How to Solder an RCA Plug

Updated February 21, 2017

The RCA plug is one of the most common types of electronic connectors. Originally developed by the RCA company as a connector for hooking up phonographs to radio consoles, it is commonly used for connecting audio components like CD players to amplifiers, as well as for video signals.

Strip the insulation off of the end of your wire so that each lead has 3/8 to 1/2 inch of bare wire exposed.

Unscrew the protective shell (jacket) off of your RCA plug. Slide the shell onto the wire.

Hold the positive lead of the wire against the centre pin on the back of the RCA plug. Apply your heated soldering iron against the two until it is hot enough so that the solder touched to the wire will flow into the joint. When you've applied the solder, remove the soldering iron and allow the joint to cool.

Hold the negative lead of the wire against the tab on the back of the RCA plug. Apply your heated soldering iron just like in Step 3, and then allow the joint to cool.

Slide the jacket over the joints and screw it tightly onto the plug. Your RCA plug has been soldered.
