Best Line Out Converter; Creating Amazing Sound Systems

Line output converters are an essential part, especially when designing a car system with subwoofers. If you have a factory radio, a four or five-channel, you will require a line-out converter. 

This converter will help convert the output from your speaker to an RCA signal for preamps to make for better sound integration in your system. 

The output RCA signal can then be pushed into an amplifier which you will connect to your subwoofers.

Selecting a suitable amplifier and a line-out converter are two crucial factors that any system owner should consider. If you don’t know what option to go with, here are the best converters available in the market.

What Are Line Output Converters 

You could have bought new subwoofers and an amplifier, but you don’t know how you can connect them to your car’s stereo. You will need a line-out converter to help you get around this problem and enjoy your music better. 

To get you all sorted, we need to know what a line-out converter is, what they do in your system, and how to install it. Let us get into the specifics to ensure you have all the information you need;

A line-out converter converts high-level signals from your stereo to low-level signals that you can feed into an amplifier. 

This is necessary since most radios don’t have a low-level RCA output, so you cannot connect an amplifier directly to it.

Most radios have some inbuilt amp to make them work with the factory speakers. In most, you will have 4 or 6 wires coming from the radio to the speakers, with some cars having an inbuilt amplifier.

This means that you have to convert the speaker level outputs to one an amplifier can use. This will allow you to connect more subwoofers that will give better sound. Figure out how many outputs your radio has and pick the best high low converter. 

So how do line-out converters work? They have a reduction transformer; they have a difference in the number of windings from the incoming signal to the outgoing signal, like a step-down transformer with electricity.

This process steps the high speaker level output to a lower RCA signal that can go into an amp. The Signals from the stereo are amplified and can’t be used as input for an amplifier, so you need a line-out converter.

However, not all aftermarket amplifiers will require a converter. Some amps accept anything from 2 to 14 volts input; depending on your amp, you might be able to connect it directly to the speaker lines and amplify the signal.

While you might choose not to use a line-out converter, you should do it for the sake of your amp and speakers. 

If you have a high-quality converter with bass control, you will enjoy easier upgrades and better sound quality.

Most aftermarket line-out converters have a flutter frequency response, and some have a load circuit. Load circuits will be vital in a system that does not use any factory amplification.

This will prevent the speakers from popping since the factory radio or amp doesn’t see the speakers.  Having a load circuit will keep your speakers safe and performing at their best at all times.

You need to get a line-out converter that supports a full-range output. This way, you can amplify any signal with your amplifier using its internal crossovers. If you are connecting subwoofers, your only concern will be the base frequencies. 

However, if you are connecting a 4-channel amplifier, you also need the midrange and high-level frequencies. 

This requires that you have a consistent and full-range output supplying your amp to give the best results. 

A connection will get more challenging when dealing with multi-channel systems with amplifiers that go into separate tweeters and subwoofers. 

Such systems could have up to 8 channels, and you will need to join them for your connection to work.

The connection for a line output converter is relatively simple despite how complicated it sounds. 

You only need to make sure the signal goes through the converter before getting to the amp. As soon as you know what wires go into what ports, you are good to go.

Connect the speaker output from your stereo to the input on your line-out converter, then connect the output from the converter to your amp’s input. You might need to cut into the wires to connect the devices if the radio doesn’t have ports. 

Factors To Consider When Getting A Line out Converter

Getting a line-out converter is as crucial as choosing subwoofers or amplifiers for your car since it will affect how they both work. 

The market is flooded with products, and it might be challenging to select the product you need. 

With online shopping, you can order the converter online and get it in a few days. Before placing your order, here are some critical factors you should look into to make sure you are satisfied by the outcome; 

1. Number of channels in your system

Some stereos are simple and easy to work with since they are only single or dual channeled. A simple line-out converter can be used in such a situation, transferring the signal to the amp.

The problem comes when 6 or 8 channels from a factory amp separate the subwoofer signals from tweeters. In such a case, you need an audio control line out converter such as an LC7i.

