Review on 🚗 Upgrade Your Vehicle's Horn with the PIAA 85112 Twin Tone Sports Horn - Black by William Anacker

This was my first experience with AMAZON.COM and I am very satisfied with the whole process from purchase, delivery and final installation of the PIAA 85112 115db 500HZ + 600HZ Sport Horn. They replaced a weak factory horn on our 2008 TOYOTA Corolla CE. No holes needed to be drilled as I was able to use the existing bolts/screws that were already on and around the heatsink support structure. They are the perfect size for the limited space under the hood and they sound great! The instructions are pretty simple and easy, 1/2 hour work which also involved removing the grill to free up my workspace. I did not cut the 1/4" positive (+) jack as instructed but instead used a spade crimped with two pieces of wire with jacks on each end for both (+) sides of each horn. I used 1 of the included ground wires (-) used for the horn furthest from the (+) standard car connector and made a shorter (-) wire for the remaining horn. I initially considered the HELLA SUPER TONE HORN but after weighing the Advantages of their size versus the potential loss of my auxiliary transmission cooler I'm glad I made the right choice for PIAA!
