Hello guys,

I try to change a new speakers on my BMW F10 which have basic audio.

So I bought a STEG BM845C. There is bass speaker, mid speakers and tweetr speaker.

So I install a bass speaker, everything was fine and OK. Then jump to my left side door panel, unistall it and change original speaker for STEG one. Then I connect the wire (it is plug&play) and try it.

In this point, everything went wrong. Front speakers are dead. Bass and rear speakers works well, but front in the door panel not.

Should it be the AMP? Because, if it´s, how is possible rear and bass speakers play well?

Thanks for any help. BMW diagnostic find nothing, no problems in ECU´s.

This is what you bought?

Double check your connections.

If your connections are good, try the old speaker. IF the old speaker is working, there may be an issue with your new speaker.

Also, consider contacting the manufacturer for technical support.
