Low Subwoofer sound
I have w211 2003 E320
It has Logic7
Comparing with other w211, my car's subwoofer sound is lower than them.
1.Is it possible to increase subwoofer's sound?
2.How to disable Logic7 (not from Comand Menu)?

I recently commenced a sound system upgrade other than replacing Command. You may look up a thread I started in the Audio Section. I have not got to the subwoofer yet; that will be last stage of upgrade.

Is this something you've noticed recently or has it been like this from the start? One cannot disable Logic7 using the same setup, though one can disable its affect using CleanSweep if feeding an external amplifier.

You see, the subwoofer vibrates, when I increase sound, but it doesn't give enough bass. Other w211 when increasing sound, you can feel the bass waves, standing near the car, but my is not so.
And what is CleanSweep? Is it installed in the car?

There are two defect possibilities, the amp or the subwoofer. You can check both with a single test for which you will need to get hold of large speaker, a subwoofer or a working speaker 5 1/4" or larger (its watt capacity is not very important for now). It does not matter if the speaker you use to test is not a subwoofer; we are trying to establish if the defect is with the source (amplifier) or the subwoofer. It is relatively easier to replace the subwoofer if found to be defective. You will need to remove harness connector from present subwoofer and tap the harness using Wire Tap-In Squeeze Connectors (Radio Shack $2.19) with speaker wire attached to external speaker. You don't have to blast the sound to verify if the Command amplifer or subwoofer is at fault.
If it sounds clean at a reasonable volume, then its your subwoofer at fault; if it sounds fuzzy or vibrates, then your Command amplifier is at fault.
Let me know if the above makes sense to you and if you can accomplish the above test.

Well? Any luck?
I think it's true, because when I was trying other w211 subwoofer power, they didn't have Logic7 Surround system installed.

Not certain if bass is affected but I remember for MY03 poor sound quality while in Logic7 (detected especially when the fader is applied to rear) was an issue. Depending on version, resolved by updating the audio gateway (AGW) software or component replacement.
Procedure to verify software condition:
- insert a CD
- set fader to rear
- select Logic7
- listen for any interference
- select standard mode if interference is no longer audible, AGW should be checked
