This post is coming a little late but heres my rendition of a mobile PA =)
I study at Cleveland State University here in Ohio for Mechanical engineering and participate in the Society of Automotive Engineers Mini Baja competition with a bunch of my good buds. We were asked to represent the engineering department in Cleveland's St. Patrick's Day parade and I immediately saw the need for a high sensitivity mid-high box... =) any guesses so far!?

SQUAD UP!

The 2512 melded OT12 ran a wonderful selection of Dropkick, Flogging Molly, and of course James Hetfield's rendition of Whiskey in the Jar pretty nicely off a tired old motorcycle battery and the dash mounted Lepai 2020! big props the the iPhone App "EQu" for letting me make a custom curve to run my tunes through!!!
Thanks for the plans as always Bill! The party is never far from someone with a circular saw and a music library=)
