Review on 🎶 12V Hi-Fi Car Stereo Amplifier with Digital Player, USB/SD/FM/MMC/DVD/MP3 Input Support by Sarah Codina

Does what it should. Works perfectly. I used it to name an electronic game. I use two CB Audio speakers and a 12 volt power supply with them. To the right of one of the speaker wire tabs on the back of the amplifier. There's a hum when you just use the volume knob, but when you use the remote to control the volume I didn't notice any hum. In order to use the remote I have found that you have to be close enough, 5ft, or it won't work. It's cheap and it works.
