How to Hook Up Two Amps with One RCA Jack

The RCA jack is the standard connector for audio signals. It is also a phono jack, phone jack, or tip-ring-sleeve (TRS) connector. The name “phono” comes from being used initially to connect phonograph players to amplifiers. The RCA jack has three parts: the tip, the ring, and the sleeve. The tip is the end of the plug that goes into the socket first. The ring is in the middle, and the sleeve is on the outside. 

RCA plugs and jacks are used in various applications, including home stereo systems, car stereos, and professional audio equipment. They are also connected to video equipment, such as camcorders and DVD players. One of the most common uses for the jack is to hook up two amps.

Putting the RCA Jack to Use: Hooking Up Two Amps

If you want to hook up two amps with one RCA jack, you need to use a Y-connector. A Y-connector is a cable with one RCA plug on one end, and two RCA plugs on the other end. To use a Y-connector, connect the single RCA plug to the output of your first amplifier, then connect the two RCA plugs to the inputs of your second amplifier.

Remember that you will need to have separate left and suitable input jacks on your second amplifier for this setup to work correctly. If your second amplifier only has one input jack, you can use a mono-to-stereo adapter.

Tools and Materials Needed to Hook Up Two Amps with One RCA Jack

  • Two amplifiers
  • One RCA cable
  • Speaker wire
  • Electrical tape
  • Wire cutters

Few Instructions to Help

First, you will need to disconnect the negative battery terminal in your car. That is to prevent any potential electrical shocks. Once that is done, you can begin connecting the two amplifiers. 

Take the RCA cable and plug one end into the first amplifier’s “line out” port. Then, take the other end of the RCA cable and plug it into the second amplifier’s “line in” port. Make sure that both amplifiers are turned off before doing this.

Next, you will need to connect each amplifier to its respective speaker. For this, you will need to use the speaker wire:

  1. Cut two pieces of speaker wire, each long enough to reach from the amplifier to the speaker.
  2. Strip about a half-inch of insulation off of each end of the wire. Plug one end of each wire into the “speaker out” port on each amplifier, and then screw on the binding post to secure it.
  3. Take the other end of the wires and twist them around the metal terminals on your speakers.

Once everything is connected, you can turn on both amplifiers and test to ensure that everything is working correctly. If everything sounds good, then you are all done. Just be sure to tuck away any loose wires and tape down any sharp edges so that nobody gets hurt.

Now that you know how to hook up two amps with one RCA jack, you can enjoy your music without worrying about sound quality. That is a great way to get the most out of your audio setup and make sure that everyone can enjoy the music as much as possible.

 How to Hook Up Two Amps with One RCA Jack

The steps are essential because they ensure that you connect the amplifiers correctly and that everything is working correctly. By following these steps, you can be sure that your music is playing perfectly and everybody enjoys that: 

Step One

First, you will need to gather all of the necessary items. You will need two amplifiers, one RCA cable, speaker wire, and some electrical tape. Once you have all the items, you can begin hooking everything up.

Step Two

The second thing you will need to do is connect the RCA cable to the first amplifier. Once the RCA cable is connected, you can connect the other end of the cable to the second amplifier. Make sure that both amplifiers are turned off before connecting anything.

Step Three

Now that both amplifiers are connected with the RCA cable, you can now start connecting the speaker wire. Start by running the length of the speaker wire from the first amplifier to the second amplifier. Once you have done this, you can connect the other end of the speaker wire to the positive terminal on the first amplifier.

Step Four

Finally, you can now turn on both amplifiers. You may need to adjust the volume levels on both amplifiers to equal. After doing this step by step process, you can sit back and enjoy your music.

Summing Up

In conclusion, by following the simple steps and using the proper tools and materials needed you can better understand how to hook up two amps with one RCA jack. You can be sure that your system will run smoothly and sound great. 

While there are some minor disadvantages to using a splitter cable or daisy-chaining amps, these methods are still the best way to get great sound without purchasing additional equipment. 

Buy the system and level up its worth. Connect several speakers to your amp. We hope this guide will help you in a better way to hook up two amps with one RCA jack. 


How do you amp up with an RCA jack?

It can be pretty challenging to have two amplifiers but only one input for everything to go through smoothly. The solution? Connect your RCA jacks (which connect directly into the speakers) with an appropriately sized splitter cable.

How to split RCA cable to connect two amplifiers?

You can use either a splitter cable or an RCA hookup wire to connect two amplifiers. With the first method of connecting splitters to outlets, plug one end into each amp’s input and output plugs, respectively, then attach them with twist locks at both ends for extra security.

In most cases, this will work well because it doesn’t require much manual strength when pushing down on these buttons. 

What are the disadvantages of using one RCA jack for two amps?

If you want to safely connect more than one amplifier, then this is not the way for you. For example, a single RCA jack was made with just enough power supply for ONE amp. But if we split it and put two amplifiers into each side of our speaker wire (or another audio signal distributor), both will share what little juice that comes out from where they’re connected on an individual channel. This means less efficiency overall. 

Where do I plug RCA cables into the amp?

If you are looking for an easy way to connect your amp with the help of RCA wires, then this is perfect. You will require two cables to achieve these results, and they can be purchased at most stores that sell electronics equipment.
