vy II ss horns

[VTPREDATOR]

ive noticed on my car that there is 2 horns beside eachother up behind the bumper. is 1 horn meant to be high frequency and 1 low? or are they separate horns, (1 for horn and other for factory alarm)? because i only have the low freq sound when i hit the horn.

they should be both the same horns connected in series. factory alarm horn is in the top corner of the engine bay, passenger side, behind the strut top.
