I need to know if there is a solution to my problem. during the construction of my house I ran all of my speaker wires through the house all 14/ 2. the problem is that the wires the should go from the volume control to the receiver should had been a 14/ 4. I noticed the problem a few months later. I cannot pull the wires as all of the holes were sealed by the builder to prevent fire flash. any way to do a wireless remote?
