P.S. Digi-cam bit the dust at a friend's birthday party, so no install pics. I just followed various threads to help me out. I placed the Basslink in the trunk on the left side, up close to the seat with the front of it facing the right side. I ran the power wire through the hood release gommet and ran it down the left side of the car to the trunk. The speaker level splices came from behind the head unit, with the wires running from there to behind the glovebox, then down the right side of the car, behind/under the rear seat to the left side of the trunk. I drilled a ground wire in the trunk area, under the left panel just out of sight near the forward-most clip-thing.
I haven't mounted the Basslink permanently yet, but it seems stable so far. I don't trust this last statement, so I think some hefty Velcro under the feet would be more than enough to keep it from flying away. I might drill a hole and screw it down, but i don't feel that it's necessary at this point.
