Hello now with the amplifier so far all LS outputs (the system has the rear right the amplifier installed and all LS are active ! Front doors 3way and rear 2way) found, but the inputs funk. not right. There only a quite high sound signal arrives. Even if I disconnect the two main plugs, then nothing at all. Does not come from the control unit a full range signal to the amplifier ? Where does the LS control take place ? On the radio or amplifier ? To another amplifier r to be able to follow I need a full range signal ! Can someone help me there ? Thanks in advance !
