4) NEW KICKER DS65 6.5" 200 Watt 4-Ohm 2-Way DS Series Car Audio Speakers 11DS65
Installed these as replacements in a 2007 NBS Silverado - non Bose.  Also installed is a new BOSS Audio BV9561B (7&#34; DVD receiver), back-up cam, Kenwood KAC7005PS 5 chan amp and a BOSS Audio Phantom D10F sub.  The speakers keep up just fine. In fact I can go too loud for me without distortion.  For the price you cant go wrong..
