Electrical question about multiple horns
I'm thinking maybe I'm best off wiring my own whole new circuit with heavier wire and run three horns in parallel all to a new button installed in my interior? I'm no EE, any advice for me?
Hmm, maybe I'll hook each up separately with it's own button and then I can push them all at once or musically to my content.
Maybe there is a better category for this question...

I ever junked. Full size used to have decent horns.
And you can tweak the freq some with the screw.
Get a pair of same-tone ones and tune them to a
nice epilepsy-inducing 8Hz beat note.
you need to connect them in parallel so they all see 12 volts, because they require 12 volts to operate.
simplest thing to do is remove the + wire that goes into your current horn and put it into the control side of a 20A relay. The other side of the control goes to ground. Then use 14ga or 12ga wire from fuse box bus bar or battery + to one side of the switching side of relay, other side branches out (in parallel) and goes to each + terminal for each horn.
You can pick up a 20A automotive relay from radioshack for $6.
And you should put a 20a fuse inline between battery + or fuse box and the relay.
