You will have to see what the DB rating is on each horn. The lower the DB the lower tone sound the horn will have. You can use two horns with different DB ratings for a high low sound effect. Hook the horns up to a battery in the store and blast away!:devil: How about this set up? RICK
As MBZTECH mentioned, a high/low combination gives that full rich sound. Basically, two horns are playing a chord instead of a single note. The full size cars came with two horns and the smaller cars came with just one. It is the twin horns that made them sound manly. I bought a factory reproduction hi/low combination from American Autowire but have not installed them yet. It has been a while since I messed around with music but I believe the factory used A and C notes.
