Getting ready to start a small audio build. Have never done an audio build in a pick up, so that's why I'm asking. Going to go with a Fox Box. Can't decide if I should go with 1) 12" sub or 2) 10" subs? Amp for sub will be between 500-750 Rms. Either going with a JL 750/1 or Apline 5 channel which will be 500 RMS to the sub channel. Listen to all types of music, mostly rap but will jam to some hard rock as well.
