I have a 05 base Roadster and the original sound setup is not what I expected. I don't want major modifications in my car so I was thinking on installing the limited setup. As far as know, I can keep the same head unit, just would need the amp and the 2 shallow subs. My questions:

- What else I would need? Anybody would have a list of them?
- Who sells the OEM sound parts (besides the dealers, of course)?
- Is the installation something easy to do?

I know many people do not like the limited setup either but for me it would be a major improvement already.

Thanks
