I have two sets of monster cables I got from the cable company when I hooked up the DVR and HDTV. They are white component with two analog audio cables. They are 20 feet long and I only need at most 3-5 feet. They seem like they are quality cables they are just too long. Can I cut these to shorter lengths and put new RCA plugs and use them for Component, Digital audio, subwoofer. All the cables look to be the same diameter, however I have not cut them yet to see if they are the same on the inside. If I can do this what do a need ie. cutter crimper what types of plugs. And where would be the best place to purchase them.
