My sub install, messy and unprofessional as all hell. When you're standing next to it you can't see the wires as much though because it's sort of underneath the shelf on the back. I didn't buy a new HU for it because I'm a cheap bastard. I also had to use a converter because the amp I bought didn't have one, so I've got more wires and hence more mess than I think I would've otherwise.
Our 'new' 1995 Taurus wagon, loaded with every option but mysteriously lacking the third row of fold down seats... Like an Escort, only big. :wink:
