Review on Hella Stark Sound - Red Set 12V H/L Frequency Hella Super Tone Horn Set B 133, 12 volt by Robert Buenconsejo

Used these to replace the original horn in the '07 MX-5. The factory horn is essentially a single motorcycle horn. Installation issues were mainly due to the car: changing from a single small to a double large horn and access. To get to the location of the horn you need to remove the front bumper. To install them I scrapped the original bracket and made a new one from a 1" sheet of aluminum flat stock, bent it into an L shape and allowed myself to screw both horns to the L tip. The end result is a stacked horn. on top of each other far enough away from the body and the AC capacitor occupying the same space. Whether it was worth the effort was debatable after listening to before and after comparisons, but I can now say that these comparisons don't do them justice Horns. It transforms a car from less than 50W horn to almost 120W, drawing attention that the original horn could not perform.
