1. I had the unit mounted under the driver's seat and had an auxiliary speaker mounted to the roll bar near my ear. A friend set it up for me and set the head unit on top of the windshield near the loose that you use to tie down the windshield when you put it down on the hood.
2. What sucks is when the TJ got stolen, I had the head unit and mike on my kitchen table which is useless. Had I lost the head unit instead of the radio, that could have been replaced
3. I am going to get the same unit for my JKU. I'm not a steady HAM user so no need to buy anything past that. I loved being able to take the head unit indoors with me. Solid dual band radio, you can easily program channels that you use on the regular. I used this radio on the Rubicon Trail and local runs.
