Welcome home Dude,
I put a shark amp and speakers on my ol ladies softail, 100 watt sounds about as good as any of the other handlebar mounts and only runs about a 100 bucks. loud enough to be heard at highway speeds. I mounted the whole thing speakers and all to her windshield except for the wired remote which I put on her left handlebar on a ipod mount.
it has a usb port, a 1/8 inch input and a sd card slot. also has a fm radio that Im sure would pick up a powerful station if you wer parked under the antenna. otherwise nada. she's a happy camper with it. I loaded a usb, a sd and she has her ipod, she can swith between the 3 with the wired remote. Not concert quality sound but at 60 on the highway following her on my ultra I can just barely hear a note here and there. guess its loud enough
