Adding Another Pair of Horns: Would It Make It Louder?

[suysuy]

I currently have a pair of mitsuba alpha in my civic, im planning to add another pair. so bale apat na sila (2 horns = 1 pair)

actually, its very loud, but i want to make it louder hehe. so kung dagdagan ko ng isang pair, lalakas ba talaga?

haven't tried mitsuba alpha. but i have tried 2 stebel nautilus, lumakas naman... though parang duet sound... 2 persons singing at the same time.

lalakas pa rin ang tunog ng busina. kung same type/model ang ginamit, do not expect na dahil sa dinoble ang dami ng busina ay doble na rin ang lakas.
