ZEN A2B is the Way to Go

Zen A2B is the way to go. Installed in my 22’ Raptor. Definitely suggest buying from the Sounds Good guys because they’re good dudes with good customer service and answered a ton of questions for me no problem. They’ve installed a lot of these and know their stuff. Keep in mind why I was originally planning to use the toslink output to my helix you’re able to keep the fading front to back and left to right with the RCAs out and it’s actually better sound quality/bit rate I was told using the RCAs vs toslink. Might not be noticeable to some depending on your input source, but may be noticeable in higher end systems. Don’t be afraid to try the RCAs out and remember to update Zen. I got clean signal up to volume 28/30 on my 22 raptor and set everything up for 25/30 max volume to play it safe. Main takeaway, buy the Zen from these guys because they are going to be able to support you during install. Thanks guys.

This kit was amazing. Didn't even have to program the bell chimes, just worked!

Interface works as expected.

Installed interface last weekend in my '22 F150. Works great! I'm using the TOSlink output to a JL VX-i amp. Sounds great. I did lose the chimes through the radio for some reason. The door open/ ding behind the dash screen now. USB programming is super basic, couldnt find where to apply the factory chimes, probably a weird Ford thing. In the web interface, i was able to hear/adjust chime volumes, but those seem different than the other ones (door open, stop you're about to hit something) chimes. Those all come through the dash now.

Sounds good team is super helpful! Thank you guys.

Ford F-150 B&O Unleashed Amp. Upgrade

I was able to complete a full amplifier upgrade on my 2021 F-150 Platinum with the B&O Unleased Audio System. I used the Nav-TV A2P unit to provide the Flat Line Level outputs coming from the factory Head unit. This required the custom B&O T Harness from Sounds Good which runs from the head unit to back behind the rear seat and allows Amp. connection to the A-Pillars and Rear Door Speakers. The remainder of the 18 speakers are available for plug-in using the PAC F-150 T Harness. I used 10 channels of amplification using the AudioControl D-6.1200 and D-4.800 amplifiers which also contain internal DSP's allowing full tuning of each speaker channel. I added an external SKAR mono amp to power the factory subwoofer. I did not replace any of the factory speakers and the system sounds at least 3 times better than the OEM system. It is amazing what 3500 watts of power can do to improve the sound! The guys at Good Sound were very helpful in getting all my wiring correct and my tuning optimized. One thing to remember is the the newer version of the NAV-TV only outputs 1 pair of RCA channels for all the front speakers so you will have to use some Y-cables to feed this into the 10 speakers in the front sound stage.
I am very happy with the amp. upgrade and thanks to the Good Sound Guys!

Nothing much could happen without this critical piece of equipment. If it weren't for this company some of us might not have a very good option for the audio aftermarket. I'd say this is one of those scenerios where it's better to be heard and not seen. This unit does it well.

Product Description

By NAV-TV — the signal processor we use in every SGS Plug-and-Play package for Ford B&O, Revel, and (new) compatible 2025+ GM vehicles.

The ZEN-A2B Plus (NTV-KIT1033) replaces your factory amplifier and converts your vehicle's digital A²B (Automotive Audio Bus) signal into clean, high-resolution 6-channel analog RCA output — the connection we recommend for every build. One unit covers both 2018–2024 Ford B&O / Revel and 2025+ GM (Chevy, GMC, Cadillac, Buick) — flip a dipswitch to tell the Plus which bus it's on.

What's new versus the original ZEN-A2B:

  • Dual-manufacturer support — Ford and GM, dipswitch-selectable.
  • Burr-Brown DAC with a bit rate up to 192 kHz (audiophile-grade preamp).
  • Ford ACM control — on Ford B&O vehicles, the Plus now DSPs and controls the front headunit/ACM outputs, not just the rear amp. Ford B&O is bi-amplified, so this unlocks higher channel counts at lower cost and eliminates the need for a separate speaker-output harness — install is dramatically simpler than with the original ZEN-A2B.
  • Completely flat audio output — no factory time delay, no factory EQ. Eliminates the need for summing devices, a separate correction DSP, or removing the factory compensation microphones.

113 dB signal-to-noise ratio. 32-bit floating-point DSP. Burr-Brown DAC at up to 192 kHz. You feed a high-end Gladen, Focal, or JL Audio system the source it deserves — no PAC-style bottleneck.

Why we recommend RCA over the optical (TOSLink) output: the RCA path keeps the signal in the NAV-TV's Burr-Brown DAC all the way to your amplifier — which is the whole reason you're buying this unit. Going out optical forces your amplifier's internal DAC to do the conversion instead, and most amp DACs aren't in the same league. TOSLink is there for rare setups with a serious outboard DSP. For 99% of Ford B&O and GM builds, RCA is the right answer.

Tuning: download NAV-TV's Zen DSP application, connect via the included USB cable, and dial in crossovers, output levels, time alignment, and per-channel tuning.
