Adding aftermarket sub to B&O unleashed

[flynavy]

You will like that setup. In my truck I have navtv zen a2b unit toslink into an audio control DM-810 DSP. I have 3 amps in my truck. I have an audio control d6.1200 powering focal K2 power components 2 way for the first 4 channels and the other 2 channel going to some focal utopia 3.5”wm in the dash on each side. The second amp is an audio control ACM 4.300 bridged power k2 power coaxial speaker in the rear. And the final amp is audio control LC1.800 power a JL audio dual 12” stealthbox. All this with my doors and cab sound treated. Right now I am loving the clean, crisp sound.

How did you pull a signal for front speakers and tweeters? On my 18 I used the for-ck harness so it was plug and play.

Well I got the stealth box installed and although I’ll have to break them in, initial impressions are fantastic. Expensive but it’s clean and sounds incredible. Mounted the knob beside the parking brake and I think it looks pretty good and is out of the way.

Do you have the inverter under your seat? I am interested in the stealth box and have the 2kw package.

Bump for any updates in terms of where (or how) to tap rear sub/speaker channels. Do we know if there is roll off in those sub channels with volume?

Planning on installing a Kicker key 500.1 sub amp, and a JL 8" slot ported Microsub from previous vehicles.

Anyone have pics of their wiring, a schematic, etc? I haven't removed that seat yet, but hoping someone has and can share

Can we pull power from the inverter area (factory distribution block perhaps?).

24 hours into ownership and thinking upgrade already lol. While I don't mind the bass response (better than average for OEM), the mid/treble (center channel in particular) is over powering to my ears so hoping to balance it out. I prefer basic stereo sound, but it does sound better in surround, so perhaps we can attenuate the center somehow and knock it down a few db's, or I am going to keep a hat/gloves on it

I just ran the power cable directly from the battery to the rear myself so can’t speak to pulling off the inverter under the passenger side rear seat.

In terms of tapping into the sub channel I merely cut the connector off the factory sub and put the cables into a JL LOC 22 and then out to the 1000 watt amp then to the 2x12 stealth box. There is audio roll off on the bass channel still throughthe B&O processor when the volume is up so the additional gain knob helps to counteract that when necessary.
With the addition of the subs and balancing the sound settings out I’ve come to quite enjoy the system! No hat or gloves required on the Center channel and I do keep it in ‘surround’ as I agree it sounds better.

Much appreciated, do you recall which channels were pos/neg on the sub?

interesting that the tweeters and rear doors are powered by the acm, and the rest by the dsp in the 18 speaker system.

So has anyone tried pulling power off the inverter?

I walked into a local shop recently where they had a 21 Plat in the bay doing a complete audio workover on an Unleashed. I asked the price tag: $4K

From experience $4K definitely won't cover a complete Unleashed overhaul but should address amplification and a sub replacement. I've got about $4.5K (MSRP) of equipment into mine as described in this thread: (1) B&O Unleashed Upgrade DIY Thread (Sub & Amplification) | F150gen14.com -- 2021+ Ford F-150, Lightning EV, Raptor Forum (14th Gen) | Owners, News, Discussions
