I got a LG ht33s subwoofer to my denon avr1513. Connected with RCA cable but no sound.
I connected my subwoofer to my amplifier, but there is nothing. There are several connection possibilities for example RCA (L, R, Video), system connector (like monitor connector on PC), and a common speaker connection (L, R), and of course a electricity plug. No ON switch or anything else. Is that sub compatible with my amplifier?
Thanks Tizso

Make sure the wattage of the amplifier has the same amount or more wattage to the subwoofer otherwise it will not be able to produce sound because of power complications

In order to ensure output to your subwoofer: make sure the subwoofer is connected to the subwoofer out of your amplifier and make sure that your amplifier/receiver is set to output multi channel sound
The symptom sounds like an open signal shield somewhere and the cable is acting like an antenna for airborne electrical noise.
Disconnect the RCA cable at the sub. Is it still humming? NO? Problem is external to it. YES? Internal. Broken ground somewhere.
Recheck all connections making sure to twist the RCA head as you install it so oxides will be worn off.
Consider what may have changed in the environment regarding electrical devices, motors, magnetic sources. Ensure signal and speaker wires as ar not running are as non-parallel to any power cords as practicable.
Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.
1. How to Connect a Subwoofer to the Subwoofer Output
The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.
2. How to Connect a Subwoofer to Speaker Level Outputs Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.
Take a clue from the bare wire speaker connections on a speaker not matching RCA connectors. RCA is not for feeding +/- speaker terminals on REAL audio equipment.
The Denon requires an active (self-amplified) subwoofer which it feeds a specialized Low Frequency Line Level Pre Out signal.

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.
Things You'll Need:
Home theater receiver Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores. 2 RCA subwoofer cables 2 subwoofers
Instructions
Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.
Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..
Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.
Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.
Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.
Tips & Warnings
Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.
Disconnect the subwoofers from the power supply while making the audio connections.
turn down music open sub box and put another speaker at wire and check again if work means sub is ok if not check the signal cable, and put there the speaker to try signal
Speaker connections from the Denon are typically through speaker cables (glorified lamp cord).
The Denon is not capable of driving the sub directly. The powered (?) subwoofer in your setup would presumably require an RCA cable (whatever length reaches) to feed its amplifier a bass signal from the Denon's Subwoofer Out.
