Setup, 2003 VW Jetta GLI

I am new to the12volt but i hear that you are are the best when it comes to car audio. I just bought a 2003 VW Jetta GLI. It is my baby and it took a lot of hard work to get it. It came with a decent stoock system, but it is stock and it still needs much improvement. I want to keep the install small and clean. I want to put in an Eclipse AVN5495 Navigation system. I don't think i will be upgrading the speakers right now, but i want some more bass. I am thinking one 12 running around 750 watts. I want the amp and sub to be the same company. SQ and clean looks are of high priority. price is not so much of an issue. I was told to look into maybe a W7 or eclipse titanium would be good. I have been to some local audio shops and i don't trust any of them. they are just trying to make a sale. but ya any suggestions would be nice. Thanks in advancevw gli
