You can get a good alarm at almost any car stereo retailer. The problem is finding some one that you trust to do the install. 95% of how an alarm works relies on the install. If you want to drive your H2 over to California I could help you out,HAHAHA! Just kidding...I have found that any brand of DEI is very good and user friendly for the installer and the customer. They are concidered top of the line and can do everything from remote door locking to opening your sunroof. If you need email me and I will send you a tech sheet on where all the wires are that you need for the alarm install. Good luck! C
