Horn Upgrade

Can we all agree that even the premium horn sounds like it belongs in the car that Urkel drove in Family Matters? I have purchased 3 different horns now and the first set didn't work, and the next two (sets of 2 horns) were not a lot better.
I have noticed that there is only a single wire going to each horn so I assume that it is grounded to the frame with the bolt that holds it on.
I would love to something just short of an actual train horn but I am not very electrical wiring savvy. I would love to just go to the junk yard and fine a horn out of any 1970's vehicle, but they all seem to have 2 wire +and - terminals.

I don't share your opinion about the premium horn, mine sounds fine.
Most two wire horns (+& -) are just that. Older models had an "accy" hot (12v) connected to the horn and used a ground through the horn button to complete the circuit. With today's electronic gismos you would need to put a multimeter on the single wire and verify it's hot when the horn button is pressed ( I'm 99% sure it is) Then add a neg pig tail from the horn to any ground point, one of the mounting bolts should work fine.
Thanks for that, and the quick response. I will look into it and see if I can find one that will work and sounds like a 72 Nova.
Welcome to the asylum Torin.
What is the ampere limit for the horn? I bought an air horn with a small compressor.
I think that with those air horns that use a compressor, you will need to hook up a relay for the higher current draw needed for the compressor.

The PIAA 85115 Superior Bass Horn set is a good option if you want something lower in tone than the Toyota premium horn. The horns are 330hz/400hz vs 400hz/500hz on the low/high horns.
+ Toyota wiring adapter:
I'm happy with mine. Didn't use an adaptor though. I reused the oem horn bracket to give it more space for install.
