I've got a 2022 F150 Supercab Lariat 500A with base audio (not B&O) on order.

Can anyone tell me:
  • What's the general speaker arrangement (e.g. woofers+tweeters in front; rear door speakers)?
  • Is there a center-dashtop speaker (I hope not)?
  • Are there only 4 channels output at the Audio Module (e.g. front L&R, rear L&R; I hope that's the case)?
  • Are all of the non-music vehicle generated signals (e.g. tones, alarms, nav & phone voices, etc) broadcast through the front speakers (I hope)?
  • OR, are there non-music things like backup-obstacle alarm broadcast only through the rear speakers (I hope not)?
Hoping to confirm I can capture a 'full-spectrum' music signal and ALL vehicle-generated sounds with only a single stereo pair (e.g. audio module front channels output) to an old-school JBL MS-8 DSP.

Thanks in advance.

Check out Crutchfield.com, they should be able to tell you most all of this...

BTDT, they show pillar and front door factory locations but have no info on rear/center speakers, nor anything on HU outputs. IME lack of info on Crutchfield only means they haven't researched items for fit, it doesn't mean there aren't OE items in those locations.

Thanks for the suggestion but the questions stand, looking for answers hopefully from the person who has one ;)

Have you done a research in any F150 specialised forum?
Usually people in the car specific forums do the research first (i know for fact that this was the case for the S550 Mustang).

edit: ah, i think you did.


Hope you get some answers there.

6x9's work wonderfully in the F150 front doors. Do some basic deadening and you can have kick butt midbass.

I've made some progress since the OP
  • It's a 7-speaker system with 5 channels out of the ACM (front tweeters and woofers on one channel per side, passive XO between them)
  • The OE system does use a center top-of-dash speaker, it's still not known if any vehicle chimes / voices are broadcast only on the center speaker
  • The OE system does broadcast vehicle warning chimes on both front and rear speakers
  • The OE system does detect an 'open/ speaker-not-connected' ACM output and set a speaker-specific DTC when that happens; it is not clear if that will trigger any nuisance like a dashboard fault warning or cause the ACM to shut down or fail
So, I'll need to do some testing once the truck is in hand but there's at least reason for hope that I can make the system I would like 'play nice' with the truck. The MS-8, amps, SI TM65, BM mkV, Audiofrog GB15 and GS42 are all components I've enjoyed in a previous install and would like to use again for this 2-way active front, rear ambient fill, and subwoofer system.

My goal is SQ not SPL, great front staging optimized for driver-only occupancy, and yes I do enjoy the rear ambient fill provided by the MS-8. My music source 99% of the time is an extensive eclectic library of CDs ripped to FLAC on a Samsung T3 USB SSD.

Here's a first cut at the scheme I'd like to make work (with no center speaker); critical comments / suggestions / questions always welcome:

Your diagram looks good. The only suggestion I would make is to ditch the tr4, it's a good part that works well, but ford wakes the ACM up constantly so your equipment will power on for no reason. It's not difficult to find a true ignition power source in the f150.

The audio-enable is the best ignition source you can get in any Ford. With the TR4 it works like factory if using the Audio-Enable from the ACM together with the TR4.

I'm just not a fan of equipment powering on every time I open a door, or touch my key fob.
That I can understand, so questions when using a 'hot with ignition on' power trigger when all speaker outputs are routed through an aftermarket amp ....
  • Are there chimes or any warning tones that you don't hear between door open and ignition-on or after ignition-off?
  • Will music continue to play, or a hands-free phone call in progress continue to be heard after ignition-off as it will (for a delayed audio shut-off period) with an un-modified system?
Compromises are often made one way or another, just want to understand what those are for each approach to the power-trigger alternatives.

BTW, comments on another forum made me realize there's a flaw in the routing between the MS-8 > Amp #1 > front speakers which I've now corrected in a rev02 diagram.

I don’t want to buy the B&O system if I don’t have too to do a full Helix V12 DSP. M1 setup with Blams and a box

can you get a 20-20k signal out the normal F150 21-22’ head unit you have? with some form of a NAV TV a interface? According to NAV their module only works with B&O or Revel amp only.

If you have a base system without any outboard factory amplifier, then please do a search for "ACM reprogramming ForScan" and reprogram your ACM to variable line output.
If flat EQ you will still have a bass boost at lower volumes, but you can use this as an integrated loudness.
You just have to set up your system with a volume level (and reduced gains on the DSP) to have a flat signal for tuning.
While doing the ForScan mods you can reroute all vehicle specific sounds (backup sensors etc.) to the instrument panel cluster, because with Ford vehicles you wont have all signals on just one pair of outputs, but rear backup sensors on the rear channels, navigation on front/center (depending on your setting in the APIM), front sensors on front channels and so on. If set to all seats in the APIM the navigation will be front channels left/right.
