You'll probably find more info in series I. I'm quite happy with a Kenwood 6104D mono amp (200/300W). It's Class D which is very power efficient which then only requires 10 ga power wire run to the back. That makes for an easy installation along the cable tray under the door threshold trim. The rest of my Bose based system looks like this:
Image Dynamics XS-28 front mid-tweeters.
Alpine SPS-609 rear speakers (6"x9").
Alpine SPS-1005 rear tweeters (1 cm).
Boston A. S-35 center-front speaker (3.5").
Polk Audio AA3105-A MM1040 DVC Sub (10").
4080 RHS trunk-mount Subwoofer Enclosure.
Auxmod "basic" auxiliary head unit input.
Second Skin Damplifier soundproofing.
You'd have to verify fit on some of this for series II.
