Sub/Amp Install





Let us know if you figure this out.




I remember way back when I had an 01 E55 (god I loved that car—it was so raw), I had Clarion “Pimp My Ride” and they put a sub woofer, amp and even a purple light bar in the trunk. Replaced all the speakers in the car. Incredible sound. I could go to a stop light in LA and out boom box the lowriders!

It's nothing to be afraid of. I had a 2011 Jaguar XJL also loaded up with electronics. It's pretty straight forward, you tap into the existing sub, run power, ground, and you need a line inverter and you're good to go. It's much easier when the battery is in the trunk, otherwise you have to run power from the front battery to the rear of the car which is just a pain in the *** (removing floor trim, etc).
OKB:
Wow is that what comes with the high-end Burmester? That sounds like the right mix of speakers/sub. I wouldn't have paid extra for the upgrade considering the cost, but if you got it, rock it! The non-high end unit is garbage in my opinion.


Even the H-K in the W212 leaves SO much to be desired. My old 2001 Lexus LS blew the E-Class sound away.
I still remember when I bought my first MB, in 1988. I asked if there was an upgrade to the wimpy little Becker stereo it came with. The sales consultant told me, "Sir - customers do not purchase these automobiles to listen to the radio."




It really have a strong bass and I blew the trunk woofer. Im pretty impressed with it over all and its better than having to put a new system in. That was one of my hold outs finding the car.





AMP and sub are installed but... tapping the speaker wires in the back is causing the sub to not pump. It's moving but nowhere near the level it should be.
I need access to one of the speakers to eliminate the factory amp. But damn it if these speakers aren't hard to reach. The rear deck isn't accessible through the trunk. We think we need to take the rear seats out first but we wanted someone to chime in with experience (a MB mechanic etc.) preferably with directions or a blow out of removing a speaker that would get us access to tap the speaker thus bypassing the factory amp/system.
The good news:
Battery is in trunk (good for powering aftermarket amp) and obviously plenty of ground sources.
Factory amp is also in the trunk.
Bad news:
The factory system is turning down or doing something to my sub so that it doesn't do much pumping. Pretty much worthless.
Next steps:
We tested the sub and amp bypassing the system and it pumps!! So now we need access to a speaker. The easiest one to reach. I'm thinking rear deck.
Since I didn't do the work I failed to take pics (I know, I'm worthless).
But I can tell you to pull out all the rear trunk padding (everything in black). Left side is the factory amp behind the rear seats (now exposed) is the battery. Right side is fuse box for tapping to ensure the amp cuts on and/or off when the car is in/off.
What we got after we were done:
Powered amp, sub working albeit extremely low. It's like the car is saying no... not so much bass. So the sub is moving but very quietly. It also didn't seem to hit or be in sync with the actual bass drops with the music. It was bassing but off beat if that makes sense. Almost like it was bassing based on a sound that wasn't the bass drop.
Again I'm no audio expert so my terms are my terms and not necessarily the views of my backyard mechanic.
He stated however this is a cake job. The challenge is the need to tap an actual speaker which Mercedes did a great job of hiding behind all types of ****.
My ask:
Do we have an MB mechanic or someone that has
-Replaced a speaker in this car (doubt it)
- If so tell me how to access a speaker
-Has any idea what we are doing wrong that's causing the car to turn down the sub
In the words of my friend "can't you just buy a Nissan or something like everyone else".
By the way I trust him. I've done complicated cars before (other Mercedes, Porsche, Jaguar). Like an oil change **** is pretty standard albeit with some nuances. You never need to tap into any other electronics which made me more comfortable.
Help! I'm bass starved.

Just don't go overboard with power and size. A diecent power combined with a quality components will give you a much nicer and balanced sound compared to one you will get if going for extremes.




Definitely not looking to rattle the neighborhood. What I'm saying is, the sub isn't outputting much if anything. In other words it's as if the sub doesn't exist. Clearly something is wrong. If I can get to a speaker to tap then we'll be in business. But I don't want to rip up the car "trying" to get access to the speaker. I'd like instructions.

That sucks Lexnoir, I bet it is an easy fix just have to get to someone who has worked on these cars. Maybe try to talk to one of the mechanics at your local dealerships. This is what I mean with these cars being complicated to mod anything on. everything is wired in to work in harmony. One little disturbance can cause a domino effect of problems.Good luck with figuring it out. Keep us updated. Okbarnett do the speakers in the door look like this? this is what I have in the doors.








The Burmeister standard audio system processes audio and provided limited frequency ranges to each speaker channel. It seems you tapped into audio signal for a speaker with low frequencies reduced by Bermeister's crossover. I know you have been looking to tap into signal from a rear speaker but I'm pretty sure the lowest frequencies are sent to speakers in front, not in the rear. The Bermeister system focuses its soundstage in the front and they put their deepest bass up front, specifically to subwoofer under the dash in the fire wall.
