They will work on just about any radio.
I am putting one in a AR3500 right now.
Also if you would like to see a new video of one installed in a Cobra 29 it is now up.
I got over 135 watts from this radio with nothing done but the install. After I did some tuning I have gotten 145. PEP
I would say talking wattage is around 110-125 not too bad for a Cobra 29.
Here is the Video
