SickSpeed 118db Super Tone Horns

Installation instructions were easy if you sit and read them and think about the process, its pretty simple. The harness (sold separately) made the installation MUCH easier. Upon reviving the horns, and inspecting the package, there was a small piece of plastic around the positive connector on the back of the horn that was damaged. Weirdly it was damaged in the same place on both the horns? Still it was minor and once i connected the positive wires to the connectors, I used electrical tape to close them up best I could. After finishing the install I was impressed with how loud they were.

Super loud and they really look mean behind the grill. I set mine off to the passenger side instead of centering them like some others I've seen, I really like the look it adds.

Great product and support from the K5 Optima Store, as always. I strongly suggest getting the optional relay and wiring harness as the stock wiring is not enough to power these horns. If you go the stock route, the horns are extremely weak sounding and nowhere near their actual potential.
