The Rockford system was a new 400 watt 4 channel amp and speakers in the batwing fairing, all this is plug and play, plus you get the cables to do lower fairing speakers if you want. The amplifier is a TM400X4AD, and speakers are TMS65

Well yesterday I had the chance to try it out and the difference from the Harley stuff is mind blowing. At 140km/hr ( closed road of course ) the music is still crystal clear and at 3/4 volume, where as the Harley stuff would have not been heard even at full volume. The sound system cost $1300, and $220 install, which I dont think it was too bad. There was a lot of research done and been able to find an installer in my town was a bonus. The Yanks certainly know there stuff when it comes to sound systems. I asked if my installer if he was able to get the new system and was able to so that was also a bonus. If you have any questions feel free to ask
