We fixed a radio installation in a 2002 Honda Civic recently. The original installation was done with wire nuts. While wire nuts work well in homes they are not recommended for mobile installations. The biggest reason is that wire nuts are designed to be used with solid core wire, not the stranded wire found in vehicles. A wire nut will not thread properly into the type of wire used in cars, rather it will crush the wire making the connection brittle and a likely point of failure. This failure could be the sound cutting in and out, blown fuses or even an electrical fire.
The safer and proper solution is to solder these connections and isolate them with shrink tubing. This is ultimately the safest and most reliable connection in a vehicle and is how we approach every installation at Mobile Edge.
Mobile Edge offers all types of audio upgrades and we install them to strict industry standards. If you would like to learn more, we would love to have you stop in and allow us to show you around.
