If you meant that the subwoofer amplifier has the power in then we need to check the amplifier.If your subwoofer speaker is ok after testing with an 1.5 volt cell then you concentrate if the amplifer has packed up., After testing for fuse, speaker connection, speaker wires. you will have to check if your power amplifier output has failed. Since you have not mentioned the make/model i am not able to pin point but you may open and test for damaged output transistors, components and replace accordingly only if you are competant. Hope I could help. Good day

Subwoofer not working


The subwoofer is dependent on a sound amp powered by an external source whereby the speakers are powered by the line output from the sound source (like a computer speaker out jack). Powered Subwoofers controlled by a power amplifier require a power source such as an AC/DC source plugged into the house power. If the device is defective or a mismatch, the subwoofer will not function. Try a new power transformer and see if that fixes the problem. Other than that, if the power transformer is good, then the woofer could be defective.

No Soound on Subwoofer from Yamaha RX-V363


I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

No sound out of subwoofer


Connection from receiver subwoofer output jack RCA plug male go into your powered subwoofer low level input with other end of cable, then you need to select Subwoofer YES/NO on the JVC receiver speaker setup menu option, select YES if this is a powered subwoofer you are using, should power up the subwoofer, may have to adjust a test tone balance for multi speaker output also, try trimming up on the subwoofer channel to initiate the signal on if the sub has an auto-on feature.
