It shows you how to connect a subwoofer to an old amplifier.
Before we talk about how to connect a subwoofer to an old amplifier, let’s talk about some things you need to think about. When we connect old amplifiers to speakers or sound systems, we have to think outside the box to get them to work.
There will also be different inputs and controls on the back of your subwoofer based on the brand and model you have. The back of your subwoofer will usually have a power outlet, an on/off switch, and an RCA input port. There will also be two pairs of jacks and a subwoofer crossover adjustment and a subwoofer level adjustment there.
These are usually marked, but if they aren’t, you can find out what they are by looking at the user manual for your subwoofer or looking up the make and model of your subwoofer on the web.
Understanding your subwoofer and its ports will make this task easier, so be sure to get to know them before you start! It’s also a good idea to check your user manual to see if it gives advice on how to connect your subwoofer to older devices. They don’t always, but it’s worth going over the text just in case.
When we’re done with basic things like this, let’s look at how you can connect your subwoofer to an old amplifier. Remember that the method you should use will depend on the subwoofer you have and the ports and inputs it has, so keep that in mind.
With RCA inputs, you can connect.
Use a line level converter to connect your subwoofer to an amplifier if your sub has 1 or 2 RCA inputs but no speaker level inputs.
These converters are small devices that connect to the speaker outputs of an amplifier and convert the high voltage signal to a low level or line level. They do this by reducing the voltage. An amplifier or subwoofer with RCA jacks can then be hooked up to the outputs of the speaker, which are RCA plugs.
They’re also pretty cheap, and you can find them in most stores and online. If you can afford it, go with a high-end converter to make sure you get clear audio when you record.
Make sure you connect the wires marked with different colors and stripes, just like you would connect the wires to regular speakers. Then, you connect your powered subwoofer to RCA cables with the help of these wires. It really is that easy!
Make sure you get the right adapter for your subwoofer. If it only has one RCA input, you might want to buy one of these Y RCA adapters to combine both receiver channels on the other side into one mono RCA plug. There are a lot of tutorials and diagrams on the internet that can help you if you have any trouble.
connecting a subwoofer to speakers with low-level outputs
Next, we’ll show you how to connect your subwoofer to your old amplifier with speaker-level inputs. This is the easiest way to do it. As long as you connect the speaker outputs with a speaker wire, you can connect them to the subwoofer’s inputs that match them. This way, you can also use the amplifier or receiver to power speakers while you do it.
Because the subwoofer has its own electronics, it can scale down the speaker singles to a lower line-level signal that it can use to power itself. This method will give you good sound that you can now enjoy through your old amplifier!
Connecting a passive subwoofer to a TV
If you have a passive or non-powered subwoofer, you’ll need to use a different way to connect it to an old amplifier to get the best sound.
If you choose a low pass crossover, you can connect your amplifier to your subwoofer. In this way, you can connect the two to filter out sounds above the crossover frequency and get that nice bass sound that you want!
Crossovers come in single (one speaker) and dual (two speakers) models, depending on the brand and supplier. They come in single and dual models. You need to choose your carefully, making sure that it fits the sub’s impedance (Ohms rating).
For example, if you have a subwoofer with an 8-ohm load, you’ll need a crossover for 8-ohm speakers to get the best sound from it. If you don’t, you won’t get the right sound.
It’s best to choose one with a low pass frequency close to 100Hz too. Be sure to take your time and do as much research as you can when you look for one of these. Usually, you can find them on the internet or at a store that sells speaker parts and parts.
Once you have your crossover, you connect it to the subwoofer and the speaker, and you’re ready to go right away! If you run into problems, there are a lot of tutorials online that can help you through the process. It should be a simple task.
The last word
Just like that, we have reached the end of our subwoofer journey this afternoon! The way you connect your subwoofer to your old amplifier will depend on what kind and model you have.
Make sure you know how your subwoofer’s ports work, and don’t be afraid to ask for help if you need it!
