The Sintoamplifier arrived with a short circuit in one of the audio outputs and the ignition was protected and turned off ..... this problem was corrected, but it seems that I misplaced a replacement of the audio outputs and the equipment sounded fabulous ( bad audio) and it was protected and turned off said OverLoad (overload) I removed the amplifier system and with an audio plotter I pre-amplifiers working well for a while ... but then turned off ... turned on the power red and brequeba ... but now nothing starts! I request diagram or help with this device ...
