1pc 2.1 Channel BL Digital Power Amplifier Module — and Low Tone, Super Heavy Subwoofer, Power A compact, power 2.1 channel digital amplifier module designed to deliver clear stereo sound plus powerful lowfrequency output for a super heavy subwoofer. The BL digital design provides efficient amplification with low distortion to improve clarity across highs and lows. Ideal for DIY speaker projects, multimedia systems, and small home audio upgrades where punchy bass and reliable stereo performance are required. Key benefits Drives a full 2.1 setup (left, right and subwoofer) from a single module — simplifies wiring and reduces component count. Delivers power output suitable for driving a heavy subwoofer, restoring deep, controlled bass that passive systems often lack. Digital amplification reduces heat and improves efficiency over legacy analog amps, making the module suitable for enclosed builds and compact installs. Improves overall sound balance by supporting both and low tone reproduction, so vocals and instruments stay clear while bass remains tight. Singlemodule solution (1pc) that is easy to integrate into existing speaker cabinets or DIY enclosures. Key attributes Functionality: 2.1 channel digital power amplifier module — stereo left/right outputs plus a dedicated subwoofer channel. Tone handling: Designed to reproduce both and low frequencies with authoritative lowend performance for subwoofers. Power profile: Described as ' power' and suitable for 'super heavy' subwoofer use, offering stronger bass drive than typical small amp modules. Form factor: Moduletype device (1pc) intended for installation inside speaker enclosures, audio racks or custom builds. Compatibility: Intended for use with passive speakers and subwoofers in 2.1 configurations and with common linelevel audio sources; pairs well with preamps, receivers, and media players when proper wiring and power supplies are used. Material and build: Module construction optimized for reliable electrical performance and compact integration (module form factor). Simple installation notes Mount the module securely inside an appropriately ventilated enclosure. Use a suitable power supply and wiring that match your speaker impedance and electrical requirements. Connect left/right speaker outputs for stereo and the dedicated sub output to a compatible passive subwoofer. Adjust source level and any available tone/level controls on your preamp or source to match desired balance between stereo and sub. Typical use cases Home multimedia upgrade: a weak factory amplifier in a bookshelf or desktop speaker system with this 2.1 module to add a dedicated sub channel and noticeably deeper bass. DIY powered speaker/subwoofer: Integrate the module into a custom cabinet to create a compact active 2.1 system with strong lowfrequency performance for music or home theater. Small venue or hobby audio projects: Use as the amplification core for hobbyist PA boxes or studio monitors that require a dedicated sub channel and higher bass output. What this module solves Restores and extends lowfrequency impact where existing systems lack bass authority. Simplifies 2.1 system builds by combining stereo and sub amplification into one efficient digital module. Reduces heat and footprint compared with larger analog amplifiers, allowing tighter integration into cabinets and custom enclosures. Who should consider this module Audio hobbyists building or upgrading custom speaker systems. Home theater and multimedia users who want stronger subwoofer performance without a separate sub amp. Smallscale installers and DIYers seeking an efficient 2.1 amplification solution with clear /low reproduction. This 1pc 2.1 Channel BL Digital Power Amplifier Module focuses on delivering power and heavy subwoofer drive while preserving and low tone clarity — a practical choice for anyone needing a compact, efficient, and capable 2.1 amplifier solution.
