I got my system hooked up at Stereos R Us near Montclair. Theyre about a mile away from the Montclar mall. I got everything (minus a head unit) installed for under $500. A decent head unit will probably set you back another 1-200 bucks. I think they are a great place. They did my alarm and whistle too. If you wanna call them I'll hook you up with their number and the people you wanna talk to.
