Hi All

Sorry if this info is already out there, but I couldnt find anything after a few searches..

I am looking to upgrade my sound system, and am looking at;

-component speakers in the front
-12" sub (powered its own amp)
-everything else stock


AMP Questions
Wanted to know what were the specs of the stock amp that comes with the CU2?
-what is the watt (RMS) output of?
-Can it power component speakers? (around 100w rms)
-can it power the sub (400-500watt RMS)
- is it recommended to just get two aftermarket amps


Subwoofer Questions
-Is it recommended to just replace the stock 10" open air sub with another (better) 10" sub (leaving it open air)?
-Or is it better to just get a box enclosure for whichever sub i end up getting?


General Audio Questions
-The front speakers - are they 6.5"?
-The speakers on the tray next to the subs - are they 6x9s?


Just bought the Euro not even 24 hours ago and loving it!!
Thank you very much for all help!
