The three-way front upgrade looks very good. If anyone gets a demo, please post your thoughts in this thread.

INFO:

MB Quart is shipping four new plug-n-play audio systems for the Ford Bronco 2021-2024. They include a combination of a tailgate-mounted subwoofer, rear speaker pods, OEM subwoofer and upgrade amplifier that are customizable within multiple trim options.

The packages are acoustically tuned to the Bronco’s interior with attention to factors including open-air driving conditions, said Maxxsonics, parent to the MB Quart brand. “This is not just a Plug-and-Play upgrade — we’ve spent countless hours engineering, measuring, and tuning these packages to work in perfect harmony with the Ford Bronco’s unique interior layout,” said Maxxsonics President, Brian Sherman.

MODELS include:

MBQBRO-STG6-OEM-1 Ford Bronco 2021-2024 Tuned Audio Package: a complete 800-Watt STAGE 6 Audio System for OEM base model audio systems or aftermarket source units

MBQBRO-STG6A-1 Ford Bronco 2021-2024 Tuned Audio Package: An 800-Watt STAGE 6 Audio System for OEM B&O Audio Systems. This is MB Quart’s top new Bronco package claiming premium sound, deep bass and rugged durability.

BS1-316 6.5 + 4 Inch Ford Bronco Tuned Front Dash 3-Way Component Speakers: Delivers 400 watts of total system power with 2-Ohm impedance across a 20Hz-22kHz frequency range.

BC1-116 6.5 Inch Ford Bronco Tuned Rear Coaxial Speakers Upgrade: Delivers 220 watts, 2-Ohm impedance, and a frequency response of 55Hz–22kHz.

MBQBRO-SUBR-1 Ford Bronco Tuned OEM Subwoofer Upgrade: Delivers a 400- watt, simple boost to your factory audio system with deeper bass and better quality.

MBQBRO-302 Ford Bronco Tuned Tailgate Subwoofer System: A 400-watt tailgate subwoofer adds low-end power to the Bronco’s audio system while maintaining a clean, factory-installed look.

I’m an MB Quart fan from way back so this is great to hear. I haven’t kept up with car audio for a long time but excited to see they’re still in the game (and hopefully still as good).

I wonder why they don’t include Base 2025? I’m convinced they made significant upgrades to that system as well as the newer B&O that’s been widely documented.

MB Quart used to make some very quality products. I think they are owned by the same company that owns ppi and a couple other brands now.

This looks like a very nice setup.

A little misleading when they say a "compete" system. The stage 6 packages do not include the subwoofer yet they describe deep bass. Weird.

This is what I have been looking for. Always loved MB Quart fan too. Hopefully I can do this next year. I noticed that the B&O upgrade doesn't replace the center channel speaker. Looks very clean to install.

That is one clean package. I'm in.

Very tempting. Price looks decent also ($2400).

MB Quart of today has no relation to MB Quart in the 90’s.

Rockford Fogate bought them in 2000 and struggled to mesh their American ownership with the Germany based MB Quart. Rockford basically dropped the company into bankruptcy in 2004 where Maxxsonics bought them out. They dropped any German build/design and are now 100% out of Asia. It’s basic mass market stuff living off the past history, not to say it’s particularly bad gear, but it has nothing to do with the legacy of the German made stuff.

With all that said, some of the people who made up the original German MB Quart created a new company and are still building truly German engineered and built products.

PPI, Soundstream, and Power Acoustik are owned by Epsilon.

MB Quart, Hifonics, and Crunch are owned by Maxxsonics.

I miss my early 2000’s system that had a MB Quart Q series front stage running off of a PPI Art Series A600.2. I could hear a lot better back then.

sadly none of the Made in Germany legacies are engineered or made in Germany unless spending big .....they do nothing China can't do better often with Germans in the background leadership or consulting hahah. I do have a cheap MB Quart 8" sub just because was curious and it over delivered relative to price.

The MBQBRO-SUBR-1 OEM Subwoofer Upgrade looks cool but in reviewing the install video and documentation it appears it must be paired with the MBQBRO-STG6A-1 800 Watt STAGE 6 Audio System for OEM B&O Audio Systems...

We need nakamichi to represent

Hey guys,
Does anyone know how this would work with the Sync system? I’ve heard that any installed system without ForScan or other intervention will not be worth the money. This system doesn’t seem to address that. Any thoughts from you guys?

I believe for the base system it is tuned to over come the limitations of the factory eq. For the b&o system it replaces the factory amp and works from the a2b bus, so it’s a clean signal.
