How to Adapt a Speaker Wire to an RCA Jack

By Nichole Liandi

Most speaker wires connect to the terminals of the speaker by using bare wire connections. However, in some cases, there are situations where you'll want to adapt the speaker wire to RCA jacks. Most often, this occurs when you need to connect the speaker wires to an amplifier's RCA input jacks. The job isn't complicated and can be accomplished with some basic tools.

Things You'll Need

  • Wire strippers
  • RCA jack with removable cover
  • Soldering iron
  • Rosin-core solder

Step 1

Pull the two leads of your speaker wire cable apart by a distance of two inches. Remove a 1/2 inch of insulation from the ends of each of the speaker wires.

Step 2

Remove the cover of the RCA jack by pulling it off or unscrewing it, whichever is appropriate for your jack. Slide the end of the jack over the wire with the narrow opening going first.

Step 3

Place the positive lead of the speaker wire onto the center tab on the back of the RCA jack. The positive lead is usually marked with a set of "+" marks on the jacket of the lead, or is colored red. Heat the junction with the tip of your soldering iron and apply solder until it flows between the tab and the speaker wire lead. Remove the soldering iron and let the joint cool.

Step 4

Place the negative lead of the speaker wire onto the side tab on the back of the RCA jack. The negative lead is usually marked with a set of "-" marks on the jacket of the lead, or is colored black. Heat the junction with the tip of your soldering iron and apply solder until it flows between the tab and the speaker wire lead. Remove the soldering iron and let the joint cool.

Step 5

Slide the jacket of the RCA jack over the backside of the RCA jack and screw it on, if necessary.
