I own a Chrysler Crossfire 2005 SRT model I talked to a gentleman bill and was sold on a complete JL audio system and viper alarm system with GPS the car had approximately 6,000 miles on it I rarely drive it. everything was great for a while.that was until I kept having my car towed to dayton andrew dodge Chrysler Jeep on Gulf to Bay for electrical issues and of course by that time these guys were out of businessbasically in a nutshell I have receipts adding up to over $3000 from dayton andrew dodge and these are computer related issues from the alarm and whatever else back feeding the highly sensitive electronics I had no idea there are the experts not me I basically spent over $7000 to have my car destroyed.and to add insult to injury everything that was taken apart during the install is falling apart including the enclosure in the back.which I guess was mainly held together by liquid nailI got my ride all fixed up she now has just under 8500 miles on it and things are getting back to normal moral to the whole story is if it ain't broke don't fix it or research itaccording to the people at Viper alarms the model unit that was installed should have never been installed.
