Review on Hella 002768821: Powerful Black Disc Horn Kit (24V), Universal Fit by Junior Samson

These horns are a huge improvement over the one tiny horn on my Civic '09. I just installed both horns on the same bolt as the original horn. I used about 3 washers to offset the second horn and let the horns sit closer together. Wire in parallel with two horn connections to ground and two connections per wire. It doesn't sound like a train horn, but other cars will hear you loud and clear with this update. Willie H
