The risks of installing your own auto sound system may be greater than you realize. The fact is that there are people that are professionally trained in the installation and proper handling of these delicate sound systems for a reason. If it weren't a difficult task they wouldn't be able to demand the rather hefty price tag that most installation centers charge. The problem is that mistakes can actually cost more than the installation. If you aren't one hundred percent certain that you can handle the installation process alone it is best to leave it up to the experts. To prove my point, I will give you my very own personal story of how auto sound system installations can go horribly (well, perhaps hilariously would be the better choice of words in my particular situation) of course. You see I wanted a CD player in my mini van about 13 years ago. This was back in the dark ages when these types of sound systems were still relatively new and on the 'cutting edge' when ...

In order to control electrical loads such as heating in the picture below using double pole switch. Double pole switch consists of four terminals. And electric heating load consists of three terminals. In the second switch terminal to get into each phase line (L) and the neutral line (N). While the other two terminals each connected to two terminal heating load. One other terminal on the body burden, directly connected to the grounding line.  a.
