Good evening dear forum people, especially since I have already realized some CarHifi installations, I thought that with my 16 years I could earn something from just these (so far always for free for friends etc.) something. Now I would like to be interested in what you fundamentally think of this idea, what expectations I can have, how much I can “request” and how I “break” for what (per installation, per built-in radio etc.) … ? Like me, the problem of liability is there – or how do you see it? What if the car I have made an installation burns after half a year – even if I don’t bear any blame for it myself, especially since everything was covered by the cable cross-section and this was chosen on the basis of the required performance … ? Could one exclude or minimize a warranty/liability, then Felix would be obliged to write a sheet of information, such as if the system were not operated for too long without an engine?
