Big sound in a small package.
Color: Silver
Amazing output for a tiny receiver. Very impressed.

good cheap amp
Color: Silver
It's a good amp. It's cheap. The Bluetooth works for modern phones but not good for connecting old Bluetooth devices from 10-15 yrs ago. 5* can't complain at this price.

The Right Choice!!
Color: Silver
I have this hooked up to a small Episode ev-06 sub-woofer and two bookshelf sonys. The sound that this is producing is incredible and powerful!! The bluetooth connected easily as well. I have to give this 5 stars all the way!!

RockVille Bluamp 21 great value.
Color: Black
Great little unit for the money. Fast shipping. Works perfectly as advertised. This little unit has a lot of bass.Using it with 6ohm speakers sounds really good. Bluetooth works perfectly with pretty good range.

Good Bluetooth receiver
Color: Silver
Paired this with two 6x9’s and a 12” sub to convert my 1938 Jukebox to Bluetooth. It was very simple to connect to other devices. Sounds great and has a pretty long range.

Works great
Color: Black
The media could not be loaded. Powers two 4ohm speakers & does the job well! The knobs are a kind of okay feeling but expected for the price. Bluetooth is great on this. Overall really like for my setup.

Great power from sub output
Color: Silver
The media could not be loaded. I mainly bought this for its passive sub output. I have to desktop speakers hooked up to left and right channel. This video wasnt even full power on the sub. Close but not all the way. Definitely makes is rated power! 70 watts rms to the sub at 4ohms is not bad at all and these lowerer power 8s love this amp ... show more
