Installing a Sub and Amp into the B6

[NewB6]

Hi Folks, some q's that I hope you can help me out with.

Firstly, does the standard head unit in the 07 Passat have a pre out for an onward amp? I guess it dont but am hoping you guys can tell me different.

Is there a 12 volt battery feed to be found anywhere in the boot that will power my amplifier? I know that there is a cigarette 12 volt adaptor in the boot but I guess this is not suitable to hang an amplifier off. I could use this feed as the AC power to switch the amp on however I do think I need a clean feed to the battery for the amps main power in feed.

Finally, any links to a B6 audio installation appreciated, even better if there is some pics to view.

Thanks in advance
