Basicaly my new headunit drains my battery flat in 4-6 days in off, I tried the yellow and red switch but it never worked to keep the headunit on. So I wired both the red and yellow directly to 12v, there are no shorts. But because the headunit is always on the battery drains in the time specified.
With my new job I might be using the car all week, otherwise not using it at all for a few weeks altogether, so when I jump in i got a flat battery, then shouting "FFS, back to public transport" any advice in regards to the battery issue or what i can do to prevent it?
Prefably the cheapest option, like a 2nd battery, better battery, limiting power to headunit when ignition off... I'll leave it to the experts
