As you are all aware, the standard audio system is lacking, especially if you spend any time with the top and doors off and actually enjoy music. It is subpar for a 2021 vehicle in any price range. Here is what I did to improve. First I tried to take the inexpensive way out and installed the Infinity 4" REF-4032CFX speakers front and rear. This did yield an improvement in sound quality and a minor volume improvement. Back in the 90's I was really into car audio and did some decent installs, so I decided to go all in and give our ride the sounds it deserves for true top off enjoyment. Here is what I have now:

Infinity Reference REF-4030CFX (4 of them)
Rockford Fosgate P1675-S 6 3/4 components
Wave Tech link 4 line out converter
Rockford Fosgate T1000X5ad 5 channel amp
JL Audio CS112LG-TW3 12" Sub in sealed box
T-Spec 4 ga. wiring and RCAs

Rather than purchase adapters for the 6.75 I made my own from 1/2 thick plastic. The stock kick panel speaker is a 6.5", but there is plenty of depth and space for the 6.75 to fit. As these were the only ones my local shop had in stock, I went with them. I did trim the back of the kick panel trim grill area (see photo) to ensure that the speaker would not touch as it travels. I mounted the tweeters to the dash top grills.
The amp is running like this:
2 channels - 4" Infinitys in the dash
2 channels - 6.75 components
1 channel - JL 12" at 2 ohms

I left the rear speakers running off the stock head unit and they only provide some minor rear fill. I tapped the kick panel speaker wiring (under the head unit) to feed the Wave Tech line out converter, mounted under the steering column. From there two sets of RCAs feed the amp mounted in the rear fender area.
The link 4 has a remote level knob that controls the sub volume and it is mounted under the dash (see photo).
I mounted the fuse to the lid of the fuse box under the hood and ran the 4 ga. wire down the drivers side and then across the back behind the seat, following the factory wiring harness. The RCAs, speaker, and remote wires are routed down the passenger side.
Originally I tired using the factory ground location towards the top rear of the fender area. This provided a lot of ground loop feedback so I ended up moving it to the location shown in the photo closer to the seat belt.
I cut the carpet off the sub box and coated it with two coats of Herculiner truck bed coating. I machined two custom t-slot nuts that fit into the oval cut outs in the tailgate. I used these two t-slot nuts and three rivet nuts across the top in existing factory holes to attach the box to the tailgate using five 1/4-20 bolts. Since the tailgate is not flat I placed some 3/16 thick rubber between the box and tailgate. I ran the wires to the sub inside of the factory wire loom and then close to the box brought them out into their own loom for a factory look.
The amp is mounted to a board attached to the fender using three existing studs in the fender. Everything is in loom or protective sleeve where it could be exposed to movement or wear. I removed practically every interior panel to complete this job and only managed to break one clip, and that was on the dash speaker grill after the third time taking it out.
Thank you to all of you who have posted photos and information on here to help me educate myself before I started the project. This system is overkill and is clear and loud enough that cruising with the top off is going to be awesome!

So consensus is that the 6.5s in the kick panels are crap! I have changed my 4” out for kickers and left the 6.5s. Meh. I guess it’s ok! My question is a quality 1 way 6.5 mid driver or a 6.5 “ sub in the kicks! Cap the highs out the way to go?
Do you think this would work off the factory head?

Looks great! I have a 10tw3 in my Jeep and RX-7, that sub rocks pretty hard.

This is the first good pics of where the factory sub goes, any rough ideas of how deep that space is? I am thinking of building a custom box and putting either a 10tw3 or 8w7 in that location. 8 might be easier and could potentially use the factory b&o panel. Just curious is f the depth is more than 7.5”. Wish I had my Bronco!

I may steal your idea to mount the sub on the tailgate
But then where do you put your hibachi and your Coors Light?

With only a single side input to your converter is everything now mono?

Love the sub. Placement. Looks good on the tailgate.

Ford used sooo many zip ties to organize these wires yet couldn't muster a single one to hold my radiator hose away from the engine pulleys 😁

Nice work! I too am curious how much potential box air space you think there is behind that trim panel where you mounted the amp. I had the driver side panel off when doing my trailer wiring and (on the 2-door, at least) there is so much wasted space behind the trim. I've never done fiberglass work but this might be a good time to learn because I really don't want to use up my limited space with a box but my rig has the bass of an alarm clock.

Hey Rem234,

That is an awesome job and I am sure it sounds unbelievable. Really appreciate you posting the photos and the items that went into your audio build. When I eventually receive my bronco, I am going to completely rebuild my audio too. Insights like what you have provided will make my design so much easier to accomplish. Thank you.

Slick!

I cut the carpet off the sub box and coated it with two coats of Herculiner truck bed coating.
I presume this step was to weatherproof it. Keep an eye on it if it gets wet often. I've seen a lot of people have problems with bedliner on wood holding up when exposed to water.

How much time have you had with the system since install? Are you getting any rattle from the tailgate? That would be my main hesitation in choosing that for a location.

I get a kick out of these posts. I think these folks are doing amazing things, and I’m a tad jealous, but with four kids I can’t even imagine having the time to do this kind of stuff. The best I can hope for is no one leaving chip crumbs all over the back seat, 😂.

I had to come to the realization years ago that there are two kinds of car washing. One with the kids and one without. Don't ever confuse the two, it will make you crazy!
