Amplifier Aiyima TPA3116 2.1 case

thingiverse

This is a case for an Amplifier Aiyima TPA3116 2.1, a digital amplifier class D2 with three outputs: two for the left and right channels and one for a subwoofer. I measured several power supplies, and the input voltage ranges from 6V / 9A to 24V / 2.5A. However, the best and safest power supply is a laptop's 19V / 4A or 5 Amps connection. If the connector doesn't fit, you can cut it and make a direct connection to the PCB. The output is stereo with two channels producing 50 Watts each plus a subwoofer channel that produces 100 Watts. Recommended speakers for the left and right channels are 2x 4 ohm / 50 Watt speakers. For the subwoofer, a speaker with 2 ohms / 100 Watts is recommended. I purchased the PCB board from this link: https://www.aliexpress.com/item/DC12V-24V-2-50W-100W-XH-M139-2-1-Channel-digital-Subwoofer-Amplifier-Board-Chip-TPA3116D2/32574627375.html On the front panel, a small hole is visible on the left side. This is where an LED diode from the board should be inserted for optimal visibility. If you want to change it to a panel view,
