Hi, I've got a 2010 Exeo Sport 170 with the standard audio system and I've found the front speakers to be ok with decent bass response down to 30Hz (thanks to my iPhone tone generator app!).
However, the rear speakers sound quite poor in comparison, with no bass below 60Hz. I would be interested to hear what other owners think about the standard system and whether a a Bose speaker upgrade plus subwoofer could be worthwhile on the rear speakers?
I've taken the setting the fader control fully forwards, as this sounds fine on just the front speakers. I did wonder if the amp in the boot that controls the rear speakers is set to send bass to he (non-existent!) subwoofer instead of to the rear door speakers....any ideas please?
