Below is the stereo system upgrade for my 2023 Badlands. I got it with the base stereo knowing I’d be replacing the whole thing since even the upgraded B+O option is pretty weak in the Broncos. This upgrade was done as part of a rear seat delete and camp platform buildout that I just posted (linked below), so the amplifier and line output converter location won’t really be applicable for anyone else. Hopefully the rest of the installation might help others looking to do the same thing.

The primary equipment list is as follows:
· JL Audio XD1000/5v2 5-Channel Amplifier
· Hertz Mille PRO 6.5” Midbass Drivers and Crossovers (MPK165.3 Pro)
· Image Dynamics IDMAX V4D4 12” Subwoofer
· JL Audio ZR650-CSi 1” Tweeters
· Hertz DCX 100.3 4” Coaxials
· AudioControl LC7i 6-Channel Active Line Output Converter w/ ACR-1 Wired Remote
I started by installing a pair of Blue Sea Systems 7720 Fuse blocks on the fuse panel cover in the engine bay. Ford did a great job providing accessory wiring studs on the battery terminal, and a spare grommet in the firewall, so this can be wired cleanly. I ran a 4awg line (w/ 100amp fuse) back to the amplifier, and a 6awg (w/ 60amp fuse) back to the rear passenger footwell to connect to my DC-DC charger as part of my camp battery setup.
Next was running a 9 conductor, 18awg speedwire for signal from the back of the factory 12” headunit, down the passenger sills and to the rear cargo area. The headunit end of that wire was soldered to a PAC LPHFD31 LocPro T-Harness to pull the factory signal from the headunit. The opposite end was ferrule crimped and connected to the AudioControl LC7i Output Converter, to convert the signal for the low voltage inputs on the amplifier.
Speaker replacement required some custom mount rings and a custom tweeter plate since the factory system uses an odd 4" dash speaker without a true tweeter. I drew up a 3/4 MDF trim ring in CAD for the 6.5s so they bolt up to the factory hole locations. I also made the tweeter mount plates out of G10 (a composite fiberglass material) to drop into the factory 4" locations in the dash using the factory bolt spacing. A quick run on the CNC and both were ready to drop in. I did also run new 12awg speaker cable for these runs since the factory wiring wasn't sufficient for the increased power draw of the new equipment. The Hertz crossovers for the midbass/tweeter were mounted in the dead pedal on the driver side, and up under the glovebox on the passenger side.
The amplifier and line output converter were mounted to a 1/2" Baltic birch rack I integrated into the rear camp platform, so the wire runs to here were fairly straightforward. I did add a new 4awg ground to the rear of the vehicle since the seat was removed, which is the only hole I drilled into the chassis for this entire build. That was tested and verified to provide identical resistance to the chassis ground at the battery, then sealed with primer and paint after being through-bolted to the chassis. You can see that next to the +/- runs just above the rack in the pic below. I also ran the remote volume knob for the subwoofer from the LC7i, back up under the driver seat where I can easily reach it to dial in the low end for different source material.
Once that was wired up, I installed the new 4" Hertz coaxials in the rear pods and reinstalled all the removed vehicle trim. These were a drop in to the factory location after you cut 2 off the 4 mounting tabs of the new speakers. These are a dramatic improvement over the terrible stock speakers out back, even though they are just for fill.
Then it was just a matter of finishing up all the wire routing and speaker wire terminations at the amplifier. All the connections were ferrule crimped and epoxy heat shrink was used where required. The LC7i RCA output and the JL Amplifier output gains were dialed in using an oscilloscope and system test tones to maximize output without signal clipping. Volume level 23 on the factory Ford head unit was verified to be clean, with slight clipping above that level, so that was my max source volume when dialing in the amplifier gains.
Then it was onto the subwoofer which was already in a 1.5 cubic foot enclosure that I built for my previous truck. It happened to be the perfect size for the Bronco platform so no changes were necessary there. It straps down to tie down points on the new platform and is quickly removable since I pull the subwoofer and replace it with a 12V fridge for camping/overlanding trips. The Image Dynamics IDMAX is my favorite subwoofer of the many I've tried over the years, so I didn't consider using anything else for this build. It is extremely accurate and plays incredibly low and loud for a single driver (assuming its adequately powered). This is a dual 4ohm version. The top cover for the amplifier rack was machined with a pattern of hexagonal air vent holes (because just drilling normal holes would be quite lame
), which completed the install.
I didn’t bother covering the removal of all the factory trim, sill, dash panels etc. since I think that has been documented to death already, but feel free to message me if you’d like photos/tips for any of that.
My system in my previous truck was built around a 3-way component setup up front with a fully active crossover network, aftermarket head unit, DSP and sound deadening lining the entire vehicle, so I had modest expectations for the sound quality I could achieve in the Bronco without going to that extreme. I have to say that I am really pleased and surprised just how good this sounds now, even using the stock head unit as a source. It is on a completely different planet compared to the weak stock system and was totally worth all the effort. It is a different vehicle now, especially with some uncompressed source files loaded on USB through the Sync system.
Let me know if you have any questions about the equipment choice or buildout.
