I have let me off the shiny number dazzling 300 (watts). Thought was the small to replace my old amplifier, the subwoofer to has fired and unfortunately is no longer peep from him. Since the 600 watts or were so for me anyway too much, I gave the little new a chance. In the car one has so much noise and since I need yes no High Class Amplifiers for hundreds. I was surprised then that the Dingchen is so small. And as I hang now the thick + and - cables to the wires from the McFun? OK tuned leave everything at the old amplifier and the tiny wires just to terminals. Then off we went ..... yes what? Hello subwoofer, where are you? Lightweight rumblings can be heard, more not. Everything at maximum volume and still almost nothing. Time read on the net and at Ciao: Aha, someone has measured. 2x150 watts are anyway the Maximum values, 2x30 watts (RMS or so) should be done really, really delivers Ding seemingly 2x15 Watt and not bridgeable. A channel of cheap car radio brings 30-45 Watt, as the small McFun can not keep up and have to go back to the dealer. One point there are a minimum and a bonus point because I've read me (perhaps because since all big 300 watts it is) and the part for scooter riders should be great. For The Car goes the no. Dear traders, but not take the great-sounding numbers or praises the thing not as a full-fledged car amplifier on, I need you but then only with dissatisfied Customers like rumschlagen me.
