It provides one amplified channel for a dedicated bass speaker, helping add low-frequency output to an aftermarket audio system. Its 2-ohm-stable design supports common single-subwoofer and multi-subwoofer wiring configurations that present a safe final load.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building a subwoofer-focused system who want adjustable bass tuning rather than a full-range multi-channel amplifier. It offers up to 1 x 1,325 watts at 2 ohms and 1 x 650 watts at 4 ohms, as listed by the manufacturer. Because it is mono only, it is designed for subwoofer duty rather than powering separate left and right speakers.\u003c\/p\u003e\u003cp\u003eThe DR-1325.1 uses a Class A\/B circuit with proprietary Crunch SPEED-FET MOSFET output components. A low-noise preamplifier circuit, variable input sensitivity, and adjustable low-pass filtering help integrate the amplifier with an aftermarket or factory-compatible audio source. The onboard bass control, bass boost, and subsonic filter provide useful adjustment points when tuning a subwoofer enclosure.\u003c\/p\u003e\u003cp\u003eQuick Thermal Dispersion technology uses an aluminum heat sink to manage operating heat during normal music playback. The amplifier also uses a pulse-width-modulated power supply and nickel-plated brass terminals for its power and speaker connections. LED protection diagnostics are included to indicate overload or speaker-short protection conditions.\u003c\/p\u003e\u003cp\u003eFor everyday use, the included wired bass remote places bass-level adjustment within reach of the driver. The built-in LED VU meter can assist with gain adjustment, while the selectable logo lighting can be set to constant red, VU meter operation, or off. It is a practical choice for adding a dedicated powered subwoofer stage to a vehicle audio upgrade.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Subwoofer Channel:\u003c\/strong\u003e Delivers one dedicated channel for a bass speaker system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Output:\u003c\/strong\u003e Supports a final speaker load down to 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Tunes the upper bass cutoff from 40 Hz to 300 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Adjusts low-frequency filtering from 10 Hz to 40 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Allows convenient bass-level adjustment from the cabin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Logo Lighting:\u003c\/strong\u003e Offers red, VU meter, or off illumination modes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe DR-1325.1 has a black V-Drive chassis with a QTD aluminum heat sink, LED VU meter, illuminated protection indicators, and screw-down connection points. Its nickel-plated brass terminals are designed for secure, corrosion-resistant power and speaker connections. The compact amplifier measures 8.0 inches long, 5.83 inches wide, and 2.2 inches high.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a ventilated location and do not mount it upside down. Use 4 AWG cable for the 12V and ground connections, use an externally fused power lead with a 60A fuse, and use up to 8 AWG speaker wire at the amplifier terminals. Connect a compatible RCA signal source, set gain from minimum during initial setup, and ensure the final subwoofer load is not lower than 2 ohms.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45622741827654,"sku":"DR-1325-1","price":122.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71S4AMkVDWL.jpg?v=1784372268","url":"https:\/\/audiowatt.store\/products\/crunch-dr-1325-1-v-drive-mono-subwoofer-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
