Do you want to eliminate those bulky RCA jacks for your car audio system without any other method? Here are some ways to make Amplifier work without them.

How to Hook Up An Amp Without RCA Jacks? You can hook up an amp of your car without RCA jacks in 3 ways; by using RCA adapter, high-level inputs and a line output converter (LOC). We have explained these methods deeply.

But first, let’s learn a little about the components and essential things you must remember before setting up your home theater or amping up your car.


With speakers, you can take your entertainment to another level. This is why they are often found in vehicles and bedrooms, where there is little distraction.

While watching a movie, it’s nice to hear the film without turning up the volume on the television or the radio. By using a stereo system, the experience becomes more complete.

In this world of ever-increasing connectivity, audio systems are no longer just for music. They’re also essential to many other tasks, like Skype, web conferencing, and multimedia presentations.


Amp devices play an essential role in acoustics and boost the signal from a receiver, subwoofers, or headphone system.

They are used in several ways, including providing a louder chime for a listener to hear over background noise, adjusting the level of a signal so that it can be heard over a noisy crowd, and raising the signal to compensate for the distance between a subwoofer and the device being amplified.

Here are a few objectives you must keep in mind while dealing with amp devices:

  • Determining the Compatibility of Amp

To be compatible with other power amp devices, the produced power should be consistent with that of the other amp devices.

The compatibility of power for subwoofers should be determined by measuring its resultant force at its maximum yield (the rating), comparing this to the consequent power of the amp device it is designed to drive, and then calculating its percent produced power increase/decrease.

One of the best ways to avoid compatibility problems is to check the product manual or the manufacturer’s website for compatibility notes or troubleshooting information.

  • Placement of Amp in the Car

There are two significant points to keep in mind here. First, the subwoofers should be installed in the lowest-possible place. A dash speaker system is often a good choice if there is a dashboard.

The amp device should be no higher than 12 inches above the bottom of the dash to avoid interference with the radio and no lower than 4 inches from the floor to avoid interference with the radio controls.

Second, the subwoofers should be located far enough from the audio system to avoid acoustic interference between the two devices. The regulation of the thumb is to place the stereo set and the woofer at least 30 cm (1 foot) apart.

Electrica RCA connector is a special connector used for transmitting audio signals. What if you had an audial recording device on hand? While it’s simple enough to plug in a mic, why do you need a particular auricular junction called an RCA jack?

It’s used to unify your microphone to your hearing card on your computer. Why is it essential to use a specific audible junction?

If you want to talk into a microphone, you’ll need a proper aural channel—and that’s what the RCA jack provides. These mergers allow the audio signal to be fed into the speaker system using a wire from the amp device.

Don’t worry if you don’t want to use the RCA jack as it; we got you covered.


You can enjoy the speakers without a length setup or any need for wiring using the following:


An RCA adapter (called an RCA splitter) is used to split an audio signal into two components: one audio component containing the speaker’s audio frequency range and the second component comprising the remaining frequencies.

The first component is passed through the amp device to the speaker while the second component is left alone. Once the first component is linked to the speaker, the second component of the original audio signal is passed back through the amp device and then to the speaker.

This method allows you to connect the amp device to the speaker without using an RCA plug, making the junction more confident.


An amp device should be connected to a speaker using a high-level input (HLI). This is the preferred way of connecting an amplifier to a speaker.

Using an HLI provides a secure connection between the amplifier and the speaker. It’s easy to use, and if you’re working with an older piece of equipment, an HLI may be all you have.


Line output converters are used in audio recording applications to convert line level (XLR) signals into an audio source compatible with a CD or tape player.

They also drive high impedance headphones that may not have a built-in headphone jack. This will be required if you want to play music through your car stereo or computer speakers instead of headphones.

LOCs are very common these days. They are so popular because they convert the analog signals from the input jacks to digital form. So the audio quality that comes out of the speakers is better than with a digital connection.


There are many ways to connect a speaker to an amplifier. The simplest is to use a RCA type connector. Connect the black or white wires on the end of the speaker (usually marked “+” or “-”) to the black or white terminals of the amplifier.

Then connect the red wire of the speaker to the positive terminal of the amplifier. There is another common type of speaker connection called “balanced”. A balanced connection uses two wires, a hot wire and a ground wire. The ground wire is connected to the chassis or ground of the amplifier.

The hot wire connects to the positive terminal of the amplifier. This type of connection is generally preferred because it doesn’t interfere with other audio equipment. For example, if you are using a cassette deck, a CD player or a turntable, a balanced connection won’t affect them.


After you have successfully connected your amplifier to the speaker, you should test it to see if it is working or not. The basics are easy. You can use testing to ensure that your amplifier delivers the sound quality you expect.

Follow these steps to test the amplifier:

  1. Start with volume control.
  2. Adjust until the speaker’s sound is at peak volume.
  3. Reduce the volume to below peak level.
  4. Turn up the gain until you hear distortion.
  5. If you hear distortion, turn down the volume.

Most speakers can take only about 75% of their rated power without distortion. Any lower than that, and the sound will begin to distort.

For example, if you have a subwoofer placed at 500 watts RMS and are only getting 300 watts RMS into the speaker, you need to replace the speaker.

  1. Can you hook up an amp without RCA cables?

It’s possible to hook up your amp without RCA cables. The best way is to buy an adapter that goes between the headphone jack on your CD player and your line-in jack on your stereo.

This will allow you to use the line-in jack on your stereo and have it output to the headphone jack on your CD player.

  1. Can I use speaker wire instead of RCA?

Sure, why not? But you will need a special transformer to match the impedance of the speaker. If you are using an amplifier or receiver that has an output transformer, that transformer will take care of the impedance matching for you.

  1. Can you put RCA jacks on speaker wire?

If you want to use a RCA jack, you can put one directly on the speaker wire. This is not recommended because a lot of people do this to their speakers, and it will eventually destroy the jack or speaker.

Instead, you should remove the outer casing and use a pair of RCA male-to-RCA female jumper cables

  1. How do I convert speaker wire to RCA?

The answer is simple and easy. You need to use a splitter. This is the only way to accomplish this task. If you’re not sure what a splitter is, it basically connects 2 wires and gives a clean path for both of them. Splitting a wire into two separate ones can be done with an electrical wire cutter.

  1. Do you need RCA cables on an amp?

Yes, you need RCA cables to your amp for the antenna plug to work properly. Also, the speaker plug on a car amplifier is RCA so they need that too. You can always get an adapter or use a stereo speaker with RCA plugs on them.

  1. How to hook up RCA adapter to stock radio?

Take off the radio, and use a pair of scissors to cut through the 2 wires that hold it on. Now you can use the 2 clips on the adapter to attach it to the stock radio.

Once you have attached it, you can turn on your amplifier and connect the speaker wire to the positive and negative posts. You can also use this adapter if you want to switch your amplifier to another style.

You may also like to know that this adapter can be used for any kind of audio input.


If you’re looking for how to hook up an amplifier without RCA jacks, you’re in luck—these days, there’s no need to use the bulky, outdated jack connectors to connect your equipment to your TV or stereo.

The best way to hook up an amplifier to a device that doesn’t have an RCA jack is to go wireless. You can choose from different connection methods, including HDMI, USB, Ethernet, and optical, or use an RCA converter.
