Hella Supertones

[rd02SiR]

Are hella loud!! Just installed a set in my car and my buddies 05 sti. Install was pretty straight forward, came with a relay, and wire it up ourselves. Much louder over oem.

[BigBurch422]

been planning on doing this for awhile now. where'd you order them from? and where'd you mount them?

[rd02SiR]

I got them from a local shop. Mounted them in the same place as oem. Put the relay in the engine bay.

hmmm may have to pull the trigger n do this soon then! post some sound clips if you can dude.

[rd02SiR]

I'll try, but videos really don't do it justice. I do kinda wish they were a lower tone, but the high tone really pierces better.

Any DIY photos?

Any DIY photos?

Unfortunately no. But it's some what easy, and this is coming from a guy who knows red is positive and black is negative. The diagrams they give you are kind of vague. I used 2b, or those who are doing it.

Pretty much get about 10ft of 12-14 gauge cable, female connectors, and a few eyelet connectors.

You will cut the plug off the existing horn wire. It's only one wire. That goes to the relay. You will only need to use one of the two, I used the drivers side just to use less wire. The passenger side is obsolete, so I tucked it in.

You will use another wire, one for each horn, that will connect with each other, and having a female connector at the joined ends, and connect to relay.

The second wire coming off the horns are the ground and can be attached to the bracket. It won't matter which is ground and which is getting power. Dunno why this is, but it works either way.

The next one is the ground conning off the relay to anything metal.

The last would be attached to the positive off your battery. Some recommend a fuse, but I didn't use one.

On the diagram, it tells you which wire connect to which prong and just connect them to the number on the relay, it's marked in the bottom, next to the prongs.

Again, on the given diagram, I used diagram 2b.

If you have any questions I'll be happy to help. I might take a pic if the relay and try to make sense of it, if this doesn't make sense.

I've been wanting to do this too.

[rd02SiR]

maybe this will help?

Blue= ground, this is also where you can use the crimpable eyelets.
Red= where is used Female Crimp style connectors.
Green= This is your OEM plug (single wire) that you're going to cut. Use another Female connector at the end of the bare wire, then attach to designated number on the relay prong (86)

So..

Relay prong number
85=ground
30= battery
87= the two horns
86= existing horn cable

I had'em on my old whip. I swear it save me from getting crashed into on a few occasions. Got any pics of them installed?

[rd02SiR]

Sorry no pics. Can't really see them, they are right behind the fog lights, oem location.

i just installed a set of Supertones today on my EP3. they are A LOT louder than stock horns. wiring is a bit of a b!tch but if you follow the drawing diagram you should have no problems.

I have these too, now when I honk my horn I don't feel like a homo
