I have a problem in the multimedia system in my car. Whenever I leave the car off for two days (like the weekends for example), the multimedia system drains the battery and, subsequently, I have problems in starting the car. So, every weekend I have to open the front hood, detach the multimedia system fuse and on Monday morning I attach the fuse back again. Is there another way to do this without opening/closing the hood every-time? I tried to look at the configuration of the multimedia system, but there is not totally shut off option.

Is there other solution for this problem?

If it was me, I'd wire the live supply to the multimedia system to the switched live (ie the 12V when the key is on) and not always live (direct to the battery)

That is a simple fix.

It does seem a bit strange that the current draw from the multimedia system is so high when off, though, so you may want to check the system and see if it is behaving correctly. All the systems I have had, even my current one which runs a Debian audio server, will power down to zero current draw after a time period of no activity.

It seems very odd that your system drags so much of power . I would not recommend to directly connect to the ignition switch. Instead you can attach a relay in the following manner: (apologies in advance for poor drawing )circuit
