Cheers Glidn good post.
Yep, standard it came with 8 speakers, upgrade was 10 speakers and then you could also have the upgrade amp option and then the upgraded amp Dynaudio option.
With the 3 ways you end up with a lot more bass, especially if amplified, using the 6 1/2" woofer in the door, with still great sound coming from the mid and tweeter. This is the system I have and everyone who has heard it is blown away by the clarity and the fact that I have such good range and no sub woofers.
Ross, pm me your number please and I will call you to discuss through various options is you like. Easiest way rather than pm or email tennis. Get you the best we can within your budget. As far as amplifiers go, you only need a 4 channel amp to amp the fronts and rears, if you run a sub too, then you can either run a 5 channel amp to amp all the speakers, or run a 4 channel, running the rears off the HU and bridging the two rear channels for the sub.
