2012 Impreza 2.0i Hella Supertones Install
Here's how I installed Hella Supertones on my 2012 Impreza 2.0i.
I started with these instructions: http://forums.nasioc.com/forums/show...38&postcount=1 and I DID use the relay. I made my own harness using AWG 14 wire, and soldered all the connections, and wrapped them with heat-shrink tubing. The battery ring terminal is stud size 3/8", and the relay ground ring terminal is 1/4". The OEM horn connector isn't anything that I could identify --it isn't a standard 0.250" disconnect like on previous models. I wanted to avoid cutting the OEM wiring so I improvized by using a two-prong spade connector. It fit perfectly into the conducting socket of the OEM connector, and I then taped it all up and zip tied the wires together on either side of the connection to absorb any stress. There's a threaded screw hole (M6-1.00) in the frame right next to the wiper fluid reservoir, which is where I mounted and grounded the relay: I grounded the horns to the point where I mounted them to the frame, using 1/4" stud ring terminals (I used M6-1.00x12 hex cap screws & nuts with lock washers to mount the horns). Final product: With grille: I did have to angle the horns further down when installing the grille to get the top part to fit (the part that blocks rain from entering directly into the air intake). The horn bracket is touching the rubber anti-vibration mounts that are below the holes where I mounted them, which is probably fine, though it would have been nice to mount them so that they hung straight down.

I'm not familiar with the subaru scene - why do you care to upgrade your horn?

That's why I got them too. Look on YouTube if you want to hear what they sound like.

The OEM horn is so gutless and it makes me embarrassed to use it. I will definitely do this when I have the time to order the horns and go pick them up.

There are four screws, on at each "corner" basically. Easy to see with a flashlight. You'll need a stubby screwdriver, or a flexible screwdriver attachment (what I use since I don't have a suitable stubby). It's got an led light on the end which makes it easy to see what you're doing.

Btw, I'm thinking of grounding the horns straight back to the battery instead of what I described above. I didn't bother removing paint from the frame to make sure the connection is good, and while the resistance wasn't too high (~ 0.8 ohm), I'm concerned about it being unreliable. Less resistance should mean louder horns too. Going to wait until my new soldering station arrives though.
