      Overall a good amp for the price but only for the price. The great thing is that its easy to set up and it has many pots to change the sound. Im not sure about the 100w on the sub-out tho. It more seems like 50w and the bass also starts to distort and is unuseable above 50-60% volume. Most 8" and 6.5" subwoofers will already be underpowered by those "100W" of bass. The 50w on the L and R channel seem legit, altough it still doesent get that loud on full volume. The bluetooth connection however is fantastic, speaker is in the first floor of the house, I am standing on the third floor with many walls inbetween and the connection is still perfectly fine.

      Tut was es soll. Keine Doku; Schiebeschalter zwischen den Potis ohne Beschriftung. Das Pairing/Umschalten zwischen Line-In und Bluetooth ist hakelig.
