I'm surprised no one has responded since there are 20+ kits in the field along with more than 200 individual components from the system.
I'll provide some experience since I have this in my own car recently. I hope it will help you.
Many people complain about the Bose system in the NSX. In it's design, Bose used ported enclosures for both the door speakers and "sub" unit located in the passanger's footwell. The plastic enclosures allow smaller drivers (speakers) to be used (the speaker in the "sub" unit enclosure is only 4" for example). What this did achieve for the NSX is a very lightweight component set. Many people feel that the high and low frequency response is lacking. For the small cabin space and the weight of the component set, I think Honda did a good job and satisfying most customers when the car was introduced. However, customers definitely demand higher quality stereo performance in cars today. Aside from performance, with the exception of the known Bose amplifier reliability problems, the speakers themselves have been fairly reliable in my experience.
Our intention when designing the Proformane Audiophile System was to develop a high performance, non-intrusive, and easy to install stereo package that was as "plug and play" as possible to replace the factory Bose system compatible with both factory and aftermarket head units.
We tested various sized components and ultimately decided on 6.5" door speakers mounted on custom mounting boards, a 10" sub driver mounted in a custom made sealed enclosure, and a central amplifier driving the three channels.
In the past year, we completely redesigned our package making several key improvements. To begin, we replaced our prior speaker panel kit with a lightweight HDPE plastic material:

Next, we completely redesigned the enclosure design that increased volume while decreasing intrusion into the passanger footwell by over an 1" as well as switching to an all-composite design with a flush-mounted sub driver:

Next, after a experiencing the components made by Eletromedia Italy - manufacture of Hertz speakers and Audison amplfiers, we changed out component selection. Besides the Hertz components being phenominal in sound, the Audison amplfiers are more compact and easier to install allowing installation to either the rear firewall or the rear trunk area.
Putting aftermarket stereo components into a car is not rocket science. However, taking the effort to build a cohesive system that installs into the car with custom made NSX-specific enclosures and mounting panels is what I believe sets this system apart.
Many customers will prefer to buy a complete system that they know will function and fit correctly with out problems. This is why we offer our complete system package. We understand that choosing specific components (speakers, subwoofer, amplifier, etc) is largely a personal decision and everyone has their beliefs of what's best. It's a largely opinionated desision. This is why we offer all of the Proformance system install components separately for those customers.
Along with the recently introduced Downforce center console for aftermarket stereos:

And the ScienceofSpeed bracket kit for aftermarket stereos:

We now have every custom made component that a customer will need to install aftermarket stereo components into the NSX with out the hassle of having to custom make a part.
Now for my personal decision: we recently used our 1992 Sebring Silver our complete stereo system along with the new center console, new stereo bracket kit, and new Pioneer F700 head unit. The car has:
1. ScienceofSpeed Proformance Audiophone System (stage 2) including:
- Hertz Energy 6.5" main drivers
- Hertz 10" sub driver
- ScienceofSpeed subwoofer enclosure
- ScienceofSpeed door speaker panels
2. Downforce Center Console
3. ScienceofSpeed stereo mounting bracket kit
4. Pioneer F700 head unit
In my opinion, this setup has completely changed the car's interior and the driver's experience. The interior is much more modern with the Pioneer's double-DIN touchscreen. The navigation system in the new line of Pioneers is incredible and very easy to use. Pioneer's new head units have the navigation system built into a flash card included with the stereo - so no need to be swapping navigation CDs. The sound is incredible with the high, mid, and low frequencies well balanced. The system is "exciting" to listen to! You hear so much more in songs than what was possible with the factory system.
Every component is installed in a very clean and factory manner using the custom made parts we manufacture. I was able to compare this install to another customers recently who had his stereo installed by a "professional". His installation had the door speakers screwed into the factory inner door sheetmetal, amplifier screwed into the rear firewall's trim panels, and subwoofer sitting in an enclosure that looks like it was made in shop class.
Developing this package with all the individual custom made parts along with documenting each step of the installation has been lengthy and time consuming - however, I have a great amount of satisfaction knowing the polished level of quality the components have reached in our system.
I help this hopes - let me know if you may have any questions,