Such products will support multi-channel input to make connections easier on you. Some high-end line-out converters will do summing and equalization to produce a well-balanced signal that is clean and combined for an external amplifier.

2. Your Amplifier’s Power Rating

Amplifiers have different input requirements in terms of signal and power rating. You have to account for this difference when selecting a line-out converter since getting the correct input for your input is the basic need.

For your amplifier, you need to think about the signal and power. If the line-out converter doesn’t have enough power output, it will be unable to support the amp, so you will not get as much quality and performance as you’d expect from your amplifier.

You need to get a line-out converter that matches your amp when it comes to the signal. This will ensure the output is not too low so that you reduce the risk of your speakers bottoming out when they get signals they can’t process.

A good choice would be to get a line-out converter with full-range output and calibration options. 

This will allow you to change the settings appropriately to get the converter to work well with your amplifier at different settings.

3. Type Of Converter

There are two types of line-out converters, active and passive, and you can tell the difference since active converters have power connections while passive LOCs do not. Each of these options could work for you, depending on your radio.

Most people prefer active line out converters because they have an external power source to give a stronger output signal and voltage. This means that you get a cleaner signal and better sound from your speakers.

Passive LOCs are more like adapters; they do not affect the signal other than stepping it down. This might lead to a drop in sound quality and issues with the amp bottoming out since the converter cannot control its signal.

Active line-out converters will offer you more functionalities and perks that can help you manage your sound better. 

It will give a clean signal making it easy even for low-end amps to work and produce high-quality sound.

A passive LOC will work if you have a powerful radio and advanced amp that can deal with any issues on signal quality. 

A lousy amp will only worsen the situation since it will amplify low-quality signals to give erroneous output.

4. Added Functionalities

All line-out converters can give an output, but what more can they do for you? All passive converters are disqualified when looking at added functionalities since they don’t do anything other than step down the incoming signal. 

Active converters, on the other hand, will offer you a long list of benefits. You could get a converter that has a broad spectrum of output options that you can choose from. This will allow you to use it with different amplifiers that differ in power rating. 

You need additional functionalities to balance the sound, merge the signals and clean the input to produce high-quality sound. You should have diodes to control every aspect of your setup to give you a more personalized feel.

The number of input channels offered by a converter is also essential. If your radio has six channels output, you need to get a converter that will take in all the inputs to utilize your radio’s capabilities fully.

Having many input channels will allow the line-out converter to take in all the signals for speakers and tweeters. 

The LOC will then mix up the signals to give a single output that your amplifier can efficiently work on.

5. Ease of connection and Use

This is an issue if you intend to connect the line-out converter yourself. If you don’t have any experience with electronics, it would be wise to use a converter that is easy to connect and use to ensure you don’t get stressed out trying. 

In such a case, a passive converter will be a solid choice since its connection is simple. There are ports for you to plug in the wires; the ports are labeled and marked with colors, so you know what goes where. 

When it comes to active converters, chances are, it gets more complicated depending on the functionalities it offers. If it supports many channels, then a dozen input ports might be labeled for professionals.

If you are dealing with a system you are unfamiliar with, you need to get a professional to make the connection for you. It is better to spend extra money on installation to ensure your devices are safe for future use.

The price will depend on the features, type, and size of the line-out converter. It should therefore come after you have thought of everything else you need from the converter. It is better to spend a lot of money once and get satisfied for a long time.

Cheap products tend to be of low quality, and you might get forced to replace them after a few months. 

Considering that the connections might be complex, this will be messy and expensive for you, so it is best to assess quality and performance ahead of anything else.

Conclusion

You need a line-out converter when making a connection between your car radio and an external amplifier. 

The best line out converter for subwoofer will balance the signals and make them easier for an amp to handle, so you get high-quality sound. 

There are passive converters that don’t alter the signal in any way other than stepping it down. You would be better off using an active converter that can change the signal appropriately to merge several channels and produce clean and complete output.
