Review on FARBIN Interface Compatible Protective Waterproof by Payton Luna

I bought these to replace the typical Japanese car horns that sound like meep meep in my 2016 Prius. Open the hood, press the 5 pins holding the front black cover over the bumper and grille, pull the pins out and remove the cover. He pushed the plugs out and pulled out, unscrewed the power to the horn. Reused current horn bracket and nut for new horns. I installed the horns facing each other. Black cover put on, pins reinserted and inserted into the holes of the cover, upper pins pressed in flush and done. Now it sounds like a real horn but not as loud as I would like.
