I read every bike audio post I could find (there's a lot of good info in the HD Forums ) and found where many had removed foam baffles, polyfill, etc. I had installed Boom Mats and they really created a snug fit so I decided to pull it back apart and remove them to see if there was any difference. The difference was immediately recognizable with a much fuller and deeper sound. Im not saying it sounded like I had just installed a sub, but the bass was there and the sound was much more clear. At this point I was happy they finally sounded better than the JBL coaxials I had just removed.

While doing research this past week, I located a reputable audio shop that is actually the local dealer for Hertz, Audison, and Arc Audio. While out riding today I visited and spoke with the owner about amp settings. He advised they could assist in dialing it in and use an oscilloscope to ensure they get the most out of the components. I have elected to take the bike to them Monday morning and let them get this project across the line. I can then make note of their settings for future reference.

Robert, I sincerely appreciate your guidance throughout this process as well as your continued willingness to assist. To be honest, I have partial hearing loss in one ear and a severe case of tinnitus so I probably can't even tell what good would even sound like. Too many years banging on drums and listening to loud music.
I wonder when I read about some filling and even lining or sealing up the enclosures that the speakers fit it. If anyone notices, realizing that the enclosures were designed for the OEM speakers, that the enclosures are ported. I don't know how much actual science is in to the design of these enclosures. Conventional enclosure design wisdom would tell you that the ABS plastic is not a very good material for enclosures and that any efforts to decrease resonance in this material could not be bad. However, I have also read about some sealing off these enclosures, and to me at least, it would seem to really limit the sound from any speakers. A truly sealed enclosure would surely need to be larger. JMTCW
