None really, now that I'm older I do not spend that much time in my car. However when I was a younger person (teens thru early 30's) I was all about it. In the early 90's I had a Rockford Fosgate Punch 75 under 1 seat and a Punch 150 under the other. Kicker super 2 in the hatchback of my 944 Porsche.Also, I had ADS plates in the doors. With an Alpine pull out CD! Those were the days !! WOW! That car Rocked!
