I'm getting the Beats audio system - to be honest, I'm not sure of the difference between that and the standard audio - what's the quality like?
As far as the components, it appears to be exactly the same speakers as the 9 speaker upgrade.
The dash mounted 3.5" speakers are trash. Like extremely bad and should be replaced first thing (replacing them is pretty easy). They are shrill, like an icepick to the ear when you turn them up, and replacing them is a huge bang for the buck sound wise.
The doors are reasonably constructed 6x9" speakers, although they are single driver units (no tweeter, not even a whizzer cone). They are 2ohm speakers and are heavy on the mid-bass and anemic pretty much everywhere else. You can put other speakers in, but even the aftermarket "2 ohm" offerings will be quieter because they aren't truly 2 ohms, but something between 2.5 and 3.5 ohms.
The rear tweeters are just some odd white tweeter things they dug up someplace. They reproduce a remarkably wide range for their construction.
The sub is a 6.5" dual voice coil of unknown impedance (at least I haven't run into anyone's notes on pulling one, and have yet to dig into that part of it on my own). It actually produces more than I expected into the lows, but has a lot of bass and mid-bass overlap with the 6x9s in the doors. That causes it to be directional to a greater degree than a true sub woofer limited to low frequencies.
Then you have the amp. Which isn't remotely serious in terms of car audio, but has has tank like construction. No clipping, stable to two ohms, if the wiring diagrams are correct, possibly to 1 ohm on the rear doors. It's clean, and low on distortion IMO, and gets loud enough to cause long term hearing loss, so I'll likely stick with it long term and just replace drivers.
