1/4 speaker jack, which is positive and negative?

The positive terminal (+) is connected to the red wire, and the negative terminal (-) is connected to the black wire.

How do I check if a speaker wire is positive or negative?

Red wires are usually positive, while black wires are negative. Silver wires are usually positive, but sometimes negative. Copper wires are always positive.

Positive wires are usually marked with “+” signs. This kind of mark is used when the positive wire is connected to a battery.

How to connect speaker wire together extending speaker wire

Speaker wire should be connected using crimp terminals, because they give long-lasting, professional results in minutes, instead of hours or days.

A wire is very reliable and easy to use. You can buy crimp tools and connectors easily. Only a few steps are needed: cutting the wire if needed, stripping the wire, and connecting the wires.

Things you will need:

  • Cutting pliers.
  • Automatic wire stripping tool with a cutter section.
  • Wire strippers with a cutter.
  • Needle nose plier with cutting section.
  • Crimpers with a cutting section.
  • Utility scissors.

We recommend using wire cutting pliers as these are capable of cutting a wide variety of wires. For typical speaker cables or wires such as 18-gauge, the wire cutting features on some hand tools work fine.

What to know before stripping speaker wire the first time

Crimp connectors are used to join wires together.

Crimps come in various sizes and shapes, but most commonly there are two types: barrel and ring.

Barrels are usually larger than rings and are used when more space is needed to fit the connector into the wire. Rings are generally smaller and are used when less space is available. Crimping tools are also available. Some crimping tools have a built-in light source that makes it easier to see what you’re doing. Crimping tools are made for different purposes, such as stripping wire or connecting wires together. You can use them to make connections by hand or with pliers.

Crimp connectors should be used with speaker wire, but they require some skill to use properly. You need to strip enough wire to leave about a three-eighths inch for crimping. Then, you need to crimp the connector onto the wire using a tool.

Crimping speaker wire correctly is easy if you follow these steps.

First, strip the wire leaving 3/4″ to 1/2″ bare speaker wire exposed.

Then tightly twist the wire so it fits into the terminal properly.

Insert the wire into one end, push it into the metal contact, place the connector into the crimping tool, hold the tool near the end of the contact, and crimp very hard to make the connection permanent.

Speaker wires should be straight and smooth. You should hold the connector firmly but not too tight when pulling the wire. When you pull the wire, it should stay put. If it comes loose, you crimped it improperly.

Crimp-type connectors come in standard colors for the gauge they fit. They include the recommended size range. Blue crimp-type connectors work well with 18 AWG speaker wires.

Wire nuts are more expensive than solder, but they are much better at connecting wires. Solder is cheaper, but it isn’t as reliable. When you connect wires with solder, there is a chance that the joint could come apart if the wire moves or gets pulled too hard. To make sure your wires stay connected, use wire nuts instead of solder.

Solder vs crimp terminals for connecting speaker wire

Solder is used to connect wires permanently. It is a very strong connection but it requires some work and patience to make it happen. Quick disconnects are used to connect wires quickly and easily. Speaker wire connections are different depending on the type of speaker.

You need to check before you start.
