Hi Richy,yes I know,when Halfords fitted it the reception was terrible so I went back and he said "yeah I know,it needs an amplifier",so I asked why he hadn't fitted one,"didn't have one" says he,and you didn't think to mention it? asked I,"no".Anyway he fitted one,but through a permanent live rather than a switch live which did my old battery no good at all in the winter.It's never been any good which is a shame as its a good set and I would like it sorting out and wouldn't trust Halfords anywhere near it.
