The AIYIMA A1001 is a compact mono Class D amplifier built on the TPA3116D2 chip, rated up to 100W into 2Ω, with a switch between subwoofer mode (40–300Hz cutoff) and full-range mode. It suits desk and home-theater setups that need to power one passive subwoofer or one passive speaker from an RCA line source.

Who the AIYIMA A1001 is for

  • Adding a passive subwoofer: In SUB mode, the SUB FREQ knob sets the bass cutoff anywhere from 40Hz to 300Hz with a -12dB slope.
  • Powering one passive speaker: Switch to full-range mode to drive a single speaker across 20Hz–20kHz (±3dB).
  • Low-impedance drivers: It handles 2–8Ω loads and is rated up to 100W into 2Ω.
  • Small desks and shelves: The case measures 118.5 × 98 × 33mm without knobs, and a 24V DC power adapter is included.
  • Skip it if: you need stereo, Bluetooth or an output for a powered subwoofer — it is a one-channel amp with an RCA input and speaker terminals for passive drivers.
