Pro-Tek Car Audio & Security offers professional installations at competitive prices. We do on-site installations that serves Northern and Central New Jersey, New York City, and Eastern Pennsylvania. We currently work out of a garage located in Northern, NJ and do not have a shop right now. We prefer that you come to us, but we can come to your location to do an on-site installation. It all depends on the type of installation that will be done. We also do contract work for dealerships and GPS tracking companies.
