It's finally here.
Audiotec Fischer Plug & Play Bundles Curated by Trail Seven.
Since 1990, Audiotec Fischer has built reference-grade car audio in Germany — every product developed in-house, from circuit design to final measurement. They're the engineers behind BRAX, HELIX and MATCH, and one of the world's leading names in DSP amplifiers.
Every bundle arrives pre-wired and pre-tuned. No fitment guesswork. No piecing components together. No generic EQ curve — the DSP is tuned to the vehicle, not to an average of every vehicle. Factory-clean install, far-from-factory performance.
Two options, both for '21–current Bronco with the B&O system:
🔊 Helix Basics — 6-channel DSP + mono
🔊 Helix i3 — 8-channel DSP + mono
Make sure to stay tuned, we have a lot more coming your way!
Turn your volume up for this one 🔊
German-engineered amps and speakers curated in plug and play bundles built for Jeeps and Broncos (and more...).
More to come. Stay tuned.
If you've held off on adding a subwoofer to your Wrangler because you didn't want to lose your cargo floor, this one's worth a look.
The Kicker L7T 12" Solo-Baric tailgate-mount enclosure sits flat inside the tailgate. No box in the back and no rearranging your gear every time you load up. Kicker's thin-mount design fits a full 12" square driver into a 9" deep housing, and the square cone gives up to 20% more radiating area than a round sub — which matters a lot when you're running without a roof.
It's roto-molded and weather-resistant, so weather isn't a reason to keep the top on. 300-600W RMS, 2 ohm, and it comes with the mounting hardware and a model-specific install guide.
Fits 07-18 JK and 18-26 JL Wranglers. Take a look and see if it fits your build 👇
