Stereo question.....
There are also HU adapters that make the job easier. But I just don't see a need to go all that crazy. Get a nice amp, nice sub...change the front speakers if you REALLY have to and buy an MP3 player that can integrate with stock HU (PHAT). That is all you need.
Honestly you've got to be a lot more specific on what it is you are trying to do and if you have to ask how complicated it is to change out the stereo and the changer, you probably should let pros handle it.
game on.
To make it all work you will need the following:
1. Metra 70-1787 harness, which can be found <a href="http://www.soundcity.com/products/31061.html">here</a>
2. Euro antenna adapter, found <a href="http://www.crutchfield.com/S-qp1DFedxYrI/cgi-bin/ProdView.asp?g=119400&I=12040EU55">here</a>
3. 2 ground loop isolators (well, i needed 2), found <a href="http://www.radioshack.com/product/index.jsp?productId=2062214&cp=&origkw=ground+loop &kw=ground+loop&parentPage=search">here</a>
4. Trim plate, which can be found <a href="http://homepage.mac.com/risowu/OSIR/TT_dtwo.html">here</a>, I have the carbon fiber trim plate, but you can also get a trim plate from crutchfield that needs a little trimming, but I can't find the link for it...
