AK-380 USB SD BT.C FM AUX Audio Power Amplifier 400W+400W 2.0 CH HiFi Stereo AMP Speaker Bluetooth 5.0 Amp Receiver with 12V 5A Power Supply,Remote Control,FM Antenna for Car Home Bar Party

I've had this amp for several years and it has worked as advertised. It's hooked to bookshelf speakers in my shop and can get very loud if needed. All functions work however the only flaw is that once you scan the FM channels you cannot delete any channels so channels further away with static cannot be deleted so you have to scroll through them all to get to a good station.

This little amp sound great and works flawlessly. Bluetooth connects faithfully along powering up . Plenty of power for reasonable volume levels

With a coupon this was less than $30, and was well worth it. I needed a new FM tuner for my garage which has a speaker in the ceiling. The old tuner was failing and I also had a small bluetooth amplifier that it fed into before sending output to the speaker. The amp was fine but the tuner was having issues. This allowed me to replace both with one device and have both bluetooth and FM radio like I had before, but in a much more compact package. The tuner works great inside my garage and I tested the bluetooth with my phone and it connected easily. The only reason I deducted one point is that the FM tuner doesn't allow you store favorite stations in memory. It simply has a function to scan the local area for strong stations and automatically store them. I think it allows up to about 30 stations to be stored. In any event, I was disappointed that storing stations in specific memory slots wasn't available as it seems to have been a standard function of any digital tuner (even old analog tuners!) for decades. However, one feature that made this less annoying was that the unit appears to remember which mode it was in (line input, radio, or bluetooth) when it's turned off and then back on again. Since I mostly listen to only one radio station, I can just leave it set to FM mode and that station, and it seems to restart in FM mode and still tuned to the last station. So I can just turn it on and not have to fiddle with it each time I am working in the garage. It would have been nice to easily be able to switch between my three favorite stations, but it will certainly do. Otherwise, the sound quality was fine and the volume control knob worked properly. It has good strong volume which I didn't test for its full capacity as I don't need too much volume for my one stereo ceiling speaker. It did have stereo speaker wire terminals on the back that I connected to my speaker, and a wire antenna was included for the FM, which easily picked up many of the local stations. The instructions are fairly minimal, but enough to get me started with the functionality I needed. The build quality seems fairly sturdy with the metal case which has flanges with holes for easy mounting.

Very happy with this amp. Inexpensive, compact, and loud without distortion.

I have some extra computer speakers from a dead computer set. Wife accused me of being a hoarder, there is some truth to it but these were good speakers. I got this and hooked those speakers up to it and they sound great when I am in the garage. I just leave it out there. Didn't want to put a good set out there and this was perfect.
