Bose Concert Single Slot

[Moro Anis]

Hi, just bought a 54 Quattro roadster with the above. I don't think it's working properly. It sounds very tinny and has no bass and there doesn't appear to have any sound from the back. Could there be something unplugged. I'd rather fix it if I could rather than have the bother of taking it back to the dealer.

sounds like you need to go into the settings and increase the base and take the fade off the back speakers!!

As you have bose there is no fade to the rear.
Go into the menu and chenge the BASS and TREBLE to your liking
