Kind of sounds like a bad splice? These worked well for my taps: https://www.amazon.com/dp/B00H242NNY
Nice install Matt! To answer your question, the B&O amp is physically different in the '24 models but not sure if they changed anything else with it. To me it seems the system can play a bit louder than it did in my '21 but that can also be some of the DSP tweaking they did.Thanks to everyone on this forum for your help! It’s been a bit of a busy week so I had to piecemeal my audio install.
First off I ran my power wire and zip tied it all up nicely!
Then I removed the back panel via the 2 screws and 2 hook latch screws, the rubber lip and then popped the right panel.
After removing the factory 6x9 “Sub” there was a hole from where it ported to the wheel well.
I was able to put a piece of dynamat down to cover it.
I found the ground point and ran my 8ga from there. I took off the factory connection and sanded the body for better contact.
And here are some pics of my factory B&O amp where I tapped and soldered into the speaker output wires for my key 500.1 amp
@markboris, how different is the 2024 amp? I’m still on the fence about installing an alpine Class D amp I picked up inline but this is pretty good for now.
Anyway, I set my gains (which I need to tweak) and am working on tuning now. Sounds pretty darn good so far!
Think this is what I’ll do in my 24. Seems easy with the least mods. Any others that fit as nicely in the foam like that?Followed the "Super Easy" method using a Rockville RW10CA subwoofer, which almost perfectly fits the charger storage compartment. 10" woofer really hits.
I think I am going to go this route. I may need to message Mark to get this video and directions! Glad you’re enjoying it.I went with the Kicker 51HS10. Fits like a glove. I picked up an open box from Best Buy. It looked untouched (including the wires) and I saved about $100.
Installation was a breeze thanks to big help from @markboris (of course) who offered me tips and a video showing me everything I needed to do for the "easy" install method.
The bass is better than expected and it might even get better after some break-in.
I set the crossover at about 80hz. This was good without being boomy. It needed a bit more punch and although I hate to use bass boost features, I did crank it up a little bit. I was thinking about what @markboris said in an earlier post about the rolloff below 35hz and since the kicker boost is at 40hz, I figured I'd give it a try. And wow, that was the difference for sure.
As additional info, I also replaced the center speaker with the Kenwood. I find now the system sounds best in Surround.
Also planning to go the Kicker route. Please add that info to the thread for those of us looking for a simpler and cheaper sub.
I am curious which Mach-e do you have??WARNING: This is a long winded write up of my very simple, easy and fairly inexpensive upgrade for the sub bass of the Mach-E audio system. Once I started typing, I figured I would explain also why I did it not just how I did it.
A couple of days ago, I had no intentions on upgrading the lack of low end bass in the Mach-E. The sound inside this car is decent. Not great and not bad. I have upgraded many, many cars and trucks in the last 51 years I have been driving. I currently have three other vehicles that have much better sound systems that I have upgraded and I drive all of them about equally, except the GT500.
I was finishing up my sound deadening project on the Mach-E (one on of the first things I do to any vehicle besides changing wheels and tires) and in the last trim panel I removed, came across the pathetic, cheap, 6x9 paper cone subwoofer, if you can call it that. I thought to myself, this has got to go. Some cars I revamp the entire system and limit myself to between $5000-$8000 and others I just change out the sub and call it a day. The Mach-E is one of those. I’ve had all the door panels off and even the dash soundbar cover and the speakers in this car are not of the highest quality but they sound decent and get the job done especially if you don’t need to turn it up too loud. Speaking of volume, the amp in this car measures about 5”x5” and powers all the speakers. I am pretty sure it isn’t very powerful so the speakers are obviously very efficient.
My go to sub and sub amp manufacturer is JL Audio. I have been installing their equipment since the early 90’s. No, I have no affiliation with them but I’ve just been a happy customer for all these years. There are many good subs out there and JL is not the only one for sure but they have never let me down and make a quality product here in the US. I also use their subs for my home theaters. They start at $900 and go up to $16,500!!
Back to the Mach-E sub install, I could have gone all different routes. Small 8” with built in amp all the way up to dual 12” subs with a separate amp. This car does not warrant or need that much volume as it would certainly overpower the rest of the system and you are just wasting money. As it is, even the 8” lower powered sub JL makes would be 10x louder and have a lower range than the OEM sub.
