^^ Yeah I don't either But they are LOUD and annoying which works for me. I like watching people JUMP when i hit my horn.....LOL

 

Yea, I always hated how the stock horn gets no attention... the dumb*ss slowing down to a stop in the middle of the freeway trying to switch lanes will look around wondering who the f*ck just honked without moving the f*ck out of the way. If I honk again, I'd get the same reaction, over and over again. With my Hellas, they just jump a bit and move the f*ck out of the way. I never have to honk more than twice now. But I still want louder, and a lower pitch wouldn't be bad either...

 

Oh, I thought you were talking about the ones that need an air tank. Are the ones you have red?

 

haha, OP, I know what you mean. I had to blow the horn today at someone and I doubt they heard it at all

 

Yeah I just picked them up at pep Boys $25 I think

 

Ah, aren't those high pitched? I'm looking for something that is more of a lower tone.

 

If the amperage rating of the old horns is that close to the OEM ones, the existing wiring should be able to handle the load, assuming you're doing a one-for-one swap. If you're adding horns to the system, the wiring probably isn't sufficient.

To run 5 horns, each pulling 5 amps, the circuit would need to handle at least 25 amps. I'd design it to handle at least 10% more just to be safe. Let's just say 30 amps. According to this 12 volt DC wire chart, 8 gauge is appropriate for that circuit if the one way wire length is less than 11 feet.

The relay needs to handle at least 30 amps. The fuse should be sized appropriately for the load but not exceed the capacity of the circuit. In other words, don't use a 50 amp fuse on a circuit that will burn up with 20 amps of current running through it. In this case, a 30 amp fuse should suffice.

To do this properly, you would need to run 8 gauge wire from the battery to the horn relay and from the relay to the horns. The wire between the battery and relay would need a 30 amp fuse placed near the battery end of the wire. The relay would need to be swapped out with one that can handle 30 amps.

 

Most standard 12V car relays you can purchase are 30A.

 

The relay has 3 pins. How do I find out which pin the 8 gauge wire will connect to? Also, how would I connect it to the relay? As for the ground wire, would I connect that directly to the battery? Would each horn itself need 8 gauge wire?

87 will go to the fused line off the battery.
30 wil go to the horns
86 will go to the horn trigger wire
85 will go to ground
leave 87a un-connected.


This is one way, and how I use them. There are others.

 

Oh an no, all the horns can run off one 8ga wire. You can run it to a distribution block down there.

Here's some examples

I put Fiamm dual trumpet air horns on mine. They fit in the stock location just fine. All I had to do is run a power relay from the battery to get full power to them. Sounds just like a Ferrari.

 

I originally thought about using one of these relays. The only thing I'm confused about with what you mentioned is the horn trigger wire. Where is that located?

 

Gotcha. I'll just use one of the Kicker ones I have since I don't have an audio setup....yet

 

I used the horn plug. One is hot (trigger) one is ground.
