I own this amp for a few months, bought around 400 euros in Germany, announced the appointment power as the first view, the breakdown is a little noisy, temperature after 10 hours: ambient temperature, it does not heat at all. Single fault, not the bridge at 4 ohms it can not bear the load, I tried one night by putting 2 subs and during low-intensive pieces, he would be safe. Otherwise this amp is really good, cheap and light.