While I had a lot of options, I also had a few requirements. 1. Wanted to be able to continue to use the cargo floor in both the upper and lower position in case I needed the extra space. I normally keep the cargo floor in the upper position so it is easier for me to take things in and out and it gives me the room under the floor to have quite a bit of air space for the bass sound to come out thorough the back seats. I can still store the charge cords, electrical air pump, portable battery charger/starter, rags, cleaners, polish, etc. 2. Ease of install. Really no need to install a sub and separate amp as there is more mounting and wiring to do and not really necessary for this system. 3. Cost. While I have no problem spending any amount of money on this project, again unless I were to revamp the entire system, it is not worth it.
JL makes all kinds and sizes of subs and you can usually find something that fits your application. I prefer a sub with a sealed enclosure because I like tight, accurate bass. While sealed enclosures are not as efficient, it will have more than enough volume for this system. Ported enclosures are much more efficient but at the expense of being a boomy and less accurate. This also depends on the type of music you listen to. Classical, Rock and Pop, you probably want a sealed enclosure. Rap and electronic music you might want the ported enclosure. I listen to mainly Rock, Pop and Country.
My sub of choice for the Mach-E was the JL Audio ACS110LG-TW1 Single 10” PowerWedge+ with built in 400 watt RMS amp. I chose this because of the requirements above. Height is only 5” so fits with the cargo floor to the lower position. It has a built in amp so all wiring (only four wires plus volume control cable) terminate at the sub. Cost is $520 for the sub/amp. I did buy the optional remote volume control which I always do with their subs so I can adjust the volume depending on the music I’m listening to. The RBC-1 remote volume control is $45. Total cost including wiring and power fuse was around $610.
Before I removed the OEM sub, I wanted to test the loudness and frequency that it added to the rest of the system. I was sure it was not much but it actually does add some, just not as much as I would like in the lower frequencies which is what the job of a SUBWOOFER is supposed to do. Adjusting the bass setting in the sound settings of the Mach-E actually is controlling more mid-bass and it is centered around 125 Hz. Now after the install I have two controls, the Mach-E mid bass setting and the JL sub bass setting which is centered around 50 Hz.
I set the volume at 15, all three eq settings flat and pumped some pink noise through the system via an app on my iPhone. The analyzer was set to 80db. I was surprised to see how nice and flat the midrange was and the high end looked good too (it is supposed to have a roll off like it shows). In the first two photos of the spectrum analyzer, the first one is without the OEM sub, second one with it. There is only a 2.5 db difference with and without. While it is something, that is not much. As I suspected, most of the bass in this system is coming from the four door speakers. Adding in the OEM sub, just adds a bit more volume to the bass and doesn’t add any more to the low frequencies. The third analyzer photo is after adding the JL sub. Now of course I have the remote volume control and can vary the output but what is more important is the low end frequency. 31.5 Hz is now much higher than it was before and there is also a little more at 63 Hz all with very little effect on the higher bass frequencies. The final analyzer photo is what I ended up with after setting the bass eq of the car up +2 to remove the dip at 250 Hz.
In the past I’ve taken many photos while doing mods on my cars but in the last few years have gotten lazy but mostly forget to do it. Below are a few photos I did take while working on this. Removed the panels and storage bin in the frunk to gain access to the 12V+ terminal of the battery. Ran the blue 8 gauge wire from the terminal to a fuse that I zip tied to the negative battery wire. It was a good location for the fuse and if I ever need to access it I only have to remove the one panel across the back. In one of the large rubber boots in the firewall with a large bundle of wiring going into the interior, there was an area that looked like it was intended for more wires but closed off. I made a small cut in that rubber area and again made another one on the inside of the firewall under the dash to allow the wire to come through (it is a double wall boot). Ran the 12V+ wire down behind the left side kick panel, under both front and rear kick plates and to the rear cargo area.
The audio signal needed for my JL sub amp has to come from the OEM sub. To get to that, I pulled away (did not remove completely) the right trim panel in the cargo area in front of the OEM sub and disconnected the plug going into the OEM sub. I used wire taps and 18 gauge speaker wire on the two wires that were going to the OEM sub for my audio input to the JL amp. Green/Violet + and Gray -.
