These are very easy to fit, but the cable holes are so tiny, only a poor grade cable can be used to fit the plugs. I tried thinning out a better cable, but my little Sharp amp wouldn't handle it, so I'll have to see if I can get something a little better than the cable I'm using now, or get the amp upgraded to a better spec. Meanwhile, I have been able to get my lovely little Sharp unit playing reasonably well.
