Updated Pictures
Based on some of the responses, I made some changes this morning. Again, thanks to everyone who commented and contributed ideas. I found a spot under the dash on the driver side for one speaker, and moved the other speaker to the "dead" space on the right. Now peoples' legs fit. New York doesn't prohibit suction cup mounts on windshields (I don't think), and the placement of my blue light and radio head really doesn't obstruct my view of the road. I can't seem to find a good spot for the head anyway. I removed the phone mount, as it was a redundant piece of equipment. My car stereo features Bluetooth with display, and GPS, so having the phone up where I can see it is now unneccessary. Here are some updated pictures, as well as a shot of the FT-7800 main unit in the trunk I forgot to post yesterday.
