I was thinking about getting a police siren for my truck to hook up to my alram. Ive noticed that nobody pays any attention to a normal car alarm, but a police siren, everyone will look. Plus the thief will want to get the hell out of there fast, cause its gonna draw a lot of attention. Just wondering if anyone has done this, or has any hints, tips etc. I was also thinking about adding a Pizo siren to the interior, I heard those things hurt like hell!
