Meet the cleanest way to run Hella horns on your Subaru—no guesswork, no piecemealing parts. This Grimmspeed bundle pairs our proven BroTie mounting bracket with a matched plug-and-play wiring harness, so placement is rock solid and wiring is straightforward. It’s the same robust hardware and thoughtful routing our community expects from Grimmspeed: laser-cut steel, durable powdercoat, tidy cable management, and adjustability that lets you center the look and the blast exactly how you want it.
We’ve built (and rebuilt) these pieces over years of Subaru development, refining materials and geometry to survive real-world use—heat cycles, vibration, winter grime, the works. The harness uses proper gauge wire, abrasion-resistant sleeving, and heat-shrink terminals for reliability and a clean engine-bay presentation. Bolt it up, plug it in, and get that unmistakable Hella tone without butchering factory wiring.
