Your post does not state a brand, so it's not clear what horn you're looking at. It's certainly cheap though.

Do a search for Hella Supertones. People here say they're the best.

they are great in a parking lot, but doing 60 on a freeway you can barely hear them your self.

Any one knows what hella supertones are rated at?

Damn, You got scammed big time. Why not just get a trusted brand like HELLA. Sorry, but who would buy from and about the unknown on ebay. You get what you pay for, and sometimes not at all.

I got hella supertones and they work great. Got 'em for like $40 from susquehannah motorsports. If you get them though make sure you wire them up the right way...don't just hook them into the stock harness....you have to wire them directly to your battery. It will cost you like an extra couple bucks for wire and connectors. They are directional horns, so in the drivers seat they sound normal, but the first time you honk at someone you will see them turn white at the wheel and then promptly faint. I love them! BTW, i mounted them behind the grill of my WRX and they look cool too...bright red.

Lightbulb Supertone ratings..

The Hella Supertones are rated at 118db's. I betcha the stock MY01 and earlier horns are like 90db!!! YUK!

I myself got a pair of MY02 horns off of a friend of mine. Hooked the pair up right behind my grill, wired it all up to the battery. It sounds pretty aweful with the tri-tone system I have - stock whimpy horn with the MY02 horns!

The MY02's are rated at 110db - not quite supertone loud, but loud enough to get the point across!

I got the horns for free off of a friend cauz I helped him change his rear sway bar. Wiring and miscelaneous stuff like fues holder, fuses, wire taps, o-ring crimps and wire - probably 'bout $10.

LaterZ!
Darren!!

Unhappy Disappointed with Supertones

Hey, for those who have the Supertones "wired to the battery," would you mind providing some step-by-step instructions detailing what you did, exactly?

I've got mine wired into the factory positions, and I've been quite disappointed with them. I was nose-to-nose with another WRX at an AutoX event recently, so we both sounded our horns off. Mine was a higher pitch, but volume was similar. (Yes, I was standing in front of the car at the time)

I just followed the instructions that came with the horns. I also used the relay that was provided. One really helpful thing i figured out was using O-ring connectors for the connections to the battery (Slide it ove the bolt used to tighten the battery terminal clamps) and the grounds. If you plan everything out and make the correct harnesses it should take maybe an hour to do. If you do a search for Hella Install and my name there should be a really long post. I don't feel like typing it all again....let me know if you can't find it and I'll repost.

test post...i haven't been able to pm or post for awhile

ok..it works now:


first thing is mounting the horns. i put them behind my wrx grill. Next to the hood latch you will see a couple of holes in the frame. I bought a couple of nuts and bolts and attatched the horns here using the brackets attatched to the horns. You will need a few extra nuts as spacers....slide the bolt thru the frame hole and then slide the bracket over the nut. You can mess around with how many nuts you want to use as spacers. I just went to Home depot and bought a bunch of them and messed around from there. Right now i think i have 2 nuts threaded on the bolt, then the bracket, then the final nut. Make sure you get a locking washer also, so the nut doesn't back off. They look like a regular washer, but bent a little. Sorry i don't have pics to show this, but it's all just trial and error to get a fit you are comfortable with. So to summarize:

Bolt through frame so threaded side is facing engine. Then thread a couple nuts as spacers, then slide the horn and bracket on so they should hang straight down. then a locking washer, then the final nut. Now the horn should be ready to wire.

Wiring...things you will need:

-Wire Crimper
-14-18 gauge wire (whatever you're comfortable with
-Male connectors, Female Connectors and O connectors to match the gauge wire that you're using
- a few double sided connectors so you can crimp two wires together
-An in line fuse and extra fuses to match the gauge wire that you're using
-lots of electrical tape.

**I got the connectors from Home depot, but had to get the in line fuse from radio shack.

To start with...the easiest thing to do is disconnect the stock horns and leave both connectors dangling. There is another 3rd horn above the turbo that i did nothing to...i just left it alone. I also left the front two horns still mounted, just unplugged.
Next, you have to figure out (roughly) the wiring. I mounted the relay on the bolt that sticks up right by the battery, side closest to the headlight. For now though...just leave it off...easier to connect everything at the end.

