Where are you guys mounting your arc audio amp in the ultra? the CB makes for a bit more difficult install, so it wont mount on top of the radio so easily.
I just finished installing my ARC Audio amp inside the fairing of my 07 Ultra. It is a very tight fit but it will work. What I ended up doing was putting the amp on top of the radio. Then to get the cb to fit, I broke off the tab used to mount it to the radio and turned it 90 degrees, the antenna wire is just long enough to do this. It is a very tight fit but it will work.
I took my CD radio, and put the amp on top of the radio. I never used the CB, don't plan on using it; but if there is a need in the future, I'll figure out some place to tie wrap it up inside the fairing.
I tried to do this with a cb and component speakers, but could not for the life of me figure out a way to do it. I use the cb when traveling with other riders and don't want to loose that ability. i have crossovers residing on top of the radio and next to cb also . no room for the amp as of yet.
