No sound coming out of sub woffer

Yes providing it is the same impedance . EX if it is 8 ohm then they all have to be 8 ohms. Same goes for 4 ohm, 16 ohm etc.

No problem....just plug the subwoofer into your Green Port on the computer sound section. The Right and Left channel will merge into a monaural sound and come out of the speaker as if you were listening to music from a radio.

AVR-E400 has an RCA subwoofer output. This is a line level signal that must be connected to an ACTIVE subwoffer (has its own power amplifier) Also the source must contain subwoffer signal (5.1, 7.1, 9.1 surround sound etc) You will not get subwoffer signal from a stereo source such as audio CD, non-dolby type TV etc. Cheers, Don.

i have hts 3455/98 i connect perfectly all cables but sound is coming from only one speaker. pl help me about this problem.

What is the brand name and model number of your amp and sub?

set the front speaker to small or if still set in large,set the subwoofer setting to lfe+main.

YOU SYSTEM HAS TO BE DESIGNED FOR A SUBWOFFER, SHOULD HAVE A CONNECTION IN THE BACK RCA JACK THAT STATES SUB WOFFER

Could be Faulty RCA wires (they bring the sound from the radio to the amp) or a bad ground (the larger black wire coming out of the amp) This is under warrranty and you should not have to worry about it... bring it back, they make fix..

Don't bother with a repair dude it is not a cost efficient solution for you. Buy another and be more care full with you preamp or source volume going in iam surprised it isnt the sub amp that is fried.
