Lately i've been seeing this kid at my work on the security camera walking up to my truck and looking in the windows. (like face pressing against the glass). He's a known thief so i know he's probably looking to steal my amps. I have a Viper 5704 alarm installed but you have to literally pound on the windows before it even chirps. So i took all the amps out and ordered the 508D Proximity sensor but cant figure out where to mount it. I read some people mount them on the headliner, and then some under the center console. Where would be the best spot to mount it at on my S10?
