The M3 started with BMW’s factory Harman Kardon (688).

We tore that limitation out at the roots.

Speakers

• 3 Pairs Morel IR-BMW42 — Direct-fit 4” components 100W RMS @4Ω • 300W Peak • 50–2500Hz

• Morel IR-BMW42CTR — Direct-fit component center channel 100W RMS @4Ω • 300W Peak • 50–2500Hz

This car runs all digital. No analog degradation. No noise. No excuses.

Amplification & DSP

• Audison Forza AF M8.14Bit — 8ch amp + 14ch DSP (1120W total) 90W x8 @4Ω

• Audison Forza AF M4D — 4ch amp (1040W total) 260W x4 @2Ω → Underseat subs 520W bridged @4Ω → Trunk sub Interface

• RDVFL AR BMW-E Digital Pre-Amp Pulls pure digital audio from the OEM system → sends it via Toslink straight into the Audison DSP.

This is the ideal way to build a modern BMW

The entire vehicle is fully sound-treated with Dynamat products. Panels feel solid. The noise floor drops. The bass tightens. The mids sharpen. Everything matters — and we don’t skip steps. To finish the look, the car wears Llumar IRX 30% all around and Llumar AIR 80 on the windshield for heat rejection without killing visibility. This build simply feels right. Premium materials, OEM-level fitment, and true performance you can't get from a factory premium audio system.

You don’t have to drive a BMW to appreciate it — you just have to love great audio. Call or DM us to schedule a demo. We’ll show you the car, walk you through the process, and design a custom system that fits your car, your goals, and your budget.
