Its a different type of amp using high rail voltage instead of typical korean design meant to wire extremely low and run on 16/18volt systems(which no normal bassheads do anyways). I was sketched out at brazilians before too and was hesitant to try it but after having some leftover money and a spare dc 3.5k to fall back to just incase i didnt like it or if it blew, I took a gamble and tried it out. It was surprisingly beefier and more sturdily built than i expectd(i was expecting some flimsy piece of metal). It was pretty solid and heavy in feel. Just not big at all like we are used to with korean amps.
Output and SQ wise(bass sounded cleaner with more power i'm guessing), it was in every way was superior to the DC 3.5k performance wise, stayed cool as a feather too with the push pull fan configuration. I had to sell an amp and between the dc 3.5k and the banda, I sold the dc.
The gain knob is extremely sensitive though. When i set the amp for 4.5k rms, The gain was at 10% and the sub level was down to -3db and I already reached proper ac voltage.
idk why you would even come to any conclusion on a junk video showing nothing.
