I have never really worried about a nice radio for my TJ until my wife pulls up in our new JK Rubicon with the gozillion speakers in it. I think it sounds great and I am wanting to do something like that in my TJ. Any radio heads on here that can give me some tips without killing my wallet? I have an Alpine head unit and a Kenwood amp lying around. The amp is like 400/500 watts or something. Is an 8 inch sub worth buying? Dont want to fil it up too much cause I run without the top alot
