Are my jvc sp uxj60 speakers compatible with jvc rx-888v?

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.

There is some sort of setting you need to change on the JVC receiver. I had this same problem, and I read the manual and it solved it. You need to press and hold down a button to change the mode. Your unit probably says "TV Sound" right now. Once you press this button (not sure what button) like the manual says, the display should change to "DBS" and then it should work just fne.
