Intro: Tutorial: Installing Hella Supertones on a 2006 Subaru WRX STi
Learn how to install Hella Supertone horns on your 2006 Subaru WRX STi. We also used a wiring kit from Lightwerkz.net. You can create your own wiring harness if you wish from store bought materials. And remember, you can be creative with where you mount the horns, we got a bit lazy and hooked them up to the easiest spot available.
