Installing a Cardo pack onto Helmet

[draser]

So I tried installing a Cardo system to my first helmet, which had no comms obviously. Fiddled with the speaker location for about an hour, unsuccessfully however, as the speakers seem to be too thick and the helmet feels tight (with the speakers installed) regardless where I locate them. I had to return it...

Speakers are usually a problem, for one reason or another.
I have Cardo system in my HJC RPHA 11 Pro. ANd have installed them in other helmets.

1St. the helmet must have speaker pockets.  Most helmets do now, but some models do it better than others.

2nd.  Speakers usually need to go towards the front of the pockets for good volume.

Better luck with next helmet.

What type of helmet?  I added a Cardo to my Shoei.

Oh, it's a cheap Nikko helmet, that does have speaker pockets; however, it's a tight fit to begin with. The other helmet, fits a little looser - for same size - and speakers (that came with helmet - fit fine.

Anyone install a Sena or Paktalk, etc. into an HJC CL-17 full face helmet? Been hoping to someday myself, if poss.

My Shoei is the first helmet I've owned that I didn't have to carve out speaker pockets.  All of my HJCs required careful carving to get the speakers in right, even though they had "pockets".  I had one shop install mine for me and they essentially had the right size hole saw to cut into the styrofoam.  It was definitely a cleaner install than any of my attempts so you could stop in a local dealer to see if they will install it.
