Speaker powers on but doesnt make sound, when cranked it makes a "warbling" sound. the 1st one did it about a month ago, and the remaining one just did it today

SOURCE: virtual surround sound --only one

Hi bleewilke

I am afraid that you may need to do the same again. If they are getting broken at the plug end, you may be able to replace the plug, but modern cables need to be clamped in a moulded plug to retain any strength, a repair like this will probably fail also. Replacement is generally the best option. are they still under warranty

I am assuming you are using the standard sonamp 260 not a 260x3
and that when you say you are getting sound on only 1 pair that means only on 1 side (left or right channel only?)

Are using a speaker selector box? you must to regulate the resistance (ohms)

if so first unhook all but on pair of speakers and see if both channels are working.

if they do your problem is in the speaker selector not the amp if no then check to see what the amp level is set to. These are the two small holes on the front right of amp make sure they are set about equal at around half way up.

If that doesn't work flip the RCA cables coming to the amp perhaps you have a bad cable if that doesn't work make sure your receiver (source) is outputing a stereo signal to begin with.

lastly 8 sets of speakers off 1 amp? that's pushing it.even with a high quality Niles or speakercraft selector that controls the resistance going to an amp I wouldn't go past 5 sets.

The right way to do it would be to use 260x3 or a sonance or speakercraft 12 channel amp.
