Subs not working

[Cakesbaby]

Hi everyone

Been like it for a while but as with most things only getting around to resolve it now. Seems my subs in the rear are not working at all, no sound, nothing. Fronts, Centre and Rears are all working. Have a spare amp which I know is good and swapped them over but the problem persists.

Any help from anyone would be great.

Cheers

Strange..

All the power outputs on the 676 amp come out of one amp unit on one connector..

Seems unusual to have two amps with the same fault..similarly the wiring to the subs is straightforward..there's not enough go in the amp to blow them..

No obvious ideas..
