Its Constant Power configuration delivers rated output across 1-, 2-, and 4-ohm loads, helping simplify subwoofer selection and wiring options. It is suited to vehicle audio upgrades that need a dedicated low-frequency amplifier rather than a full-range multi-channel design.\u003c\/p\u003e\u003cp\u003eRated at 500 watts RMS into 1 or 2 ohms and 300 watts RMS into 4 ohms, the T500-1BDCP is intended for properly matched subwoofers and enclosures. The mono layout focuses its output on bass reproduction from 20 Hz to 250 Hz. A variable low-pass crossover helps blend the subwoofer with the rest of the system.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a Class BD circuit topology with MOSFET power-supply and output stages. Its adjustable Punch EQ provides a targeted bass boost at 45 Hz, while the selectable infrasonic filter limits very low frequencies sent to the woofer. These controls give installers practical options for tailoring output to the vehicle, enclosure, and music preference.\u003c\/p\u003e\u003cp\u003eRCA inputs support connection from a compatible source unit or signal processor, and RCA pass-through outputs can feed an additional amplifier without an extra long signal run. Balanced inputs are included to support noise-resistant signal integration. Power, thermal, and protect indicators provide at-a-glance operating status.\u003c\/p\u003e\u003cp\u003eThe T500-1BDCP fits naturally into a subwoofer-focused upgrade path for systems that need more low-frequency authority without adding extra amplified channels. It accepts 4 AWG power and ground wiring and uses heavy-duty speaker terminals for secure connections. Proper impedance matching, fused power wiring, grounding, and gain setup are important for dependable operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstant Power Design:\u003c\/strong\u003e Provides rated output at 1-, 2-, and 4-ohm mono loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass BD Topology:\u003c\/strong\u003e Dedicated mono amplification for a subwoofer-focused system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Crossover:\u003c\/strong\u003e Adjusts from 35 Hz to 250 Hz for system blending.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePunch EQ:\u003c\/strong\u003e Adds adjustable bass boost from 0 to +18 dB at 45 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInfrasonic Filter:\u003c\/strong\u003e Selectable 28 Hz filter helps manage ultra-low frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA Pass-Through:\u003c\/strong\u003e Allows convenient signal daisy-chaining to another amplifier.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe amplifier uses a cast-aluminum heatsink to dissipate heat generated by its circuitry. Nickel-plated power, ground, speaker, RCA, and remote connections are designed to resist corrosion and provide solid wiring contact.

Use 4 AWG power and ground cable, keep the ground connection short, and install the required external fuse within 18 inches of the battery. Connect a compatible RCA signal source, match the connected subwoofer load to the amplifier's supported 1- to 4-ohm operating range, and set gain and crossover controls carefully.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45658575437894,"sku":"T500-1BDCP","price":549.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71tCMyGyvwL.jpg?v=1784445398","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-t500-1bdcp-500w-mono-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
