It depend on what area you live in, and what enemy's you have. A system in the country would be less to worry about than in the city. I know what you are talking about.You could turn you jeep into a speaker on wheels if you really wanted to. If I was you, I would go for the speakers that mount to your roll bars and body. VDP makes some good stuff. For the head unit, well that may just have to be. Unless you want to go for a Tuffy console.They are basically break in proof, and some have a lockable head unit area. Hope this helps. Any other questions just contact me. [email protected]
