Fitting Autocom speakers etc to BMW enduro helmet.
If anyone is interested, I fitted it in the end and found it very easy. Just a little more involved than simply sticking the speakers in. I removed both cheek pads, partly stripped back some of the covering which is glued on and found a rather thick piece of foam inside where I wanted the speakers to be. So simply removed the foam. I did have to removed about a millimeter of styrene shell but this is only a lip which I know sounds naughty but if you see it you will understand it really is nothing and doubt it would have any affect on the strength/ safety etc. Then I used a thin piece of foam to cover the speakers and make it so the padding (speakers with my bit of foam) is about the same as it was when I started if you follow what I mean. Then re-fitted the original covering which is still very sticky and simply stuck back down as it was.
The result looks just like a standard helmet inside without any speakers etc. The only difference is the boom mike and the cable coming out of one side. I did take my time (as I always do as I'm a bit of a perfectionist) and I guess it took most of the evening. But now feel very happy with the result.
Hope this will give others a little confidence to tackle this job, it really is easy.
Chris.
