2023 Z performance
My 2023 Rosewood Performance Z is now in the shop for the ultimate audio system upgrade. Installation activity is expected to last for two weeks. Soundworks in Millersville, Md is the installer.

Background information:
I been an audiophile since high school and Music and Audio Equipment is a huge part of my life. What funny is High School feels like just like a few days ago (ha-ha). I really enjoy all types of music except rap and todays Pop stars. I wanted to update the Z sound system with a richer sound experience. I find the Bose system to by gray sounding when compared to my home audio system.

Back to the Z: my Z was purchased in 05/23. I been inching to update the stereo since I purchased the car and but wanted to update my home audio system first which is why this took so long to finalize for Car audio project. As Mr. Mac accurately said in his thread: ā€œAfter learning just how horrific Bose's so-called "premium" audio system is in the new Z and being beyond disappointed with its laughable performance I got to work on ripping it all out and designing and building a proper setupā€

Back in the Summer of 2023, I started my research on equipment options and costs. Early quotes ranged from 4K to north of 10K. With the better systems requiring a larger investment, I knew I had a lot of learning to do. Car audio is very different than home audio and more complex. The first realization, the CD player option was not available with current car audio products and I would need a phone or a Digital Audio Player (DAP). I hate cell phones so I picked up a DAP A&K SP3000 from a gentleman who works at the UN in NYC. I have been using that with the Bose Bluetooth module. In the grand scheme of things and on all of the unknowns I put this project on the shelf until Mr. Mac posted his project in early 2024.

With Mr. Mac posting his ā€œBOSE BE GONEā€ thread as a resource. It’s been an invaluable reference point and since he did the work himself it even more informative.

My main requirements for this new system were the following:

  • Very musical like my conrad-johnson system (vacuum tubes) at home.
  • Utilize my old sub from my 350Z audio system (JL 10w3w3)
  • Not tear up the car with a lot of customizations.
  • Not cost a billion dollars!

The system has two modes of operation,

  • the Bose HD unit, AM/FM and the XM radio
  • the High resolution Bluetooth Mode wireless connection to the DAP A & K 3100.
System is controlled by a dedicated rotary digital switch (Helix Controller) which toggles between the Bose HD unit and the DAP A & K 3100. The mounting for the switch is to be determined during installation. It may end up being in the on center console or cup holder or on the roof near the interior light switches. Volume control will be adjusted thru the rotary digital switch (Helix Controller) for the A&K 3100 unit and the Bose HD unit will use the steering wheel and front panel controls. The custom DSP presets are for the AMPs are also accessible using the rotary digital switch.

The Mosconi High resolution Bluetooth Module will be connected to the Helix Digital Signal Processor with a digital cable that will reject a very large portion of EMI energy within and outside of the car. This will maintain a higher degree of signal integrity then running a ā€œanalog cableā€.

The Helix Pro Digital Signal Processor will connect to these three amps.

  • Mosconi 4/30 (door and dash speakers)
  • Mosconi 4/10 (rear panel mount)
  • JL Audio VX600/1i
Power and Ground filers:

Harmonic Harmony EHD Filters:

  • EHD Filters Source for Power input to Helix DSP
  • EHD Filters EHD Master Ground for amp chassis.
The Speakers are:

  • Door Speakers: Audison Thesis 6.5ā€ (mid bass/midrange)
  • Dash Speakers: Blam MS 2ā€ Signature MULTIX (mid tweeter)
  • Rear Panel Speakers: Brax Graphic GL2 50mm (mid tweeter)
  • Rear Tweeter Speakers: AMTU60W1.1-C Air Motion Tweeter
  • Custom Mounting enclosure
  • Subwoofer: JL Audio JL10w3 4 ohm – Zenclosures Z sub-box


Speaker cables: Mundorf Copper Angelique Copper Silver/Gold conductors 13awg

Interconnects: TBD

I thought it was you who wrote this post since I read "rosewood Z" project. I guess you two share the same taste in colors. As I probably share the same taste in music with him 😁
