My factory horn no longer works and is totally corroded. I bought a PIAA dual horn (500 and 600hz, 115 decibel) as a replacement for about the same price that a Toyota dealership wanted for an OEM horn. Since there is only one factory mount for a single horn, does anyone know of a good place to mount the second horn? Also, am I at risk of blowing the 15 amp fuse that was set up for only one factory horn? I am worried that the new horns will draw too much power, thus blowing the fuse, but I heard that it can be dangerous to upgrade to a 20 amp fuse. Thanks for your consideration!
