Aftermarket Sound System?

I'm posting this for anyone with advice/experience in VW sound upgrades. My previous two cars were completely done Alpine and I couldn't have been happier with the quality. Needless to say I am not very impressed with the factory system (distorts with the littlest increase in volume); however, I can't seem to find the 2010 GTI speaker specs (depth, diameter) as well as the touch screen radio specs. Any insight would be helpful at this point. I'm currently debating between either an Eclipse or Alpine double-unit receiver/navi unit.
Thanks!

5-1/4" and 6-1/2" will fit. Check crutchfield.com there is a search you can do for your car.

adding sub works best. The speakers aren't great but lack of low end is the biggest issue.
