I have Hawg Wired and they are great people to deal with. Those and the stock amp did the job for me, but again as I said, my pipes are really loud. I run Rinehart trues with the performance baffles. I can hear the music and I am good with the quality all things considered and I am a music freak. Someone told me about a bass reflect that can go under your seat that gives you the sound and feel of bass reflex. I haven't heard about the tube system Boom Audio offers. I know there has been a few blogs about the install, but i can't remember anyone saying anything about the sound. It makes sense? Back to the music. I spent $360 for the speakers, I guess you can upgrade the quality of the amp which would cost another $1,000. I've seen people install the speakers in their lower fairings. I know the speakers are pointed toward the rider and I sure it sounds better, but I have not heard the system in person. Besides that as you well know, a motorcycle going 80MPH down a highway is the furthest thing from acoustically designed perfection....I don't have the thousands to spend just to have it and justify the quality? I would if I had thought it would make that big of difference other than jamming when the bike is parked. Good Luck....sounds like you got your checkbook out already. Thats what makes it fun!
