more like a cheap alarm system for people with honda civics and expensive subs lol.
id rather go with a traditional alarm any day, but its nice to have in the mean time while you are waiting to save up. all ya gotta do is unplug the sensor it looks like. or cut the wire on the siren.
its not an alarm though it just stops people from stealing your car it wont save your subs. I have an alarm but atleast this will stop someone form stealing my whole truck.
...what they dont tell you is that it won't work on cars with switched 12v outlets. At least, based on my own speculation. If your 12v outlet is switched on and off with the ignition, the sensor wont work, right?
Thats pretty simple . . .its like a fake alarm. Good luck. Tell us how it went with it. i kind of like it cuz its like a motion sensor , but i wouldnt personally get it.
