Alarm System

[NicLX470]

Now don't laugh but I was wondering if anyone has done this, or even knows if it is possible. Because the alarm system of Lexus’s is just the horn.....is it possible to get the alarm siren from a BMW installed? Like the clip below, for some reason I am fascinated with the sound.

Is it not possible? :(

Never tried it. Take it in to an aftermarket audio shop and I'm sure they can do it. Depends on how much you want to spend on it I suppose.

Yeah it can be done as long as you're willing to throw money at it because just about anything is possible with a car if you have the money.

It's simple enough to put a cheap voltage drop sensor alarm and use the BMW siren instead of the one that comes with it. Then, you gotta carry an extra remote but it might be worth it to you.
