Review on TPA3116 200W HiFi Bluetooth Amplifier Module - Dual Channel 100W+100W AUX Digital Home Audio Amp Board with LC Filter DC8-24V for DIY Speakers by Thimothy Purnell

I use it for the audio system on my UTV Polaris Ranger. I used to have something like this in the glove box, but the old system was so clunky that it took up the entire glove box. This is a really nice amp, it's almost a shame to hide it in the glove box. Pros: - Very compact, much smaller than the old system I installed. I can install it behind one of the dash holes, which makes the glove box usable again. - more powerful than the old amp, the old unit was advertised as 200 watts, but this one is undoubtedly 2 times more powerful - you can buy it. works in a wide voltage range of 5-27V, which makes it more flexible. In theory, this device can be powered by 4 18650 batteries - the bluetooth works fine, it connects automatically when the key is turned on. With the old system I had to leave a phone in the cup holder or the audio would cut out. With this system, I can move a few feet from my UTV and the audio will not be interrupted. Cons: - really nothing that I can think of. If I'm very picky this doesn't work for every project as it's not fully closed, this can easily be solved with a small project box. I'm so impressed with this little amp that I'm planning to build a system for my patio that has the amp embedded in the wall.
