Alarming Tones

Ever since I changed my car alarm in '97 (the very same week I got the car), I am very used to the tones generated by my car alarm. But after more than a decade, the speaker is, well, suffering from a permanent case of larygnitis. It was then, that I sent my car back to my friend to have another installed. Because I was tight on budget, I opted for a single tone since the original tone costs RM85 upwards and it was not in stock. From that day on, I regretted my decision. Fast forward four months later, I scouted another alarm at Pasar Road and after some tests, it was loud and almost fits my original alarm speakers. So, I decided to rewire my on my own. I mean, what can go wrong?

This is the RM25 6-tone made in China horn

And this is the single tone alarm horn. Which incidentally,
is the same as a Proton Saga car which I hated. A lot.

Swapping the two horns is quite easy. All you need to
do is to remove the nut and the stand and then bolt
it to the existing stand in the car.

There! All done! Unfortunately, the sound that came
out was muffled. The funny thing was, it was extremely
loud when we tested it in the store. Maybe, when I
have the time, I will try to switch the polarity around
or test the car's battery voltage. But if everything is
OK, then I might need to buy another horn speaker.

WTF.... I mean, its just a simple swap, right? How bloody complicated can it get?
