I am facing a strange problem with my car's electrical system in particular sound system. Its cultus 2006 and sound system has a JVC pre with 4 channel amp and 2 speakers and 1 subwoofer. The problem is that whenever I press horn, turn on roof light, switch on ac/heater the stereo restarts. Sometimes the stereo turns off and only turns on again when car is shutdown and ignition switched on again. Sometimes only subwoofer restarts. Its totally random. The electrician checked for stereo's and amplifier's connections but couldn't figure out why the problem is showing up. I even changed the stereo but the same is same. Whenever some other electrical component is switched on/off the stereo or subwoofer restarts
