I'm expecting delivery of my new S sometime between tommorow and the 23rd. Installation of an aftermarket alarm with proximity and motion detectors (not by me: I want someone who knows what he's doing ) is high on my list of priorities. There's an Al & Ed's Autosound right across the street from work, but I don't know anyone who's had anything done there. I'd appreciate recommendations for installers in or near westside LA or the Southbay. Heck, I'll have a car -- make that anywhere in the LA area! Thanks in advance for any suggestions.
