Heh, mine's more "store-bought" than "custom" right now, but it allows for targa storage, is easily removable, and took about 3 seconds to install. The amp was another story--I spent some time fitting it under the passenger's seat, but it's almost perfectly hidden. The system actually sounds pretty good, to me; I like bass, but I don't want people a block away to hear me coming. 10" SVC Rockford Fosgate driven by 400w Kenwood Amp...has worked flawlessly for me for the past 5 years or so.
