How To Connect 12 Gauge Wire to Bose Speakers

Whether you want a small, low-end headphone set to an expensive home theater system, Bose is one of the best brands to get. It’s a trusted brand in audio equipment. A lot of audiophiles swear by their Bose speakers. For most consumers, Bose is also a popular brand because of their compact speakers that can blend in with most room designs. Don’t be fooled by their diminutive size, though. Bose speakers produce full-bodied sound, especially when setup correctly.

However, you will notice significant signal loss if you use the improper gauge of wires in connecting your speaker. For best results, follow the user manual. In most cases, a 12 gauge wire will give you best balance between signal, cost and availability.

This is especially useful if you need to extend the length of your speakers. While you can simply extend the existing cable on the speakers, you would surely get some signal loss. For best results, you will want to replace the entire length with a 12-gauge wire.

  • Cut the existing wire connectors from each of your Bose speakers. Don’t forget to leave about two inches of wire, so that you can connect the new cable.
  • Take out the insulation from the last ½ inch length of each remaining pieces of wire leading out from the speakers. You can use a wire stripper for this purpose. Or, you can simply use scissors. Just be careful to cut only the insulation, and not to cut through the copper wire.
  • Strip the ends of the 12-gauge wire with a stripper or with a pair of scissors. Strip it such that there is about a ½ inch length of exposed wire.
  • Twist together one lead wire from the Bose speaker to the bare wire of the 12-gauge cable. If you are using colored 12-gauge cable, be sure to match it with the wire coming from the speaker, for easy reference when you’re already connecting the speakers.
  • Do the same with the other wire leads.
  • Heat your soldering iron and prepare soldering lead.
  • When the soldering iron is hot, place it against one pair of twisted wires until the wires become hot enough. Touch solder onto the wires, and let it melt and flow to seal the joint. Take out the soldering iron and let the joint cool.
  • Do the same for the other connections.
  • Let all the joints cool. You will then need to wrap each joint with electrical tape to prevent short circuiting.
  • You can now plug the ends of the 12 gauge wire to the socket on your home theater system or stereo component.
  • After connecting, test the sound quality, whether it has degraded or improved.

Extending the cables on your Bose speakers can be fairly straightforward. Be sure to have all needed equipment on hand. Take care when working with a soldering iron, as the surface will be hot For best results, wear gloves and eye goggles, to prevent any burns or other injury while using molten soldering metal.
