 12 AWG speaker terminals, and two 30A fuses. Use RCA inputs where available, or use the supplied high-level-input harness with a source unit that lacks RCA outputs.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45624228544582,"sku":"GP-2500-1","price":147.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61RDzQwyfEL.jpg?v=1784373215","url":"https:\/\/audiowatt.store\/products\/crunch-gp-2500-1-2500w-monoblock-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
