hey, guys am new here and look for maybe some input, I am using winisd and (to me) everything looks alright, but im wondering if I am missing anything that could possibly be harmful? I like all music but rap is what I play most. I love lows and cant get enough but love spl also. what do you guys think of this graph which would be best for rap. The box that is tuned to 30hz does not hit -3bd until 27hz is this too low for most rap. this box is going into a dodge intrepid which will have to be built in the car. if you need any more info or pictures let me know im using a Rockford fosgate 1200d to power them. does anyone know what the cabin gain might be I know all cars are different but what might I expect.
