Query: TERRIBLE Horns

I installed these on my car. They are pathetic! They may be WORSE than the anemic horns I replaced with these. I wouldn't recommend these to my worst enemy. I checked the horn relay (replaced it). I made certain I had good grounds and full 12 volts to the horns. Still the sound is a really sorry warble. Garbage!
