New here. Just got a 2018 S569 with only 16k miles and the base Burmester system. Being how I like bass I want to add a sub to the trunk. I tried searching and found nothing particular to the W222. So if I could get some help.
1. Anyone know of a plug and play t-harness to add a sub? I searched and found some for pulling all speaker outputs into a DSP. I just want to t off the outs that would provide a full range bass signal. I guess a complete harness would work if I find a good wiring diagram and I can rewire it but that’s problem 2.
2. Can someone share the wiring diagram that covers the Amp?
main goal is no sloppy splices but the ability to just undo a connector or 2 and be back to stock.
I have a JL audio fix-86 that I can use to sum, level, and create the sub output. Also have an audio control LOC.
My 2018 S560 is currently with my installer for a full system upgrade. We are using a Nav-TV Zen M preamp to interface with the Mercedes. This is the best solution, but it's only a solution for replacing the entire stereo. It wont work for just adding a subwoofer.
I will message my installer now and ask him how he would add just a sub. I know that the the factory subwoofer is located in the trunk, behind the back seat.
I think your best bet would be to splice the speaker cables at the sub and use your FiX-86 to convert the high level signal to low level. Forget the Audio Control, that's not as good as the FiX.
Installer says the Fix would be overkill. Plus, he said the Fix would add latency and the new sub wouldn't blend properly with the factory audio. That Fix86 is designed for using factory signal to upgrade the whole system. It's overkill for just a subwoofer.
Exactly. With the sub being in the back, what we actually want to do is delay the main speakers.... but with the Fix86 only hooked up to the sub signal, then we would actually end up delaying the sub more due to processing latency. So it's going to throw the timing off worse than it would be without the Fix86. The Audio Control device should not have any latency added, it's just an analog converter.
I wonder if there is a benefit to grabbing the signal for bass off of the front left and right channels. The factory sub signal is probably processed/tuned for the small factory ported sub. I plan to go with a sealed 12w7.
Also I am curious how your setup will sound. Are you replacing all the speakers? Which ones are you going with?
I own a car audio speaker company, so I'm using my own speakers. This will be a sound quality competition/demo vehicle for my business, and my daily driver. Will post a full build log when it's complete, but that won't be for a few more weeks at least.
We are using a 1" tweeter and 3" midrange in the front dash corners / A pillars. And a 6x9" midbass will go in the factory midbass locations in the front firewall. A pair of ScanSpeak Revelator 13" subs are going in a sealed box in the tire well.
So that's 6 speakers up front, and 2 subs. 8 drivers total.
For source, we're putting in an RME ADI-2 Pro Fs-R home audio DAC into the ashtray location. That will be the main source for competition since it's cleaner than using the car's source. The NAV-TV will be there in case I want to use the CarPlay or any of the car sources.
A Brax DSP and a pair of Brax MX4 Pro amplifiers are going in. 300W x 4 from each amp, so that's 2400 watts in total.
Wow. That sounds like it’s going to be sweet. It would be cool for a plug and play package option for mixing or matching from all out like you are doing to just a sub or just front speakers, etc.
I thought we had subs in the bottom of our dash too? I also have a sub system I'd like to install. Too big to fit in my Z06.
8" Midbass speakers in the firewall under the dash. Not subwoofers. I am replacing them with my 6x9" speakers currently. Passenger side picture attached, showing the custom trim ring we 3D printed for mounting the 6x9".

Wow. Beautiful work! Is that behind the glove box?
More like under the glove box. It's probably the best speaker location for midbass speakers in any car built today. Loads bass well, and it's solid surface with little tactile vibration. Most car companies put them in the doors (bad) or BMW puts them under the seats (worse).
