Thanks Otep. D naman problema yung additional install and wire charges. Actually, what i wanted to clarify was if that the Stebel Nautilus was like a regular horn (2 pcs - hi lo), or more like the air horns, tho smaller, with separate compressors, etc.

Sheep -> la pa ako naririnig na Nautilus (either that or nakarinig na ako pero d ko alam na Nautilus). M considering it for a big SUV, depending on its tone, its volume at kung tinopak ako, hehehe. baka kasi mahiya na akong bumusina...
