Just a quick intro. Did a lot of car audio stuff back when I was in my early 20's, now that I have a teenager (scary) we decided to do a project together. The car is a 2007 Sonata SE, which has a pretty decent system in it already, but we want more and better sound. Doing research I found this site and have been lurking for a while and decided to register. Looks like a ton of good info here and wow has this industry changed in the past few decades!
