I just bought a RF modulator that you can plug into any MP3 player, etc. It broadcasts on four different FM frequencies. I was skeptical at first, but the thing really works. I use a Nomad Jukebox and now have over 100 albums at my fingertips. Quick easy and only $29.00. I realize that the original speakers are still in, but if I changed them, I would be tempted to get new amps then new head unit, etc.
