I got a set of older Cadillac Fleetwood/Buick Roadmaster horns (4 note horn system Cadillac Buick Park avenue A,C,D,F Train)

sound great on the original cars -- my Mom had them on her car back in tha day (like mid '90's)
There are four (4) horns in the set and I need some help in how to hook the up so I avoid frying the electrical system -- was thinking just wire into existing relay nut a guy at local shop that does train horns, headlights stereo's etc said I should do a totally separate circuit with a pair of relays and separate switch
I'd really like them to just replace the wimpy factory horn - suggestions?
