You can use the following:
Connection with the LFE Subwoofer Output
If you check the Subwoofer box, you will see a place labeled “SUB OUT” or “SUBWOOFER” which allows you to connect the car stereo using the LFE (Low-frequency effects) found in most of them.
This LFE port is specially made for subwoofers only. For this, what you need to do is to connect the LFE jack in the receiver to the Line in or In Jack available in the box of the subwoofer. With this, you will easily find the location as it is usually one RCA connector in both ends.
Connection with Speaker Level or Stereo RCA Output
If the car stereo does not have an LFE subwoofer output or you notice that your subwoofer doesn’t have the LFE input, you need to check if it has the Right and Left stereo connectors.
Optionally, it could have clips that are made of springs that will be at the other end of available speakers. Observe closely if the Line In uses cables for RCA and the subwoofer is using the same. If both are using the same RCA then you will need to plug-in R or L in the box of the subwoofer.
If the cable has an end which is split with both the L and R, then you will have to use the car stereo output to hook it up. When you are doing this, ensure that both are plugged in.
If the subwoofer makes use of spring clips in the connection of the speaker wire, then there’s a need to use the car stereo output to hook it up. Mind the channels when you are doing this.
If the subwoofer has two spring clips used for In and Out, then you will have to connect either of the speakers to the subwoofer which passes audio signals to the car stereo when connected.
However, if there is just one set of spring clips in the subwoofer box, you will have to share the same receiver connection with the speaker.
