5.0 Hella Horns

love this product, it kind of sounds like a train horn. I didn't use the relay provided I just connected it to the hold horn harness. Don't forget to add 5 more amps to your horn fuse!

5.0 Good Upgrade

Complete kit included mounting hardware and ground wire. The tone and volume are what I expected
