hey everyone. i've decided to get new horns on my p5, and i pretty much have three options locally- 2-tone WOLO horns, 2-tone WOLO truck horns, and FIAMM freeaway blaster horns. I'm leaning towards the truck horns, but i was wondering if i would need anything special to install them. Also, should i just put the trumpets behind the front grille? Ir is there a better place? thanks a lot.
