Removing protective shielding of speaker cables

I don't know if it would do any harm if I were to remove the shielding material of my Harmonic Tech Pro9 cable. The reason is that the calbes are now 8ft length and I don't need that much length. I plan to cut them out in smaller peices to replace the internal wiring of my speakers.
I don't know what to tell you about your shielding - except you might pick up RF interference if you strip your cables.

I replaced the wiring in my vintage speakers with shorter pieces of my speaker cable. A great improvement!

You can't hook up the thin tweeter wires with pieces of cable though. It's much too heavy!
