I have Pioneer 2950MP and 'm facing the same situation now. I installed it in one of the shops in GP road, Chennai, and I was quite impressed by its performance. After about 2 months, the left front speaker stopped working, and complained abt the same during the regular service. The service guy removed the head unit, checked the system wiring and found that some wires have been disconnected (may be due to vibrations!?!?). He said that to prevent this thing from happening, they need to be soldered, and the same was done. Now all speakers are working, but I could clearly realize that the BASS is missing. Would this be a wiring (polarity) problem as Sam has already mentioned?? Just wondering as to how the technician could make an obvious error as the wires are bright red skinned for the positive.
Please let me know if this is a HU problem or polarity problem. I don't want to meddle with my car wiring very often :-(
Thanks in advance!
