I have 2 15" 500Watt Pa speakers I use. If I need both of them, I currently put them back to back and face out to different areas. But I would like to be able to move them further apart to be able to play music and what not at lower volumes but still be heard through the venue.

So that being said, I am trying to find a wireless transmitter/ receiver that I can come next the transmitter to the output of one speaker and the receiver to the input of the other. I have done this with a 25 foot cable and it worked great, but sometimes I can't be running cords through restaurants.

My question is, would a wireless system for a guitar/ bass work? I can find them on Amazon, but they usually recommend only using for instruments with pickups.

I am also going to post in some other areas, but I thought maybe someone here would know.
