I have a 2016 Corolla LE. I want to replace the OEM horn with the Wolo Maxi Sound model 320-2T (high and low tones), each horn draws 7 amps for a total of 14 amps. Wolo’s installation instructions state it is important that there is a 15-amp fuse in the horn circuit. My corolla came with a 10-amp horn fuse and a 20-amp Denso horn relay. Question: If I install a 15-amp horn fuse, will the current fry the wire from the relay to the horn(s)? I cannot find information on the AWG size of wire. From inspection it appears very thin, 18 AWG to 20 AWG maybe, and its length from relay to horn is from three to six feet. Question: What is the size of this wire? I note that high end Toyota cars which have two horns are equipped with a 10-amp horn fuse. Question: If I install the Wolo horns and leave the 10-amp fuse in place, what is the probability of blowing the fuse? Thanks for any help.
