TBH, Im not feeling it. I can admire the work that went into it, but even ignoring the obvious functionality questions of the vehicle with all that weight in it, it just looks like some kind of giant after thought. Looks like they just crammed as big of a box in the thing as they could, then stuck speakers every which way they could. I prefer an install that has a 'flow' to it, this setup lacks that almost completely.
And, Rhino's aren't exactly overpowered to begin with. I could see this thing being used as an attention getter at a car show where its just parked, but other than that, it seems to have really diminished the whole purpose of the vehicle.
