Review on Facmogu V10 Car Power Amplifier: 2x20W Black V4.0 Bluetooth Stereo Digital Player for Car, Motorcycle & Home - USB/SD/FM/DVD/MP3/MP4 Support (No Power Adapter) by Scott Channell

Nice lightweight amplifier/receiver/sound system without speakers. It has everything I was looking for in a small amp box. The device has bluetooth which works very well. It features USB playback port, USB charging port, TF card port, AUX-IN port (3.5mm), rear line port with RCA jacks, remote control and FM radio. He has several problems. a few features of the device that made me think about returning it. I could. The volume output of the device can only go up to half. If you turn the volume up more than half, the device will shut down or try to restart, and sometimes it will make a loud, continuous beeping sound. It plays very well at half volume or less. It's loud enough for what I need. A savvy, possibly bored engineer thought it would be a good idea to add those pointless and annoying blinking LEDs on the front panel. I rarely look at the device, but even so, these lights serve no useful purpose. I covered them with black tape. The remote control is small and has a short range of less than 2 meters. FM radio setup is cumbersome and tricky. Basically, I like the device. It is small in size, has many features and is very versatile. It doesn't heat up does not heat up and has no background hum. But the lack of loud audio is a problem. I feel like for $18 you can't expect more.
