How do you hook up a subwoofer with RCA cables?

Connect Using Stereo RCA or Speaker Level Outputs If the subwoofer’s LINE IN uses RCA cables and the subwoofer out on the receiver/amplifier also uses RCA, plug it in using an RCA cable. If the cable is split on one end (a y-cable for both right and left channels), plug it in the R and L ports on the subwoofer.

Does positive and negative matter on subwoofer?

If both speakers are wired the same, whether in the correct polarity or reversed polarity, there will be virtually no effect. Even the speakers in subwoofer arrays, which sometimes contain speakers with inverted polarity to achieve better directionality, are usually wired with correct polarity.

Do I need both RCA cable for subwoofer?

In order to hook up a powered subwoofer properly, an RCA “splitter” cable (“Y” cable) is not needed. Any single, standard RCA or subwoofer cable should do just fine.

How do I connect my subwoofer to left and right input?

To connect a subwoofer to its receiver, you can use an LFE input cable or an RCA line-in cable (used for left and right input options). Assuming your subwoofer has the option to use an LFE input, this will be your best choice. But, if not, then an RCA input option will work.

Does a subwoofer need left and right input?

Most subwoofers have both a left & right input. It usually doesn’t matter which one you use. If you are using more than one subwoofer, you can run the same kind of cable from the subwoofer’s “line out” or “low level out” to the next subwoofer.

What happens if a speaker is wired backwards?

When speaker wires are wired backward, this creates what is known as inverted polarity, which is also sometimes called “reverse polarity”. This causes the speaker to move outwardly when it should be moving inwardly, and vice versa.

Which speaker wire has the white stripe?

Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end.

Why does a subwoofer have a left and right input?

The left and right channels are combined in an LFE cable to allow for a singular cable to evenly disperse the signals to the subwoofer. Rather than having to sort through various cords and cables, you can use an LFE input as a single cable to connect your subwoofer to its receiver.
