As per the instruction manual the overload is there because of high volume condidtions and your over heating the unit. They recomend to turn down the volume shut off the reciver wait a few minutes and turn back on the unit with lower volumes. Second it states that the peaker wires or speakers could be shorted so make sure the speakers are good and the wires when you connected them to the reciver are not shorted. If all is hooked up properly then you have a problem in the output stage of the amp and its gonna need service unless you know how to replace the defective output devices? If not Go online at the addy I give you to find about service parts or service manuals.. Good Luck http://www.jvcservice.com
SOURCE: speaker wire for subwoofer
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.
