It is intended for drivers building an entry-level to mid-level bass upgrade who need a separate amplifier rather than relying on head-unit power. With a 2-ohm stable mono configuration, it provides a practical foundation for a single subwoofer or a properly wired multi-subwoofer setup.\u003c\/p\u003e\u003cp\u003eThis amplifier delivers 300 watts RMS through one channel at 2 ohms and 200 watts RMS at 4 ohms. Its low-frequency operating range supports subwoofer duty, while the adjustable low-pass and subsonic filters help tailor output to the enclosure and speaker system. The result is controlled bass integration rather than sending unwanted midrange content to the subwoofer.\u003c\/p\u003e\u003cp\u003eThe SRX300.1V includes both low-level RCA and speaker-level signal inputs. This makes it suitable for systems with aftermarket radios as well as many factory-source installations that do not provide preamp outputs. A wired remote level control is included for convenient adjustment from the driver's seat.\u003c\/p\u003e\u003cp\u003eIts Street Reference design uses a textured aluminum heatsink to support heat dissipation in a compact chassis. An ultra-bright LED accent strip adds visible styling to an amplifier installation, while onboard power and protection indication helps communicate operating status. The control layout keeps gain, crossover, bass boost, and subsonic adjustments accessible during setup.\u003c\/p\u003e\u003cp\u003eThe amplifier is a sensible match for subwoofers whose continuous power requirements align with its rated output at the final wired impedance. It is not a full-range multi-channel amplifier, so it is best used as the dedicated bass section of a system with separate amplification or head-unit power for the main speakers. An 8-gauge amplifier wiring kit is recommended for installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300W RMS Mono Output:\u003c\/strong\u003e Supplies dedicated subwoofer power at a 2-ohm load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stability:\u003c\/strong\u003e Supports correctly wired 2-ohm or 4-ohm subwoofer loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Helps keep higher frequencies out of the subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Subsonic Filter:\u003c\/strong\u003e Reduces excessively low frequencies below the selected setting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Bass Boost:\u003c\/strong\u003e Provides adjustable low-frequency emphasis at 45 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Remote Level Control:\u003c\/strong\u003e Lets the driver adjust bass level conveniently.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SRX300.1V uses a black textured aluminum heatsink chassis with an integrated LED accent light strip. Its compact footprint measures approximately 10.1 by 7.87 by 2.16 inches, allowing it to fit in many trunk, hatch, and under-seat-style amplifier locations when ventilation and clearance are provided. The aluminum enclosure is designed to help dissipate heat during operation.\u003c\/p\u003e\u003cp\u003eUse an 8-gauge amplifier wiring kit, a properly fused battery power connection, and a solid chassis ground for installation. Connect the amplifier through RCA inputs when the source unit provides preamp outputs, or use the supplied speaker-level input harness for compatible factory-radio systems. Set gain and crossover controls during installation, and wire the connected subwoofer system so the final load is no lower than 2 ohms.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633204060230,"sku":"SRX300-1V","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61byWOIHo-L.jpg?v=1784415897","url":"https:\/\/audiowatt.store\/products\/memphis-srx300-1v-300w-mono-subwoofer-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
