They Bah Blow
Wolo® - Twin Power™ 2 Trumpet Red Electrical Horn Set
If your looking for big sound, look elsewhere. This horns look the part, but sound like factory horns. I took out my custom air horns for these and now have to switch back. It took a lots of modifying to get installed. They blow, not. Not recommended if you want a louder sound. The rated DB is off.

Inadequate Sound
Wolo® - Twin Power™ 2 Trumpet Red Electrical Horn Set
Advertised as comparable to Air horns. Sorry. They don't even match the stock OEM in DB level. My mistake was not first testing them prior to installation. I already had Wolo 3 airhorns installed and swap them out for these. Big disappointment. I wanted the same sound level with functional ability to hear my passive alarm system activate when using the key fob. Not recommended.

Wolo® - Twin Power™ 2 Trumpet Red Electrical Horn Set
This was an exact replacement for a 1987 Porsche 911. Fit is great, easy installation.

Not Impressed
Wolo® - Twin Power™ 2 Trumpet Red Electrical Horn Set
Bought to upgrade the tone and loudness, it did neither. Switched on to an XC90, the stock horns are a deeper note (unless I'm missing a tone adjusting screw). The stock horns are just as loud. I will be replacing these with a full air horns kit, even though I don't want to use a compressor. The one good thing is they do look good.
