    Great sounds out of small package. I was amazed by the wattage and features this little guy packs.

    If I could give it zero stars. I would. Impossible to set up without taking it to a "professional" 0/10 wpuld reccomend. Its already a bad design that easily overheats. On top of the key comluter system that makes the amp impossible to set up. Its veen over two months and I still cant get this thing to work. Abkut to just throw it away

    Bought in may 2022, stopped working in September 2023, it has 12v power to the connection but the power light won’t turn on. At this price point I expect it to last longer than a year and a half
