SubiSpeed Hella Horn Kit
Hella horns can increase situational awareness for drivers in your vicinity. To simplify installation, we've made a vehicle specific bracket and wiring for these popular horns.
The center of the Supertone horns are black from the factory and the center of the Sharptones are blue. This will not change even if a custom grille color is chosen.
SubiSpeed Installation Video
It was important for us to make a vehicle specific bracket for the 2015 WRX / WRX STI. We wanted customers to be able to place their horns exactly where they wanted to without interfering with the front grille or radiator. The mounting bracket uses two points to secure itself firmly to the vehicle.
With the mounting location and factory plug design in mind, we made a harness to simplify the installation. It includes a 12V relay and inline fuse.
Hella Horn Plug and Play Harness V2
This newer harness is plug and play. For 2015-2017 vehicles, just connect it to the old driver's side horn plug (disconnect from original driver's side horn). Then use the heat shrink to cover this connection. Connect 1 pair of wires to each horn (1 red, 1 black wire). For 2018+ models, you must trace the passenger side horn harness up to where it connects to the main headlight harness AND choose the EXTENDED version. Use this connection for the plug and play harness.
NOTE: You MUST use the heatshrink over the V2 harness connector and the OEM connector.

Makes the car look more aggressive and a nice addition. Horn is stupid loud and will crack anyone's attention. Super easy to install and comes with a couple zipties for a nice hold back on the wiring.
The wiring harness made the install super easy and with the video it helped out a ton. Hardest part was putting the bumper on myself. I ordered the red thinking the horn part itself was black not blue. Also the connectors on the horns were facing up after they were put on the bracket making the wires very visible. I tried to flip them around but the nuts were way to tight to take off.
Great look and sound
I purchased the red superfine for my 2015 WRX. The instal was very simple bolting everything on and wiring the the battery. Subispeed's bracket lets you customize how you want it, and the harness also helps for the easy install. The sound is also very good. Highly recommend.
Love the Horns
I went with the Sharp Tone horns and the full kit with bracket and harness. Love the sound of the new horns and they look sweet behind the grille. The full kit is a must as it makes the install much easier for sure. The only extra I did for the install was to cut the eye ring connector for the ground wire ever so slightly to turn it into more of a fork connector. In the install video mounting point the washer wouldn't come off of the bolt and I wanted to get it in between the washer and bolt head for a better ground contact. I also used some heat shrink (wife works for 3M so I have a ton) to fully cover the connections into the OEM horn connector to better protect it from the elements. All in all very pleased with the upgrade! Definitely recommend!
