I recently had a new amp installed and I blew my speakers (my own fault). My old speakers were Hertz DCX-165s. This morning I had a new set of Hertz MPX165s installed! I can honestly say, that these are the best sounding speakers that I have ever had on the bike. In the past, I have had stock, Hog Tunes, and J&M speakers. These sound awesome and will be able to handle the power from my amp as well. They were also on sale too! Got a great deal overall!!!!!!!!
