WTB: Helmet Communicators - Complete or Parts

I'm wanting to put together a set of rider-rider and/or rider-
passenger communicators. I'm interested in insertable speakers, boom
mics, switching boxes, etc, that I can adapt to my purpose.

Also interested in working systems or partial systems. Let me know
what you have laying around.

Would consider pre-wired helmets if price is low.

Located in Dallas Metro area, please.

Thanks!

 

Thanks, but most of the cost of that system is in the FRS radio. I
already have plenty of FRS radios, may use them with whatever I come
up with.
