Trust me, I recognize it to be a big theft target, especially when you post and share the pictures of it on line as I have done. I would say there is already a dozen or so thiefs already plotting on how to steal it with my license plates showing and stuff, so they know where I live. When doing a big audio system and installing an extra battery or 2 or 3 or more, LOL, there are many more options available to you than the standard alarm install package with a kill switch. Since you do have other power supplies, some in plain site and others hidden, you can do alternatives. But if a thief wants that stereo, not much you can do to stop it except make them play on your turf. My stereo nor my truck will be stolen at home, I can promise you that. But I can't stop a thief who wants it so bad that they would follow me around till I park it in a parking lot to do some shopping and then they could simply jack the vehicle with a wrecker and make way with it. I don't know if a cop would even notice that it is being towed with the alarms sounding. I need to check into that with HPD on what there procedure is. Then a thief would take it to an undisclosed location and start cutting wires until all of the alarms stop and then strip it down to bare metal. But that is about there only option on my vehicle. Nowadays, with so many alarms on the market and everyone having one, the sound of it makes your first instinct say, adjust the motion sensers on it. Come on buddy, get with the program, LOL. I hear alarms all the time and pay them no mind. But they won't drive away in my vehicle. Nor will they spend much time in it at my house without arising me, my family, my neighbors, or the dogs. Someone will notice it here, but not at a mall or something and then only time will be an issue. You can't simply crawl under my truck, cut some wires, and then off to the farmer's market you go, LOL. Years of experience have taught me better. Only a handful of people know everything about my truck. Me and the insurance company know everything, and then serveral different installers know a little each, and only 1 installer, the current one, knows it all. He has to, cause all of the wires are there and of course he asked about why this battery is here and why this one is there and so on and on. LOL, not to say too much, but it was mostly done "before" the major install ever begin and then some more added after the batteries were installed and the ground work began. I don't mind spending a few thousand to try and protect a few more thousand, but it has to be done. Al, if you would like to know more privately, let me know. I can help you.
