Yes but if joe schmoe is doing it out of his garage for alot less money and has more experience than the guys at sound advice since is day job is at a car dealership and does like 15 to 30 alarms a day. Besides why are you bashing me im just tryin to help someone save money. You can go spend 1500 bucks in an alarm for all i care I just know i have the same if not better product for only 800.
