I have an LTZ and was wondering about the stereo speakers.

How many way speakers are they? 2-way? 3-way? 4-way? What sizes are they?

It appears to me, that the locations of all 8 are as follows. A-posts, Front doors, C-Posts and Rear Shelf.

Anyone have anymore info?

From my own research the system consists of 2-tweeters in the A-pillar, 2 6 1/2" mid/bass drivers in the door, and 2-way 6x9's in the rear deck. The 6x9 woofer cones in the rear deck are the subwoofers.

To piggy back off of that, the 6 1/2 drivers are in every door for the upgraded system. Also, the amplifier is behind the trunk lining on the passenger side, next to the tail lamp (this is for the upgraded system). I don't know the wattage, though.

210 watts, which I thought was weird b/c the AURA's is 240 watts...

I have not looked my self but are there any factory accessory sub unit? Like one that mounts under a seat?

I recently removed my rear seat bottom and trust me, there's no room. I just added a 1200 watt mono amp and 12'' 1000 watt sub in the trunk of my 08 mali....all from walmart! Bumps pretty good too!
