I stole all this from various sites
Hey guys...after our current member's incident, I read up upon theft prevention for car audio.
A lot of this stuff I get from other sites, some seems pretty useful, so read on if interested.
*Use common sense, don't blast your music where you live, it makes it much easier for people to follow you home.
*Don't advertise what's in your car. (already I broke these first two rules)
*Tints help prevent people from seeing what's in your car.
*When going out or to any place out of town, turn down your system a mile or two before you get there to prevent people from hearing it, then following you home and jacking it. (what happened to me)
*Install an alarm, but don't stop there.
*Modify the alarm to add horns if you can, more speakers and loud noises will cause them to run, or fall on the ground holding their ears, as well as direct as much attention as possible from the nearby area to the car. This makes it much easier to track the thiefs even if they do nab the gear.
*Put the alarm brain somewhere where you know thiefs won't be able to find it and disable it, under the panels are a common place for alarms.
*Modify the kickpanels to hide the hood latch, preventing thiefs from getting there and disabling the battery.
*Use odd type of screws to prevent thiefs from stealing your equipment. Some screw types are star and square. Rarely would a thief carry anything other than a flathead or a phillips.
*Try and get your insurance provider to cover your equipment.
*Don't leave things interesting in your car like cd players or cell phones. Once they go in for one thing, they may move on to other things.
*Use good fuses, last thing you need is stolen material, then the bare metal lights your car on fire.
*If you list your car on a website, avoid including any information on where you live.
*As well as hiding the hood latch, don't forget to check how easy it is to get to the hood's wire, it can just as easily be opened this way.
*Disable the wire going to your trunk. Chances are, a good chunk of money is in your trunk rather than in your car. Remove the cable that opens the trunk from inside the car, not just the switch (don't just lock it). Removing the cable itself means you can only open the trunk with the key, or some very fancy lockwork, which is going to be much less likely that someone knows how to do.
*If you can open the seats from the inside of the car, try and disable this the same way you disabled the trunk.
*Having a second battery is a great help. Most thiefs won't consider the battery in the trunk being the battery attached to the alarm, nor do they have any way of getting to it. If you have two there are a number of options from there, such as attaching 1 alarm to both, 2 alarm to each, or a variety of options to make use of the battery that's much harder to reach.
*Hide as much as you can. Even if they can get access to your trunk, hiding everything behind a grill or a plexi glass wall will slow them down greatly, and if the items are screwed down with the square screws, there's probably not much they can do besides punching your speaker cone into damage, and a speaker reconing is much cheaper than replacing a speaker.
*All these things can slow the person down, but don't forget that the simplest thing to do is break the glass. If you can, replace the glass with a stronger plexi glass or something less easily breakable. If you can, attach sensors to the glass so that the alarm is off when the glass shatters.
*Blue polics beacons are also an option although somewhat overkill it's better to be safe. When the car is broken into, as well as the alarm which people don't pay attention to as much since people do make mistake with their own car, a flashing blue light will definitely draw attention.
