Sub wiring.

[GWORREL]

Hello
Need help with PSW Polk 350. Have power but no sound. Only wire I see is from sub out on receiver to LFE on sub. Is this right, do I need a special wire for the sub?
thanks

Hello and welcome. No special cable, just an RCA. Are you certain that the AVR is actually sending a signal to the sub? If in doubt, refer to the AVR's owner's manual.

If you are still having issues, check for a fuse in the sub to see if it is blown.

Most AVR's have the LFE, sub, port turned off and you have to go into the settings on the AVR and turn it on.
