I did some more research on Bluetooth speakers. So far, I have been interested in some from Motorola, one from Brookstone, and a couple from Ecoxgear.
I was at a Brookstone near me this afternoon and they had a few Big Blue Go Wireless Bluetooth Speakers in stock. It looks like they are no longer making these. The website shows that they are Currently Out Of Stock. I like that this has a mounting bracket with a suction cup for windshield mount. The reviews that I have read on these are favorable.

Since I like Motorola naturally I Googled Motorola Bluetooth speakers. One of the ones that comes up in a search is the Motorola X Sol Republic Deck Ultra Wireless Bluetooth Speaker System. One of the features that I particularly like is that it has 3.5 mm jacks on it for both input AND output. So, if I understand this correctly, you could use this to received from the Unication and also "daisy chain" a wired commercial and mobile loud speaker to it.
Motorola
There are also other Motorola Bluetooth speakers available, some of which have a visor mount. I think the visor mount would be quite handy for a number of installations. One of the other Motorola Bluetooth speakers is the Motorola Roadster 2. This also has a built in FM transmitter, which might be handy for sending to a broadcast radio receiver.

Another one is the Motorola SonicRider Bluetooth In-Car Speakerphone.

The Bluetooth speakers from Ecoxgear that have a compatible suction cup mount are the Ecorox and the Ecopebble speakers. The Ecopebble is a monaural speaker. It looks rugged and is waterproof.

The Ecorox is rugged, waterproof, and has a pair of stereo speakers built into it. It might be the definitive choice if you want to mount a speaker in your Jeep and continue listening in the rain with the top down!

It looks like the 1/4-20 male that Ecoxgear uses is common to the camera industry. It should also be noted that RAM Mounts, which makes quite a bit of gear for squad car mounts, also has compatible gear for the 1/4-20 male thread.

I haven't finished researching this yet. This just happens to be what I have found so far and I hope to hear comments from others regarding compatible Bluetooth speakers suitable for mounting in a vehicle.
