I have a cvo street glide 2011 and I put in the rockford fosgate 300x4 and hertz speakers in the lower fairing upper fairing also. I am not impressed with it over the stock system. I was in Milwaukee this fall for the 110 anniversary. I was told to talk with Pete from Soundz Customs. He had a booth there and I was able to meet up with him. I was recommended to him by several members on this site. Mainly tif as he also has the same bike .
Upon meeting with Pete he demo d a few different configurations for me and wow what a difference in his system. He has it so it is all plug and play no cutting of the harness. His system is not cheap , but you get what you pay for. This is why I am saving up right now to order the system shortly so I have it for spring. I have listened to others and been fooled when the bike is sitting still. It seems that at hyw. speeds is when it is more evident. There were brand new 2014 bikes there getting systems installed. He really knows his stuff and is super at taking the time to explain everything about the system.
Just my two cents as I have already spent money that did not work out.