While I was back behind this trim panel, I found a good point for my 12V- needed for the JL Audio sub amp. There is a grounding point used for the B&O amp which sits right above the OEM sub. I removed the bolt going into the wheel well and attached my 8ga wire with lug to that bolt and tightened it back down.
Next was mounting the remote bass volume control. There are several places in the Mach-E to do this but I generally like to mount the control where I can easily adjust it without reaching to the dash or taking my eyes off the road. I found the perfect spot at the front of the console. The console cover that has the shifter dial and parking brake switch just unsnaps and lifts up. I drilled a 3/8” hole and mounted the control. It is easily adjustable using just one finger and you cannot see the control while seated unless you move the seat all the way forward. Ran the 18' cable along under the left side of the console then under the driver’s carpet then along the underside of the kick panels to the back and popped through the hole I had made for the other wires in corner of the padded floor.
The sub box fits nicely in the area that was occupied by the styrofoam container that housed the air pump and charging cords. I did not bolt down the sub box as being 20 lbs. it is decently heavy and does not slide at all because of the carpeted box on top of the padded floor. The two materials together are like Velcro. It’s not going anywhere especially since there is a cargo floor and a very heavy Lloyds custom fitted carpet above it. I still have room for all the stuff I had below the floor and now there is a real subwoofer too. If I want to drop the cargo floor down to the lower level, I do have to remove the charge cords and roll of paper towels. On the lower level, the cargo floor actually sits on the grill of the subwoofer which sticks up about 3/4". I can remove the grill and then the floor would be flat as it was before but I'd rather keep the grill on the woofer.
How I have the levels and controls set up: The car’s EQ is set to plus 3 on the treble (I like it a bit brighter on the top end), left the midrange alone and bumped up the bass +2 to bring up the 250 Hz that was lacking a bit. On the sub amp I have the input level set half way, crossover frequency set at 50 Hz. The remote sub volume is set around ½ way which sounds about right for most tracks I listened to . That means since I have the input level on the amp 1/2 way up and the remote volume 1/2 way up, I am using about 1/4 of the volume the sub can put out to match the audio of the OEM system. Tons of volume in reserve if I wanted to produce some rap bass for everyone to hear down the block. The turn on power for the amp is set when it sees an audio signal. I may have to change this if it drains the battery. Have had that happen in the RS if the car supplies signal to the sub for various reasons even when the car isn’t on. I can pull and ignition wire from the B&O amp for the turn on if that is the case.
Ok, done boring everyone with something that could have probably been written in two paragraphs. ?
UPDATE 05/10/21: I posted if using the 12" JL Audio PowerWedge+ sub amp on this post. #14
UPDATE 05/19/22: Instructions from Ford repair manual on removing the rear load space trim panel. You don't have to remove it but do have to get behind it so the photos in this post might help. #175
UPDATE 04/07/24: Added Kicker KeyLoc DSP/LOC to restore low end bass that the B&O system's EQ rolls off from 35Hz and down. #510
When I posted this thread it was my first Mach-E I bought in February of 2021. It was a premium. October 2021 sold it and got a GTPE and November last year sold it and got a 2024 GTP. Installed the same subwoofer setup in all three.
Did you consider the Kicker 51HS8, or did you go right to the 10? Although I like a variety of of music, I'm not an audiophile and frankly I have a tin ear. Adding the Kenwood center speaker made a quite an improvement to the sound for my ears. That said, I wouldn't mind the easy approach of a powered sub with one of the Kickers but wonder if the 10 improves the sound noticeably over the 8? Open box price difference on BestBuy is only about $50, so I would not say price difference is a factor in a decision between the two.I went with the Kicker 51HS10. Fits like a glove. I picked up an open box from Best Buy. It looked untouched (including the wires) and I saved about $100.
Installation was a breeze thanks to big help from @markboris (of course) who offered me tips and a video showing me everything I needed to do for the "easy" install method.

thank you! I’ll go with the 10”. Interesting on the volume knob. If it works for you, then it’s all good. Thanks again. I have some other projects in the queue before this one, not all car related. Mind if I DM you if I need some more guidance?
