Review on 🔊 AIYIMA DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 50W+50W+100W (Bluetooth Amp) by Chris Cooper

Pretty decent amp. In any case, think of it as a 24V amp that can be powered by a 24V power supply or batteries. On batteries it will still play when your batteries are down to 12v but with clipping at any significant volume. big; You get a stereo channel volume control and a tone control. The .1 subwoofer features volume and tone controls, as well as a push button master volume control that you press and hold to pair. 24V is a must if you want to pump a lot of sound. I'll upload a video of him playing something with bass and maximum volume with the cheapest speakers you can buy on Amazon so you can see this amp really shines at 24V. Expect terrible phone audio capture, but it's crystal clear and full volume with no clipping in person. Haven't tried the other inputs but will have something to do when I get bored.
