Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. By using both inputs with the same mono signal doubles the subwoofer sensitivity. This means that there is now only half the signal strength to drive it to full output.
Why do subs have 2 RCA inputs?
Originally, RCA was designed for mono single-channel signals. Two separate left and right cables were introduced when stereo became available. While the receiver is responsible for converting the left and right channels into a single signal when using LFE, this happens inside the subwoofer with RCA.
Why does my subwoofer have 4 inputs?
What is this? The main reason that 4 terminals are included on some speakers, is that rather than being limited to running a single cable to each speaker, it is possible to use a separate cable for each pair of terminals.
Does a sub need left and right inputs?
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.
Does a subwoofer need both RCA cables?
The preferred method of connecting a subwoofer is through the subwoofer output (labeled SUB OUT or SUBWOOFER) of a receiver using an LFE (Low-Frequency Effects) cable. It’s usually just one cable with single RCA connectors on both ends.
Why is there a left and right input on subwoofer?
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.
What does HF and LF mean on speakers?
HF stands for high-frequency. A high-frequency (HF) speaker is also known as a tweeter. LF stands for low-frequency. A low-frequency (LF) speaker is also known as a woofer.
What is the best way to get bass out of a subwoofer?
Just follow these simple steps for great bass:
- Remove the distortion.
- Flatten the signal, open the low-pass filter.
- Adjust the subwoofer gain and low-pass filter.
- Adjust the bass boost and subsonic filter.
- Match the subwoofer level to the receiver volume.
Do I need a splitter for my 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.
What is the best powered car subwoofer?

Do subwoofers need amplifiers?
A subwoofer is, again, kind of a massive machine, and most subwoofers are going to require more power than your car can provide on its own. As such, prospective buyers are best off just accepting (from the start) the fact that they’re going to have to purchase some kind of amplifier in order to have a functioning subwoofer in their car.
What does and AMP do for subwoofers?
The amp is going to serve as a middleman or intermediary force between your car’s engine and your subwoofer. The amp is literally going to amplify the energy that your car produces, and will then feed that energy to your subwoofer, resulting (hopefully) in a whole lot of bass.
What are dual voice coil subwoofers?
Voice coils transmit an amplifier’s power signal and shift the subwoofer’s cone in and out. Subwoofers are commonly classified as single or dual voice coil subwoofers. Dual voice coil subwoofers have two voice coils inside of the sub, while the aptly named single voice coil (SVC) subs have only one voice coil.
