what and where to get car audio

Audibahn is GARBAGE. You are paying for looks. And in your case buy a pre-built box. I can build a box that sounds ten times better than any pre-built, but that is only when you are actually building a system worth listening to. Sounds like you want something cheap and efficient. I can give you a hand installing it, if you need a hand and are local. i installed the systems in many cars, including all of mine, and you don’t try to install a system in a $60K+ car unless you know what you are doing. Are you going with a Stock or Aftermarket head unit?
