Review on 🚗 SYOAUTO Car Horn Kit: Universal Fit Super Loud Electric Snail Horn - Waterproof, High Low Tone, 12V Replacement Car Horns by Ron Turner

I installed horns on a 2020 Subaru Ascent & Forester. The forester needed almost the whole day. Climbing about 2 hours. The 10 minute setup they claim would be true if you had easy access to the horns. new car not. Both were accessible from above and did not require disassembly of the front bumper. The cables that came with it were useless. You are too short. I had to search for a suitable ground and the wires are much longer. There are no instructions other than those on the website. It doesn't matter which terminal is + or -. However, the mounting bolt does not serve as a ground. One terminal served + the other had to be grounded. They aren't much louder than the OEM horns. However, they sound like a real horn compared to Subaru's toy horns. You are an improvement. They fit both cars but I had to bend the brackets on 2 of them slightly to make room.
