Review on 🔊 Universal 12V Motorcycle Car Horn Kit - 130DB Super Loud Metal Disc Horn Twin Horn for SUVs, Pickups, Boats - Waterproof, High and Low Tone Horns. by Andrew Mclemore

Put these horns in my Prius and at 130dB my horn is no longer "weak"! Installation was very easy. The Toyota quick release clip fits on the terminal, eliminating the need for additional wiring. You must add a ground wire for the horn to work. I found applying soil to an anchor bolt was clean and compact. The instructions leave a lot to be desired, but if you know the basic DC connections you won't need them. Great product at a great price!
