I'm looking at getting some Rockford Fosgate speakers in my ride, I'm just wondering whats the best thing that I can get (4 door speakers, subwoofer and amplifier) for a reasonable price. I am a huge fan of bass so a subwoofer is what I would like the most. Although in order too keep up with the bass I will need some good loudspeakers. Anyone that has suggestions on a good speaker, please let me know the model and price.
