Rear speaker volume is low compared to front speakers. Is it adjustable (separately)?

There are several issues that may be causing the volume to be very low.

SPEAKER VOLUME:
(1) When you press the Vol+ button on the speaker does it make a beep sound? (It should, even if it can not longer go up or lower).
(2) Be sure to continue pressing the Vol+ Button to ensure that the volume does increase.
(3) While this is rarely an issue, may want to check that the speaker is charged.

DEVICE VOLUME:
*Please note that some devices have a separate volume control aside from a blue tooth devices volume adjustment.
(1) Ensure that Media Volume is on.
(2) Ensure that the volume is turned up on the device by using the devices Vol+ controls

MEDIA VOLUME:
*Please also note that the media being used (Youtube, Hulu, Music Player, etc.) may ALSO have a separate volume control aside from a blue tooth devices volume adjustment.
(1) Check that the volume within the media is turned up as well.

In order to do this, your computer must be able to support 5.1 systems! Seeing as how a person wouldn't buy this particular set of speakers without knowing that information, I'm guessing you have a bit of knowledge under your belt. You need to go into your audio device settings on your computer and you should have the ability to tweak the settings of the rear speakers from your audio controller panel. I myself have the EAX which allows access to adjusting the speakers volumes based on distance from the listener!

The front speakers are the base against which you adjust everything else.

Adjust the front rear balance for 0dB.

Readjust the rest of the speakers using the test tones. Normal audio may not have a lot going on back there.

It's a setting in the radio itself. Only VW techs can adjust it with a VAG-COM

You have to enable them and turn the volume on them up separately with the speaker config, level trim, and up/down select buttons on the remote. You can also adjust the rear speaker delay time or just hit the test tone button and adjust the volume on each speaker separately as it goes through them one at a time...

Try adjusting the frequency cut off of the sub and also play with the gain control on the sub. Turn your system up to where your front speakers are sounding as you like. Then try adjusting the sub to match the fronts so you have a good balance and blend.

Factory speakers usually have low resistance ( 2 ohm) When replacing speakers with aftermarket, most aftermarket speakers will be 4 ohm. If you want the same sound you may have to buy some resistors to put on the speakers (across the + and -). By putting a 4 ohm resistor across the connectors will now make the speaker 2 ohms which in effect will raise the volume. Depending in what vehicle you replaced the speakers the resistance will vary.

Speaker test confirms whether the speakers actually work but not the sound level you have them set at. Chack volume level of each speaker. This may be a separate button all itself.

when you feel that the center channel is low compared to the other speakers, you can go to set up, speaker set up and then level calibration. here, you can actually adjust the volume output per speaker up to +12. So in your case, try to increase the db of the center speaker and see if that will help you hear it better. Hope this helps.

Channel level output can be adjusted in the menu if you have the remote. Set the rear channel level volume higher and the fronts lower if need be, and then turn up the volume. Enjoy!
