I just joined the Xfire fraternity. I purchased a 2005 Base Roadster with only 20,000 miles and I love it.

I would like to upgrade the base stereo system a wee bit. I know many here have already been down that road and was hoping for some advice.

I want to keep the stock head unit. I like the way it looks, that's the reason. I will be watching eBay for a stock nav head unit, but that's the only change I would consider in that department.

I want to upgrade the components in the doors and add something for a bit of bass. I have owned Infinity Kappa and Perfect components and subs in the past and have always been very pleased.

So... Can anyone recommend a component set for the doors that will fit for certain and a small sub that I can put in the opening behind one of the seats? And where can I hide a small amp for the components and sub? Do I need some sort of converter for the head unit? I believe I read it only has speaker level outputs?

Has anyone else upgraded just the speakers in a base roadster and would be willing to share pictures/advice?

Thanks!!
