Your Polk Audio subwoofer is a passive sub and your JVC mono output is for connection to a powered sub. If the JVC does not have an amplified output for a passive sub, you'll either need to get an amplified sub, a different receiver, or buy a dedicated mono subwoofer amplifier.
Is this a NEW problem or has it always been like this? What modes or sources are affected? Generally, crackling, scratchty sound is either overdrive distortion, speakers being pushed too hard, or blown speakers.
What is the exact model. Can't find the manual for "517v".
you will need a line-level converter to use this subwoofer- it is a rectangular-shaped box with wires coming out on one end and red-and-white RCA plugs one the other. The end with the wires coming out will hook to the receiver, and the other end will need to plug into the sub.
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.
Usually, a subwoofer will have its own built-in power amplifier. Thus, it will be designed to plug into a standard RCA jack (the type used for DVD players, etc). rather than having wires to connect to a speaker terminal block. Look for a jack on the back of the receiver called "Subwoofer", or simply "SW". If your subwoofer has 2 single wires, it WON'T work with your reveiver's subwoofer output, as this output only carries a line-level signal and is not amplified. You would need a separate power amplifier for this type of SW. If your SW speaker has a DVD-type plug, it should work fine with the receiver's SW output jack.
