Key benefits Clean, reliable stereo amplification for 4–8 Ω speakers: delivers up to 100W x 2 (4 ohm/32V load) to drive bookshelf speakers, car speakers, or small PA cabinets without excessive distortion at moderate levels. Wide powersource compatibility: accepts a 12–24V input range so it works with typical car, motorcycle, RV, marine, and portable battery systems. Stable, dedicated amplifier circuitry: built around the TPA3116 DC power amplifier chip for consistent performance and predictable power delivery. What this product does Provides stereo power amplification for speaker systems with terminating impedance between 4Ω and 8Ω. Converts a 12–24V DC input into power audio output, capable of a maximum 100W to each channel under the specified 4Ω/32V condition. Why this solves common problems Replaces weak onboard or small amplifier modules that can't drive lowimpedance speakers to useful levels. Supports vehicle and portable audio applications that operate on 12–24V systems without requiring a separate voltage power supply. Simplifies DIY speaker or retrofit projects by matching common speaker impedances and voltage sources. Important attributes (ataglance) Terminating Impedance: 4Ohm – 8 Ohm MAX Power Output: 100W x 2 (4 ohm/32V Load) Power amplifier chip: TPA3116 DC Input Range: 12–24V Function: Stereo power amplifier for driving compatible speaker loads Compatibility: Works with speakers rated 4–8 Ω and power systems providing 12–24 V DC Practical use scenarios Car or marine audio upgrade: Power factory or aftermarket 4–8 Ω speakers directly from the vehicle's 12V/24V electrical system for louder, clearer sound. DIY activespeaker builds: Use as the amplification stage for a pair of bookshelf or monitor speakers powered from a 12–24V supply. Portable PA or practice rig: Drive compact speaker cabinets from battery or vehicle power during outdoor events, rehearsals, or field work where mains power is unavailable. Notes on selection and setup Match speakers to the stated terminating impedance (4–8 Ω) to avoid overload or reduced performance. For maximum rated output, a stable 32V supply is referenced in the MAX Power Output condition; realworld performance will depend on supply voltage and speaker efficiency. Follow safe wiring and cooling practices to maintain reliability when operating at higher power levels.
