It supplies up to 300 watts RMS to a 2-ohm load, giving an aftermarket bass setup dedicated amplification without requiring a multi-channel amplifier. Its mono design keeps the focus on low-frequency reproduction for music systems that need added bass impact.\u003c\/p\u003e\u003cp\u003eThis amplifier is suited to drivers building a straightforward subwoofer upgrade or adding bass to an existing factory or aftermarket stereo. Both high-level and line-level inputs support integration with a range of source units. The included high-level input cable is useful when connecting to systems without dedicated RCA preamp outputs.\u003c\/p\u003e\u003cp\u003eThe STAGE A3001 is engineered for subwoofer duty, with a specified frequency response of 10 Hz to 320 Hz. A variable low-pass filter allows the subwoofer’s upper-frequency range to be adjusted from 32 Hz to 320 Hz. Bass EQ settings at 45 Hz provide further adjustment for the vehicle, subwoofer, and enclosure combination.\u003c\/p\u003e\u003cp\u003eIts compact 50 x 145 x 241.6 mm chassis is designed for installations where amplifier space is limited. Input sensitivity controls help match the amplifier to the signal level supplied by the head unit. A phase selector provides another setup adjustment when blending the subwoofer with the vehicle’s other speakers.\u003c\/p\u003e\u003cp\u003eThe amplifier includes protection circuitry for DC, overvoltage, undervoltage, overcurrent, and overheating conditions. A power\/protect indicator provides operating-status feedback. Use the STAGE A3001 with a properly wired 2-ohm subwoofer load and appropriate fused power wiring as part of a complete car-audio installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300W RMS Mono Output:\u003c\/strong\u003e Delivers rated power to a 2-ohm subwoofer load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass D Design:\u003c\/strong\u003e Compact mono amplifier format for subwoofer applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Line-Level Inputs:\u003c\/strong\u003e Supports factory or aftermarket source-unit connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts subwoofer crossover frequency from 32 to 320 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass EQ At 45 Hz:\u003c\/strong\u003e Offers 0 dB, 6 dB, or 12 dB settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e Monitors electrical, thermal, and short-circuit-related conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STAGE A3001 uses a compact black chassis with grooved detailing, silver graphics, an anodized JBL badge, and orange end-panel accents.
