Sound quality is relative I suppose. Some people may think this Lexus "Premium" system is good, I do not. Though better than most stock speakers... it's muddy. Anybody who has experienced a polk audio or infinity system or better would recognize this. That said... My original post was to figure out what actual speaker sizes are in the 2008 model as this info seems to be nowhere online. I found something on the 2010 - 2011 models but since I picked up the car today... I noticed that the speaker configuration is different. It seems there is an 8" sub in the back, a mid size speaker (perhaps 6.5" ?) in each door, and 2 tweeters in the dash. BUT.... that's only 7 speakers... it says this model has 8 speakers? There is a grill on the center front dash but is that really a speaker? Another sub perhaps? I don't hear any music coming from it though... I WOULD LOVE ANYBODY WHO KNOWS THE SPEAKER CONFIG FOR THIS CAR TO LET ME KNOW BEFORE I HAVE TO RIP IT APART TO FIND OUT! If I do... I will let you all know what I find. Thanks ;o)
