I regret not having come forward on this site because I would not have bought this amp because the power is effectively zero trs is the first failure since its purchase power LEDs then I made an animation for friends then the other buyers as a cot HS after 4 hours of operation and 2 hours after another cot and more it seems to me that there are no protections for one of the speakers sold with died !!!!! rponse of the e-start the vendor "you do not know you used an amp" so 450 euro for my loss!! because it does not take under warranty, I opened the photo and as nothing in it to finish the double CD of the same brand is trs long to find the tracks of the cd serious! @ +
