So I have absolutely no idea how to install a head unit. I got a buddy that's gonna attempt it for me. I have a 2006 charger rt. I know I need to purchase a new bezel that will fit. I was told I was also gonna have to buy a certain type of wiring harness. My buddy said even then I would probably lose my tweeters. So my issue is.. what kind of wiring harness do I need to buy and also is there a way to hook it up where I do not comprise sound quality? Thanks for the help.
