Hello dear forum members I have a little Proplemschen. I recently installed a car radio with power amplifier. Power amplifier nicely connected with remote and it went out even if I pull out keys so well. So that with my radio the transmitters or bass settings remain stored I soldered the cables! Red with yellow and yellow with red. So the transmitters have always been saved and everything is in order. BIS I have been propleme for about 5 days with the Battery it is ALWAYS empty and is not enough to start from the engine as soon as I have not driven for 1 day anymore. I have finished the final stage but still is still so. What can this be? I just wanted to start again and engine is not going to go again it was not even enough juice there to close the central transmission. What I noticed though I pulled out keys was car radio still on (which it was not before otherwise always gone with) and the Amatu the displays were very light only when I have closed the car radio again everything went out of power… What can that be?
