Which Is Louder???

[XTO]

we all know that stebel nautilus is a bad ass horn but some people say its the SNFL horns that is the loudest out there so my inquiry is this which is louder "1 SET OF SNFL HORNS OR 2 SETS OF STEBEL NAUTILUS?" just wanna make sure which is louder before purchase, and if possible which set is least to be a problem in terms of installation, space, power consumption, etc. BTW my ride is a toyota vios TIA guys

try mo muna kung kakasya sa loob ng front grill mo ang 3 trumpets

ng SNFL horn plus the compressor. baka nga 2 nautilus mahirapan

pa ng pwesto. ngayon kung parehas kakasya, SNFL ka na.
