Hi guys, where can I find the stats on the factory system?
Like HU RMS and Speaker range and sensitivity?

Planning out a new system.

If you're planning a system the first step should be to get rid of all the stock equipment. From what I remember the factory radio has a lower cut off around 50 or 60 Hz, basically removing all the low bass information. The stock speakers are the usual cheap paper cone factory stuff, ok, but not really good. Factory head unit doesn't put out more than 15 W RMS at most and the speakers aren't designed to take much more than that. It's a stock system in an econobox, it's not really designed to be a good system, or even starting point.
