hey there i just bought the clifford matrix 12.5x and i was told its pretty good and very sensitive but mine even though im around the car it wont beep or nothing i touch the car hit it, shake it, and still nothing it only beeps like if i smack it reallyyy hard but anyone can scratch it and it wont even beep?!?!!? isnt it suppose to have like a proximity senser where when you get close it beeps?!? thunder wont sound my alarm off not even a damn earthquake would probably not sound unless you actually BREAK in to the car that bitch stays quite?!?!? is there like a setting with the key that you can make it stronger and very sensitive???

 

Did you adjust the shock sensor when you installed it? And no the alarm does not come with a dei 508d proxy.
