You really need to listen to a few of these systems on someone elses vehicle in order to make the best decision for you. Obviously you get a lot more than just sond from a quality system like CORSA. You drive a quality vehicle...so don't go cheap on anything you add. I did go to the
www.realwheelsacc.com site to listen to the CORSA, and it sounds just like the one on my truck (very accurate), but I dont remember if they also had sounds of other systems on their site. Best of luck!
