I purchased a nice Philco console stereo and removed the old components and am installing some other vintage equipment. My question is the right and left speakers are sharing the negative and when I turn my receiver speaker control to right or left the speakers do not cut all the way out to just one side or the other. Should I separate the negative to each side and this would resolve the issue and give me a true stereo sound or is there more to this, these are some cool speakers in the cabinet and I want to use them, there are about 5 speakers on each side. woofer, tweeters and midrange. Thank you for your help.
