Yea baby!
Just bought an empty stealthbox on e-bay for $10.50. ($30 to the door!)
It's the first generation Vantage model made specifically for the Mk3. It's hard plastic (instead of the new fiberglass), and not carpeted (I''ll probably do that myself), so I'm not sure on what the final result will sound like, but I'll be happy to free up the trunk space.
It'll probably be another $500 for a new 10" W6v2 and a Jl amp to run it and the fronts..
And just as I was starting to enjoy my set up.. maybe I'll wait for other mods first...hmm
