How To Hook Up Two Amps With One RCA Jack: Ultimate Guide

Connecting multiple amplifiers through a single RCA jack is a straightforward process that can be achieved through RCA splitter cables, a Daisy Chain Connection, or a Line Output Converter (LOC). This guide provides detailed insights into each approach, allowing you to choose the most suitable method for your requirements.

Method 1: Utilizing RCA Splitter Cables

To link two amplifiers through a single RCA jack, RCA splitter cables offer a practical solution.

Step 1: 

Familiarize yourself with the role of an RCA splitter cable, effectively converting one connection into two.

Step 2:

Attach a single RCA cable to your device’s output.

Step 3: 

Remove any remaining white or red male plugs if present.

Step 4: 

Connect the RCA splitter cables to the vacant spots left after removing the male connections.

Step 5: 

To connect two amplifiers, acquire two sets of white and red male plugs. This method allows the division of a single RCA jack into two and facilitates the connection of two amplifiers.

Method 2: Daisy Chain Connection through Linkage 

The Daisy Chain Connection, implemented with a Line Output Converter (LOC), enables the connection of more than two amplifiers through one RCA jack.

Step 1: 

Establish a connection between a single RCA jack and your electronic device.

Step 2: 

Keep the input and output units of the amplifiers unconnected.

Step 3:

Use a Daisy chain splitter to interlink the RCA connections.

Step 4: 

Attach a wire from the splitter to the first amplifier’s input outlet, and another wire to its output outlet. The second wire, equipped with a male plug, is linked to the subsequent amplifier.

Method 3: Employing a Line Output Converter (LOC) 

The Line Output Converter (LOC), a compact device, serves as an efficient means to split RCA signals, offering distinct advantages over alternative methods.

What is LOC: Line Output Converter

The Line Output Converter, abbreviated as LOC, is a compact device that facilitates the division of RCA signals. Functioning akin to a splitter, its usage is effortless, enabling the connection of two amplifiers seamlessly.

This method garners favor for a couple of compelling reasons:

It elevates safety standards by isolating power sources from input and output components.

It offers the versatility to link numerous amplifiers using only one RCA jack, diverging from splitters constrained to a maximum of two amplifiers.

In scenarios where the intention is to establish connections for multiple amplifiers or speakers (as observed in-car audio systems), this technique unequivocally emerges as the most optimal choice

A Line Output Converter (LOC) is a device designed to convert the signal from an audio player into a format usable by another receiver. Also referred to as a Line Output Converter, it features components such as transformers, high-voltage resistors, and a neutral point. The output end of the LOC is equipped with an RCA connector that connects to the amplifier.

Advantages of LOC

  • Segregates power from input/output units, enhancing safety.
  • Facilitates the connection of any number of amplifiers through a single RCA jack, unlike splitters limited to two amplifiers.

Using the LOC to Split RCA Jacks

  • Enhance the number of RCA jacks.
  • Connect the LOC to another output or utilize its output as an RCA connector.
  • Generate additional RCA jacks as needed.

Comparison of Methods

  • Splitters require no power and are suited for simpler setups.
  • LOC is ideal for scenarios requiring more RCA jacks and enhanced safety.

Efficient RCA Splitter for Multiple Amps

The three-way RCA splitter stands out as the most efficient option for connecting multiple amplifiers. Also known as a Y cable, it divides the signal into two distinct paths, connecting each amplifier through an additional wire. This configuration maintains balanced volume levels between both channels, ensuring an optimal audio experience.


By comprehending the various approaches to connecting multiple amplifiers through one RCA jack, you can tailor your choice to your setup’s demands. Select the method that aligns with your goals, ensuring a seamless and efficient audio amplification experience. If connecting multiple amplifiers, opt for the three-way RCA splitter for superior signal distribution. Additionally, consider the use of a Line Output Converter (LOC) for enhanced flexibility and safety.


What is an RCA Cable?

 An RCA cable, short for Radio Corporation of America, is a connector used to establish audio and video connections between electronic devices such as TVs, stereos, and monitors. It features a distinct white and red (or sometimes yellow) plug design.

How many RCA jacks can be hooked up to one amp? 

The number of RCA jacks that can be connected to one amplifier depends on the amplifier’s design and capabilities. However, connecting more than two amplifiers with RCA is not generally recommended for most receivers.

How many amps can be hooked up with an RCA cable? 

The use of a three-way splitter allows you to connect multiple amps to one RCA cable. To achieve this, it’s ideal to have a receiver or a head unit with at least one set of line outputs.

Are there different types of RCA jacks?

Yes, there are various types of RCA jacks. The most common type features a single female connection with curved metal rings on either side. There are also variations, such as a male or female connection with a shape resembling an upside-down trapezoid, catering to different needs.

What is the most efficient RCA splitter for multiple amps? 

The most efficient RCA splitter for connecting multiple amps is the three-way splitter, also known as a Y cable. This type of splitter divides the signal into two paths, maintaining balanced volume levels between both channels and ensuring optimal audio quality.
