Hi, I am just new at this forum and I hope somebody can help me.I am owning an 2003 X5 equipped with dsp. However the rear woofers (in the back doors) don't play anymore. The tweeters are working fine and so do also all other woofers in the front doors and also the sub woofers. Does somebody know if the DSP is broken. I have been to several BMW dealers but they don't understand anything and have no expertise as far as my experience is. Thanks in advance. Is it maybe possible that there is somewhere a hidden fuse or so....
