Okay, not crimping, but the compression type. I have these:

they go on the interior cables like a glove, but the black cable that comes from outside, the one which has the "double cable" with the coax and phone cable on it, I cannot 'crimp' for the life of me, the outer casing just bags up and the connector doesnt fully go on, iv tried heating it up with a lighter, but that just made a mess of it, iv thought of splitting the cable down the side to make it bigger, but I thought id ask on here first, there must be some techs who know what im on about
cheers
