DC 12V-15V 25W~30W Subwoofer Amplifier Board Mini HiFi Class D Mono Channel Digital Audio Power Amplifier, Super Bass Amp Module, for PC Computer Desktop Speaker, Car Audio Speaker
- Pure Bass Output Design: This power amplifier board is designed exclusively for subwoofer bass output with no midrange and treble output, and it is recommended that the power supply be not lower than 9V to obtain larger power output. Flexible Power Supply Options: Power supply DC6.5-15V depending on the required output power, compatible with a power adapter, switching power supply, or battery with recommended current of more than 3A, featuring a 5.5*2.1DC socket or pad of welding wire for power input and a 3.5mm plug or pad of welding wire for audio input interface. Multiple Output Power Configurations: Test data shows VDD = 7.4V RL = 2 delivers 12.5W, VDD = 9.0V RL = 2 delivers 18W, VDD = 12V RL = 4 delivers 20W, and VDD = 16V RL = 4 delivers 32W output power. Optimized Speaker Compatibility: Recommended to use with a 4-5 inch, 4-6 20-50W subwoofer speaker for enhanced bass performance, with the upper crossover point set at 110Hz. Durable Construction and Compact Dimensions: PCB material made of FR-4 glass fiber board with 1.6mm thickness, board size of 1.57x1.65x0.78inch (LxWxH) excluding potentiometer handle length (potentiometer protruding length 0.59inch), onboard fixing hole diameter M3, and potentiometer mounting hole diameter of 0.28inch/7mm
