Well there is RCD500, and there is RCD500 with Sound System, which means higher output speakers and an amplifier under back seat. What I've read so far in different forums is that sound system causes door cards to vibrate, and that it does not produce significantly better sound than normal RCD500. For me these two factors were enough to cancel sound system and just go with RCD500.
RCD500 includes 10 speakers.
The amp is under the front passenger seat and its about the only way, apart from listening, to tell whether you have the sound pack or not.
