Quality & Clarity....WoW!
I am not a technician but just a music lover, so thought of trying myself with some extra speakers lying down at home. Believe me, both the quality and clarity of sound system is top notch. No regrets really. Bluetooth 5.0 connectivity is great.

Generic amplifier, different from what's advertised in the image
I received an amplifier which is different from what's shown in the image. The amplifier I received has Bluetooth, AUX and USB as input and transmits BT-BLE-APP when turned on but there is no app that I can use to control the amplifier. I tried all the common amplifier apps like Wuzhi and synlink but nothing worked. I sent multiple communications to both Amazon and the seller but received no response and now I'm stuck with a useless amplifier. Won't recommend this to anyone.

Works surprisingly well.
Very surprised and pleased with the sound quality. Clear as a dadgum bell, once I got the proper power supply running to it. Yes it runs on just 12 volts, but you need a fairly powerful 12 volt power supply. Volume goes to 10,wish it went to 11. Lol. I recommend this little amp, and would buy it again.

Absolute little rager
This little thing bangs!! Replaced a smaller Bluetooth receiver with this. Threw in a little shallow sub. And get a perfect sound. Very impressive how loud the speakers can jam with this little guy!

Not bad for the money, Bluetooth could be set up differently though.
This is a really surprising little unit! Packs a good punch. It sounds great, two 6.5 components with tweeters and a massive audio hippo 8, it is power hungry. I cant believe it pushes my sub, it doesn't pound but wow it sounds good! For sure use a good power supply for wall plug in or 20v drill battery.
