I run a similar unit, and have it mounted under the seat, where the tools and owners manual go.
Mine came with a 'remote switch', that is mounted to a patch of velcro, on my tank bib. Allows me to turn the amp on and off, with the unit located where it is.
I use mine to power my XM MyFi, and pump it through the speakers on the Hoppe fairing and the trunk speakers (when it's on the bike). Also have speakers in my Fulmer Modular helmet, for use in poor (full face helmet) weather. Came in handy this past weekend

I can give you more information, if you are interested. Email, or PM me, and we can talk.
