Car Audio of course! My interest was first peaked when I was in a brand new PT Cruiser. I turned the stock system up as loud as it would go and I saw the mirrors shake a little. I was 13 and thought it was so freaking cool! I then went to YouTube and I think the first thing I searched for was "Audio in a car." I eventually found guys like Steve Meade, TwisterChild420, EXO, etc and they along with others I found/meet along the way thought me most everything I know about car audio! So if any of them read this, thank you!
