I use it for about a year.
Cram it once, because of some jerk who pass derrire the sound while my back was turned and threw me gain and master background and 4 rsultat ct + 2 transistors right Resistors and a fuse. Fortunately trs simple manufacturing rpar I could with the help of a friend for about 20 very easy.
Trs if it works well, despite the abuse that I reserved. I always use the rgl three quarts see a bit more on the night complte trs and often a group lectrogne!
A I forgot, in bridge mode into 4 ohms. I think we can not do worse.
And that's everything that I find trs well as bought used 100.
So for me it is difficult to report qualitprix do better.
It remains even when a low-end amp I am aware.
17 kg for 2 * 350W??
But for the price hard to beat.
