Find modules based on TDA, LM, or STMicroelectronics ICs, or complete packages from brands like Adafruit, Texas Instruments, and locally sourced kits. Check datasheets for compatibility, voltage supply (5V, 12V, 24V), and whether a heatsink or enclosure is required.

How to Choose the Right Audio Amplifier

Selecting an appropriate amplifier for your project or installation in South Africa involves careful consideration of a few key factors:

• Required Output Power: Match your speaker's RMS rating; most projects use modules rated 3-30W per channel
• Impedance Matching: Ensure the amplifier supports your speaker's Ohm rating (4Ohm, 8Ohm, etc.)
• Voltage and Power Supply: Check if you need a single-rail or dual-rail supply. Most modules require regulated DC and clearly state voltage/current needed (e.g., 12VDC, 2A)
• Input Types: Stereo line-level for computers/audio sources versus header or onboard mic options for custom circuits
