It delivers 500 watts RMS into a 2-ohm load at 1% THD, making it suited to a properly matched 2-ohm subwoofer setup. Its single-channel design focuses system resources on low-frequency reproduction rather than full-range speaker amplification.\u003c\/p\u003e\u003cp\u003eThis amplifier is a practical choice for drivers upgrading a factory or aftermarket audio system with dedicated bass. RCA pre-in and speaker-level inputs provide connection options for many source units, including systems that retain the factory radio. A full-range pre-out also supports expansion to additional amplifiers.\u003c\/p\u003e\u003cp\u003eThe DP1-500 uses Advanced Class-D circuitry and is stable to 2 ohms. Its 86% efficiency helps it provide substantial subwoofer power from a compact chassis. With a 10 Hz to 500 Hz bandwidth, it is engineered for bass-channel duty.\u003c\/p\u003e\u003cp\u003eSystem tuning is handled with an adjustable low-pass filter, a selectable 25 Hz subsonic filter, phase selection, and bass boost centered at 50 Hz. These controls help blend a subwoofer with the vehicle's main speakers and accommodate different enclosure designs. Balanced pre-in and speaker-in circuitry is included to help reject noise in the signal path.\u003c\/p\u003e\u003cp\u003eFor integration with newer factory systems, the built-in Universal Speaker Simulator is designed to work with head units that monitor speaker load. Automatic Remote Turn-On\/Off can be triggered from compatible BTL speaker-level outputs, reducing the need for a separate remote-turn-on connection in applicable installations. The amplifier is also compatible with the optional Hertz HRC 02 remote level control.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W RMS at 2 Ohms:\u003c\/strong\u003e Supplies dedicated power for a properly matched subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Class-D Design:\u003c\/strong\u003e Delivers efficient bass amplification in a compact footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Connects to aftermarket radios or compatible factory systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Speaker Simulator:\u003c\/strong\u003e Supports integration with speaker-load-detecting factory head units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Tuning Controls:\u003c\/strong\u003e Low-pass, subsonic, phase, and bass boost aid system setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Range Pre-Out:\u003c\/strong\u003e Makes it easier to add another amplifier later.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe DP1-500 combines a compact 190 x 152 x 50 mm chassis with a removable top panel that protects its controls and connections. It uses solid machined terminal blocks and an integrated status LED. The amplifier weighs 1.62 kg and is intended for installation inside the vehicle, away from water, excess humidity, dust, and dirt.\u003c\/p\u003e\u003cp\u003eUse this amplifier with a subwoofer system presenting no less than a 2-ohm final load. It requires a 12V negative-ground vehicle electrical system, a fused power connection, ground wiring, and either RCA pre-in or speaker-level input wiring. Allow ventilation around the amplifier, set the input level and filters during installation, and use the optional HRC 02 only if in-cabin subwoofer-level adjustment is desired.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631728484422,"sku":"DP1-500","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61pOs9m8hYL_0bfbc438-0339-4f16-a3b8-d89c6d9194e7.jpg?v=1784380243","url":"https:\/\/audiowatt.store\/products\/hertz-dp1-500-mono-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
