One of the senior members and chairmen/vice president at the Ontario Z Car Owners Association has his own car audio and security shop. I have heard that he does nice work, though I have never used his services. Try reaching out to him; AST (Auto Sound Technology), Mauricio Gomez 416-564-7901 or
autosoundtech@gmail.com. I met him at a recent swap meet and he seems like quite a decent guy plus he is also a Z owner. Also, if you are a member of the OZC you will receive and additional 20% discount on labor and accessories. Not a bad deal. Good luck and let us know how it goes.