For all wiring i made harnesses before hand using estimated lengths of wire and the proper connectors needed. I lost my relay directions, so i'm not sure which prong of the relay goes where, but i'll tell you the rest of the info i know.

First, i made a harness that connects on one end to the 2 OEM connectors on one end and the other end goes to the proper relay prong. Ok...start with the 2 stock connectors hanging by the old horns.
Make a 3 sided harness for this...looks kind of like: >-----

The two wires go to the stock connectors, then you use a double sided connector and attach a third wire to this....wire this to to proper prong on the relay. I ran this wire under the lip of the frame where the trunk release cable runs....then ran it through the hole by the headlight up to the battery (where my relay is mounted)

Unplug battery before doing any of this!!!!

ok...now the relay is hooked to your actual horn button on the steering wheel.

Next...wire the new horns into a relay and a ground. First make two harnesses like this to be used for grounds.... 0------

The o connector goes up to a bolt (i used the ones used to mount the horns...forgot about that, so when you mount horns like i did add this step) the other end of the connector goes to the ground prong on the horn itself....i believe it's the bottom prong on my horn. Do this to both horns...then they should both be grounded. If the ground isn't done properly, the horns won't work!!!

Now you're ready for the power prong of the horns. I made another 3 sided harness for this and ran it the same way i did for the OEM wires (by the hood release, up thru the hole by the headlight) Harness again looks like: >----- 2 sided end goes to each + prong on each horn...single end goes to the relay.

that leaves two prongs on the relay (i think, lol)

One prong is the actual power from the battery. i used an o-connector, the inline fuse and a wire: o-- = = ---- An inline fuse is just a wire with a fuse in the middle (sold at radio shack) Make sure you buy fuses too! This is to prevent blowing your new horns up....i haven't blown a fuse yet though.

On the + terminal of the battery there's a bolt that holds the clamp on the terminal of the battery. Take the nut off this bolt, slide the o ring on the bolt and then tighten the nut back on. The run the other end of the wire to the power prong of the relay.

That leaves one prong of the relay free...this is the all important ground. I did the same thing i did for the power side of the battery. Make an 0 ring harness... 0----- and attach one end to the negative bolt on the battery clamp...tighten the nut back on, then put the other end into the ground prong of the relay...


That's all there is to it. I knew nothing about wiring before i did it, but it was a fun summer project. I have 1000 miles on my set up and no prob so far.

I just typed all of this from memory, so if you have any other questions let me know...i don't check PM's so post here.

After i had everything wired and secured I put electrical anti-corrosive (forgot to put this one on the list above...$1 at home depot) on all connectors and then taped all connections up with electrical tape.

Thanks for the response. Weather permitting (and assuming I can find my schematic with the relay pinouts), I'll make an attempt tomorrow to insert the relay into the works.

I did have one quick question regarding your setup, though. You took both of the front factory wires, piped them down into a single wire, and then plugged into the relay. Was this necessary? What I mean is, could this same thing be done using only one of the factory wires, leaving room for one of the factory horns?

The only reason I ask is that for a short period, I had one supertone and one factory horn installed, and I really liked the sound. So, if I take the center wire, feed that to the relay, which then powers both Hellas, that leaves me the driver's side wire for one factory horn. Total of three horns (although I guess that should be four...I didn't notice the one by the turbo....I'll have to take a closer look).

Is there a flaw in my thinking here?

I think that will work fine. My whole thinking was i didn't want to leave one stock horn working and also didn't want to leave one connector dangling. So i just spliced it into one wire to connect to the relay. I didn't notice the third horn either until i had the two horns disconnected and i had my alarm armed and accidentally opened my trunk. My guess is it's only used for the alarm.

I think the thing that made the whole install easiest for me was doing the harnesses before hand in my living room. it's a lot less confusing when you lay it all out and know what connectors goes where etc.

I found the relay dierections btw:

pin 87 is the power to the horn +
pin 86 is the horn press aka oem connector
pin 85 is ground (battery -)
pin 30 is power (battery +)

** note also you can install a switch so that you can switch between stock and hella horns if you want...i didn't do it but i may go back just because it would be cool. There's 2 nice open switch spots right above the parking brake handle!
