How to Convert Wired Speakers to Wireless. Step-by-Step Guide

Are your old analog speakers collecting dust at home? We’ve got great news –– you can breathe new life into your outdated speakers by converting them into a wireless sound system.

With the help of a wireless speaker kit, you can easily convert wired speakers into a wireless set. Wireless speaker kits transmit audio signals via radio frequency waves or Bluetooth.

You may also need to incorporate an amplifier into the setup to successfully power up your speakers.

In this article, we’ll give you a few pointers on how to pick the best wireless speaker kit. From there, we’ll give you a step-by-step guide on how to convert wired speakers to wireless.

Let’s get started!

How to choose the best wireless speaker kit?

Wireless speaker kits are used to stream audio from wired speakers with the help of a transmitter and a receiver.

Before you buy a wireless speaker kit, you should know that there are different types of this product.

Type of wireless kit

You will find four primary types of wireless speaker conversion kits:

  • With built-in amplifiers
  • Without a built-in amplifier (transmits and receives audio signals only)
  • Transmits radio frequency signals (RF)
  • Transmits Bluetooth signals

Generally, speakers without built-in amplifiers are cheaper and require lower power outputs. However,  if you have speakers that need higher output, you’ll need a wireless conversion kit with built-in amplifiers.

Note: You can also use a chromecast. We have a guide on using chromecast with bluetooth headphones. You can use the same method with bluetooth speakers as well as 2 way & 3 way speakers

Range of Transmission

To choose a wireless speaker kit, you’ll also need to consider the range of transmission. Most wireless kits have a transmission range of 100 to 300 feet.

We recommend the Amphony 1800 wireless speaker kit which boasts 300 feet direct range and 100 feet when blocked by walls and ceilings. 

What’s more, audio signals are transmitted without audio compression. Its built-in amplifiers ensure that there is no distortion. 

Ease of Setup

Another factor to think about is the ease of setup. 

The Rocketfish RF-WRSK18 is one the most straightforward wireless kits we found. While other wireless kits require users to set up the transmitter and receiver channels, the Rocketfish automatically detects the transmitter-receiver pairs.

Step-by-step Guide: How to Convert Wired Speakers to Wireless?

Turn your outdated speakers into a modern sound system with these steps:

Step 1: Choose your Wireless Speaker Kit

Most wireless speaker kits are composed of three main parts: a transmitter and two receivers. Aside from that AC adapters and wires are included for the power output.

We also mentioned that there are three main types of wireless speaker kits.

But to simplify your choice, you can start by deciding whether you need a kit with a built-in amplifier. Kits with built-in amps are a good choice if the power output from your receiver is low.

If your speaker is active, you don’t need to get a speaker kit with an amp. 

The  BIC America is a great choice for wireless speaker kits with no built-in amps. It’s easy to set up and it boasts a transmission range of 60 to 80 feet. 

You will need to check the inputs on your transmitter and receiver as well. If your pre-outs are available on your receiver, then you can connect RCAs directly from the receiver to the transmitter.

Otherwise, you’ll need to use regular speaker wires for the input. You can also use a line-level adapter to convert speaker-level input to RCA level input.

 It’s true that wireless speaker kits still use wires. In essence, though, the speakers become wireless because the sound system isn’t directly attached to the source. Instead, the audio signals pass through the amplifier.

Step 2: Connect the Transmitter

The next step is to connect the transmitter to the Stereo Out or built-in amplifier. Transmitters will send the audio signals wirelessly through radio frequency or Bluetooth.

The input options for the audio signal will depend on the kit you choose. Generally, you will find these options:

  • Speaker wires: Standard connection from receiver outputs to transmitter inputs:
  • RCA: Connection from receiver pre-outs to transmitter RCA input.
  • AUX 3.5mm: For transmitters with 3.5mm input, use an RCA to 3.5mm adapter to connect receivers to transmitters. This setup will require additional power through an amplifier.

Step 3: Connect the Receiver

Depending on the wireless kit you chose, the setup for receivers vary:

For speakers without an internal amp

This scenario is best for passive speakers without an internal amp or a power source.

In cases where you’ll use a separate amplifier, connect RCA from the receiving unit to the amplifier. Then, connect the speaker wires from the amp to the speakers.

Connect the receiver to the AC adapter, then plug the AC adapter into a power source.

For receiving units with an internal amp

This case isn’t common, but some receiving units already have a built-in app.

Connect the speaker wires directly from the receiving unit to your speakers.  

Plug into a power outlet afterward.

For speakers with an internal amp

Speakers with an internal amplifier are called ‘active speakers.’ They can be directly plugged into a power outlet.

Simply link RCAs from the receiver to the speaker to stream audio wirelessly.

Step 4: Test your Setup.

If you’ve completed steps one through three smoothly, your new wireless speaker should work! 

These tips should help you test your sound system:

  • If there is a static sound or if audio is delayed or muffled, check the connection between the transmitter and receiver.
  • Manually set the channels between the transmitter and receiver to see if sound quality improves.
  • Adjust the sound levels by tinkering with the amplifier and receiving unit. The final audio should sound like your wired speakers.

If you still have the energy & are up for a challenge, how about download songs from Tumblr and give them a try?


Turning your speakers wireless will allow you to stream music and media from Youtube, Spotify, Soundcloud, and more. We can even help if Spotify randomly logs you out constantly.

To turn your old analog speakers into clutter-free and convenient wireless sound systems, you will need a wireless speaker kit.

These wireless speaker kits transmit audio signals via Bluetooth or radio-frequency. You may need to get a wireless speaker kit that includes an amplifier because not all speakers provide electrical power.

Depending on your wireless speaker kit, you will need to connect the transmitter, receiver, and amplifier.
