PURE Digital Factory Infotainment Integration for ELS Studio

[Ash @ S2i Audio]

The mono thing was just because of the number of amplifier channels I had available at the time. I've since upgraded to a 12 channel amp and running rear fill in stereo.

That said, the device is set up to preferentially direct rear fill to the door speakers instead of the rear c pillar speakers due to their tiny size and inability to be replaced by anything aftermarket due to space constraints.

If you do end up buying and want to direct rear fill to the C pillars let me know and I'll make a modification to your unit so that it can do that. Not a problem.

Sorry for the slow response - I've been manufacturing harnesses for a large distributor order all weekend. Regrettably, I no longer have analog T-harnesses on my pipeline as I need to focus all my R&D energy into next-gen digital integration (which includes your 2026 Si).

Sorry for the bad news - the upside is that by September I will be fully focused on the A2B integration R&D once I get these orders processed. I have purchased some of the proprietary technology needed to reverse-engineer Honda's protocol and hope to be doing prototype testing by mid-Fall.

Hey at least A2B allows for daisy chaining and nodes... I wonder if that would allow cleaner subwoofer add-ons or not, or if whole system DSP would still be needed.

 

[Ash @ S2i Audio]

That would be very hard to do because the master A2B node has burnt-in registers of what nodes it expects to see when it wakes up. I think you'd have to reflash the master first before you can add anything that doesn't belong.

In the case of an integrator replacing a node (ie a factory amplifier) you are just fooling the system by replicating the address of the former OEM node.

Man they really can't just make this simple to do, can they? We'd stop having to modify these cars if they would just give us good components and amplification to begin with, but no of course they would spend even MORE money complicating the process ...

 

[Ash @ S2i Audio]

I mean, it's on purpose. Automakers want to lock down more and more of their systems so that they can ensure any paywall they put up can't be hacked.

It's poop.

Mega-Announcement! We are now an authorized Arc Audio dealer!

I'm super excited to release our first PURE Digital Integrator + pre-configured DSP Amplifier kit! We will be selling these kits paired up with an Arc X2 800.8, Blackbird, or Falcon - you choose how many channels and how much power your planned system needs.

We will then reach out to you and discuss your planned system configuration and custom-configure the DSP Amplifier I/O for this setup, and manufacture a customized wiring harness for you based on the length needed and which speaker locations you plan on using. You just supply the speakers and installation accessories (like power wire, fuse blocks, etc.)

We can also sell Arc Audio speakers if you want to go that route, so contact us first if that is your plan so that we can build a custom order for you!

Looking forward to setting up your next factory-integrated high-end sound system in your Integra with ELS!

For the Type S w/ELS, the PURE's routing feeds amplified/DSP'd signal back into the factory harness, and the midranges and the tweeters share channels (i.e., wired in parallel) on the factory harness, correct?

So, to run an active 3-way front stage on the Type S w/ELS, it looks like I'd need to run a separate set of wires from the amp/DSP to the pillars/tweeters, correct?

 

[Ash @ S2i Audio]

That's exactly right, and it's the approach I would recommend (and what I am doing on mine as well).

Easier to add wiring to the pillars than to the doors....

yup, that’s how my focals are wired

Thank you both! Happy tuning!

Expanding our partnership with Arc Audio, we are now also offering pre-configured turnkey sound systems. We pair high-end Arc Audio equipment with our PURE digital integrator, extracting the most out of the incredible Arc hardware.


We will build you a custom-configured full system with signal harnesses customized for your vehicle's layout. An optical cable is included, as well as all necessary speaker mounting brackets for a direct OEM-like installation, without modifying the car permanently.


Power wiring and amplifier installation accessories (fuse blocks, etc.) are not included and must be supplied by you/your installer.





You have three choices of system, set up as performance tiers:

1. "Enthusiast" - this may be the entry point, but it's still better than most high-end factory sound systems! We set up the front stage with Arc X2 components, X2 coaxials for the rears, and a small-footprint 8" X2 subwoofer. All of this is driven by the single-chassis X2 800.8 DSP amplifier - a small powerhouse!
2. "Audiophile" - this is where you really start to pull away from the aftermarket pack, with genuinely high-end "AS" series speakers for the front stage and fill, which are components this time in the rear. While the system is still based on the X2 800.8 DSP amplifier, a second non-DSP X2 amplifier is added for the subwoofer, allowing more power to the front stage and the larger sub. This system gets LOUD and CLEAN at the same time.
3. "Competition" - this is for the person who doesn't want to make any compromises. The absolute best speakers are used in the front and rear, and the subwoofer is upgraded to a 12" SQ beast. The front midbasses get a whopping 250 watts each and the sub gets 800 watts. Why so much power? Dynamic range. If you want a sound system to be able to transport you to a concert environment, you need dynamic range for those moments that cannot be reproduced by lesser systems.

	Enthusiast Balanced SQ	Audiophile SQ & SPL	Competitor A Live Concert
Front Tweeter	X2 1.0 (50W x 2)	AS 100 (50W x 2)	RS 1.0 (75W x 2)
Front Midbass	X2 6.0 (50W x 2)	AS 600 (170W x 2)	RS 6.0 (250W x 2)
Rear Fill	X2 602 6.5" coax (50W x 2)	X2 6.2 6.5" comp set (50W x 2)	RS 3.0 3" wideband (75W x 2)
Subwoofer	ARC 8D2 8" SQ sub (170W x 1)	ARC 10D4 10" SQ sub (600W x 1)	ARC 12D2 12" SQ sub (800W x 1)
DSP Amp	X2 800.8 8ch w/ DSP	X2 800.8 8ch w/ DSP	Blackbird 8ch w/ DSP
Dedicated Sub Amp	-	X2 1100.1 monoblock	Nighthawk 2ch bridged
Optional Sub Enclosure	Sealed Box 0.45 ft3	Sealed Box 0.65 ft3	Sealed Box 1.0 ft3

The ordering process is simple:

1. Place an order indicating which Tier you want, and whether you want us to supply you with a non-custom subwoofer box, or if you plan to make your own you can exclude it.
2. We get in touch with you within 24 business hours and confirm your vehicle and discuss any unique configuration needs.
3. We build the kit and pre-program the custom I/O configuration to your DSP before shipping the bundle

If you aren't sure what you need, feel free to get in touch with us prior to ordering and we will gladly advise you!


Also, we can customize! If you want something a little different than the above standard configurations, or if you want to utilize different/additional speaker locations, send us a note before ordering. We can custom-configure a system for you.





IMPORTANT NOTES:


Your DSP will still need to be tuned by your installer / yourself if you are experienced, but the heavy lifting of setting up the right I/O and analog/digital signal mixing for the car's infotainment sounds will be pre-configured, and the harnesses will arrive terminated, labeled and pre-connected for a convenient installation.


This is a custom build-to-order package so there is effort and cost involved to build harnesses, order the speakers and DSP, build speaker adapters, and create/load the I/O file for the DSP. All sales are final once orders have been placed. We appreciate your understanding.



The Acura Integra with ELS Studio also has a 3" midrange in the doors, from the factory. In order to maximize the performance of these systems, we include a 2.5" AS250 midrange for the "Audiophile" Tier and an RS 3.0 for the "Competition" Tier, only. The "Enthusiast" Tier remains a two-way front stage to keep in line with that Tier's low-cost/high-performance design goal.
